Unmanned aerial vehicles (UAVs), otherwise known as drones, are remotely-controlled aircraft which may be armed with missiles and bombs for attack missions. Since the World Trade Center attacks of Sep. 11, 2001 and the subsequent "War on Terror", the United States has used drones to kill suspected terrorists in Pakistan, Afghanistan, Yemen, Somalia, and other countries.
Proponents say that drones have decimated terrorist networks abroad via precise strikes with minimal civilian casualties. They contend that drones are relatively inexpensive weapons, are used under proper government oversight, and that their use helps prevent "boots on the ground" combat and makes America safer.
Opponents say that drone strikes create more terrorists than they kill. They contend that drone strikes kill large numbers of civilians, violate international law, lack sufficient congressional oversight, violate the sovereignty of other nations, and make the horrors of war appear as innocuous as a video game.
The first recorded use of attack drones occurred on July 15, 1849 when the Habsburg Austrian Empire launched 200 pilotless balloons armed with bombs against the revolution-minded citizens of Venice. Reconnaissance balloons were flown in the US Civil War by Union and Confederate forces in order to provide intelligence information ahead of a battle and to direct ground artillery fire during battle. In 1944 Japan released 9000 bomb-laden balloons across the Pacific, intending to cause forest fires and panic in the western United States.
The modern electronically-controlled military drone traces its origins to the 1930s when the British Royal Navy developed the Queen Bee, a radio-controlled drone used for aerial target practice by British pilots. Technology developed by the US Navy during World War I was used to propel and stabilize drones on intelligence-gathering missions in Europe during World War II and over Vietnam, China, and North Korea during the Vietnam War.
What Is a Drone ?
Today, companies have developed dozens of drone models ranging in size from large, solar-powered, fixed-wing aircraft to small helicopter-like devices designed to mimic hummingbirds, all with a wide range of prices and capabilities. The two most widely-used attack drones are the MQ-1 Predator (which the US military ceased purchasing in Feb. 2011) and the upgraded MQ-9 Reaper, both developed by military contractor General Atomics Aeronautical Systems. The Predator and Reaper are prized for their ability to hover thousands of feet above a target for hours and relay high-resolution live surveillance. The Predator was first deployed by NATO convoys as a surveillance and intelligence gathering tool for spotting Serbian artillery during the Bosnian war in 1995, while the Reaper was first deployed in 2007 during the Iraq and Afghanistan wars.
The Reaper is powered by a 900 horsepower turboprop engine with a maximum speed of about 276 miles per hour. It has a wingspan of 66 feet, is 36 feet long, 12.5 feet high, carries a maximum payload of 3850 pounds, and can be armed with a variety of weaponry, including up to 14 missiles or a combination of four missiles and two laser-guided bombs. This drone has a range of 3682 miles, an operational altitude of 50000 ft, and a maximum flight time of 27 hours, making it especially useful for long-term operations. The Reaper carries approximately 15 times the amount of ordnance payload of the Predator, and cruises at nearly three times the speed.
CIA and JSOC Drone Operation
Drones used for strike operations abroad are flown by both civilians –intelligence officers and private contractors– in the Central Intelligence Agency (CIA) and experienced Air Force pilots under the military’s Joint Special Operations Command (JSOC). The CIA operates on its own in Pakistan, where approximately 80 % of US drone strikes have been carried out. JSOC currently has responsibility for drones in Afghanistan and Somalia, and co-responsibility with the CIA for drones in Yemen.
One set of operators works abroad handling takeoffs and landings near hidden airfields in countries such as Afghanistan, Pakistan, Niger, Ethiopia, Qatar, Saudi Arabia, United Arab Emirates, and Djibouti. Once the drones are aloft, controls are electronically "slewed over" to a set of "reachback operators" in the United States. Using joysticks that resemble video-game controls, the reachback operators sit next to intelligence officers and watch a live video feed from the drone’s camera on large flat-screen monitors. They can turn the drone, zoom in on the landscape below, and decide whether to lock onto a target.
A stream of additional "signal intelligence", sent by the National Security Agency, provides electronic means of corroborating that a target has been correctly identified. Final approval for strikes with missiles or laser-guided bombs is delegated to CIA and JSOC officials. Drone pilots are eligible for the same combat-related medals from the Department of Defense as manned aircraft pilots.
By 2015, the Pentagon projects that JSOC will need more than 2000 drone pilots for combat air patrols operating 24 hours a day worldwide. The Air Force is already training more drone pilots –350 in 2012– than fighter and bomber pilots combined.
Cost of Drones
The Pentagon operates some 7000 drones while the CIA operates around 30, and each drone costs anywhere from $5 million for a Predator to $14.4 million for a Reaper. The Department of Defense’s fiscal year 2012 budget estimates included nearly $5 billion for drone research, development, and procurement (around 1 % of the overall DoD budget), with additional funding that is classified.
The cost per flight hour varies by type of drone, but Predator and Reaper drones cost approximately $3700 to $4800 per flight hour. The entire US drone program took 14 years to reach one million flight hours on June 22, 2011, and on Oct. 22, 2013, less than two and a half years later, the Air Force’s fleets of Predators and Reapers reached two million flight hours.
The Unmanned Systems Caucus, co-chaired by Congressman Howard P. "Buck" McKeon (R-CA) and Henry Cuellar (D-TX), promotes the use of drone technologies in the US House of Representatives. The 58-member caucus includes eight Congressmen who also sit on the House Committee on Appropriations, and from 2011 to 2012 members received a total of $2.3 million in contributions from political action committees affiliated with drone manufacturers.
The War on Terror, High Value Targets, and Signature Strikes
On Sep. 7, 2000, the CIA lobbied for Predator drones to be weaponized with air-to-ground missiles for future use as a battlefield weapon after spotting Osama bin Laden in Afghanistan, who was then wanted for his role in financing and organizing terrorist attacks against American embassies in Tanzania and Kenya in 1998.
After the World Trade Center was attacked on Sep. 11, 2001, the Bush administration immediately authorized the armed Predator program and the first drones arrived in Afghanistan on Oct. 7, 2001. President Bush signed a Memorandum of Notification creating a secret list of "High Value Targets" that the CIA was authorized to kill anywhere in the world without further presidential approval. The administration’s first known Predator strike occurred on Feb. 4, 2002 in Afghanistan, when a CIA Predator drone fired on a group they believed included Osama bin Laden. The targets, all killed, were civilians gathering scrap metal. The first known successful targeted killing occurred outside of a declared war zone, killing suspected USS Cole bombing mastermind Qaed Salim Sinan al-Harethi in Yemen on Nov. 4, 2002.
Since 9/11, over 95 % of all non-battlefield targeted killings have been conducted by drones. The CIA under the Bush Administration mostly engaged in "personality" strikes targeting known terrorists whose identities had been firmly established through intelligence, including visual surveillance and electronic and human intelligence. In 2008, the CIA began a policy of "signature strikes" against targets outside of named kill lists, targeting individuals based on their "pattern of life" or their suspicious daily behavior. In Pakistan in 2009 and 2010, as many as half of the 170 strikes were classified as signature strikes. Obama ordered around 280 drone strikes in Pakistan in his first presidential term alone, nearly seven times as many as in George W. Bush’s second term.
The United States operates drones with the tacit consent of the leaders of Pakistan, Yemen, Somalia, and Afghanistan. The parliaments and governing bodies of these countries, however, often issue public statements blasting the attacks, and public sentiment is strongly anti-drone.
Number of Strikes and Casualties
Different sources –both private and governmental– report different numbers for the number of strikes and combatant and civilian deaths. According to counts from the New America Foundation, Long War Journal, and The Bureau of Investigative Journalism, around 3500 militants in Pakistan, Afghanistan, Yemen, and Somalia have died in drone attacks. A meta-study of drone strikes concluded 8 % to 17 % of all people killed in drone strikes are civilians.
Since 2002, the United States has conducted a covert program to target and kill al Qaeda members based in Yemen. The first and only US drone strike of the Bush Administration in Yemen launched in 2002, and the strikes resumed in 2009 during President Barack Obama’s first term after a seven year hiatus. Between 2002 and Dec. 12, 2013, an estimated 57-82 drone strikes in Yemen resulted in the deaths of 268 to 790 "enemy", "extremist", or "militant" deaths, as well as 27-84 civilian deaths. 2012 was considered the deadliest year (approximately 42 airstrikes and 238 casualties). In 2013, the number of strikes and civilian deaths fell to 25 and 114 respectively following public awareness and outcry over the attacks.
Since 2004, the United States has conducted a covert program to target and kill al Qaeda and Taliban commanders based in Pakistan’s northwest tribal regions. 96 % of these strikes have taken place in the two regions of North and South Waziristan on the border with Afghanistan. Between 2004 and Nov. 29, 2013, an estimated 326-380 drone strikes in Pakistan resulted in 1620-2783 "enemy", "extremist", or "militant" deaths, as well as 156-951 civilian deaths. Pakistan told the United Nations in Oct. 2013 that at least 400 civilians have died from the attacks. 2010 was the deadliest year in Pakistan in both number of strikes and deaths. Both have declined sharply since.
The United States has conducted three to nine drone strikes against al Shabaab Islamic militants in Somalia between 2007 and Oct. 31, 2013, resulting in seven to 27 deaths, up to 16 of whom were civilians.
Public Outcry and Reform
In a Freedom of Information Act request filed on Jan. 13, 2010, the American Civil Liberties Union (ACLU) asked the government to disclose the legal and factual basis for its use of drones to conduct targeted killings abroad. In particular, they sought to find out when, where, and against whom drone strikes can be authorized, and how the United States ensures compliance with international laws relating to extrajudicial killings. A federal appeals court judge ruled on Mar. 15, 2013 that the CIA can no longer assert the "fiction" that it can’t reveal if it has a drone program, but the CIA has refused to release information for "national security" purposes.
In Sep. 2011, President Obama authorized the targeted killing of Anwar al-Awlaki, an American citizen tied to terrorist attacks. The Awlaki strike also killed another American, Samir Khan, who officials say was not intentionally targeted. A subsequent strike killed Mr. Awlaki’s 16-year-old American son, a death that officials say was an accident. A leaked white paper from the Department of Justice outlining the legal rationale for killing Americans affiliated with terrorist groups abroad claimed that an "individual’s [American] citizenship would not immunize him from a lethal operation".
Obama officially acknowledged drone strikes in Pakistan for the first time in a Jan. 2012. He openly referenced drone strikes in Yemen and Somalia for the first time in a June 2012 letter to Congress.
Under the stewardship of John O. Brennan, the president’s counter-terrorism adviser from Jan. 20, 2009 to Mar. 8, 2013, officials spent months discussing how to be more transparent about a program that was still officially secret and how to define its limits. Members of the Senate Intelligence Committee questioned Brennan on the use of drones for targeted killing during his confirmation hearing to become head of the CIA on Feb. 7, 2013, acknowledging "widespread debate" about the program. On Apr. 23, 2013, the Senate Judiciary Committee held a hearing on drone strikes, and heard from a range of witnesses on the constitutional and counter-terrorism implications of targeted killings.
On May 23, 2013, President Obama made a speech at National Defense University outlining his justification for the drone program and promising more transparency and tighter policies toward targeted killings. Obama stated in the speech that the United States would only take military action against a "continuing and imminent threat to the American people". The day before the speech, Obama issued "Presidential Policy Guidance" establishing five criteria that must be met before lethal action may be taken against a foreign target : "1) Near certainty that the terrorist target is present ; 2) Near certainty that non-combatants will not be injured or killed ; 3) An assessment that capture is not feasible at the time of the operation ; 4) An assessment that the relevant governmental authorities in the country where action is contemplated cannot or will not effectively address the threat to U.S. persons ; and 5) An assessment that no other reasonable alternatives exist to effectively address the threat to US persons".
On Apr. 23, 2015, the US government disclosed that two civilian aid workers being held hostage by al Qaeda in Pakistan were killed by a US drone strike back in January 2015. The incident renewed the debate over the CIA’s control over the drone program in Pakistan and US drone policy in general. The Obama administration and Senate leaders, including Sen. John McCain (R-AZ), expressed interest in transferring military drone control to the Department of Defense.
On Oct. 15, 2015, a collection of classified documents about the US drone program was released by an anonymous whistleblower and included revelations that as many as 90 percent of US drone killings in a five-month period were not the intended targets ; that there is a clear chain of command in determining targets and authorizing strikes ; and that unintended deaths from strikes were classified as "enemies killed in action" regardless of whether the casualties were civilians or combatants.

PRO US Drone Strikes
Drone strikes make the United States safer by decimating terrorist networks across the world. Drone attacks in Pakistan, Afghanistan, Yemen, and Somalia have killed upwards of 3500 militants, including dozens of high-level commanders implicated in organizing plots against the United States. According to President Obama, "dozens of highly skilled al Qaeda commanders, trainers, bomb makers and operatives have been taken off the battlefield. Plots have been disrupted that would have targeted international aviation, US transit systems, European cities, and our troops in Afghanistan. Simply put, these strikes have saved lives". David Rohde, a former New York Times reporter held hostage by the Taliban in Pakistan for several months in 2009, called the drones a "terrifying presence" for militants. On Nov. 1, 2013 drone strikes killed Pakistani Taliban leader Hakimullah Mehsud.
Drones kill fewer civilians, as a percentage of total fatalities, than any other military weapon. The traditional weapons of war -bombs, shells, mines, mortars- cause more unintended ("collateral") damage to people and property than drones, whose accuracy and technical precision mostly limit casualties to combatants and intended targets. Although estimates vary because of the secretive nature of the program, it is estimated that 174 to 1047 civilians have been killed in Pakistan, Yemen, and Somalia since the United States began conducting drone strikes abroad following the Sep. 11, 2001 attacks, roughly 8 %-17 % of all deaths from US drones. In comparison, in World War II, civilian deaths, as a percentage of total war fatalities, are estimated at 40 % to 67 %. In the Korean, Vietnam, and Balkan Wars, the percentages are approximately 70 %, 31 %, and 45 % respectively.
Drones make US military personnel safer. Drones are launched from bases in allied countries and are operated remotely by pilots in the United States, minimizing the risk of injury and death that would occur if ground soldiers and airplane pilots were used instead. Al Qaeda, the Taliban, and their affiliates often operate in distant and environmentally unforgiving locations where it would be extremely dangerous for the United States to deploy teams of special forces to track and capture terrorists. Such pursuits may pose serious risks to US troops including firefights with surrounding tribal communities, anti-aircraft shelling, land mines, improvised explosive devices (IEDs), suicide bombers, snipers, dangerous weather conditions, harsh environments, etc. Drone strikes eliminate all of those risks common to "boots on the ground" missions.
Drone strikes are cheaper than engaging in ground or manned aerial combat. With approximately $5 billion allocated for drones in the 2012 Department of Defense budget, America’s entire drone program constitutes only about 1 % of the entire annual military budget. In comparison, the military’s F-35 Joint Strike Fighter program alone cost the United States $9.7 billion in fiscal year 2012. US manned military attack aircraft cost anywhere from $18000 to $169000 per hour to operate -six to 42 times more than attack drones. Al Qaeda spent roughly half a million dollars to plan and execute the attacks on the United States on Sep. 11, 2001. In response, the United States spent roughly $2.2 trillion on funding manned air and ground wars in Afghanistan and Iraq and on homeland security costs in the following decade -over $4 million for every dollar al Qaeda spent.
Drone strikes are legal under international law. Article 51 of the UN Charter provides for a nation’s inherent right to self-defense when it has been attacked. The UN Special Rapporteur on extrajudicial, summary, or arbitrary executions has said that Article 51 applies if the targeted state agrees to the use of force in its territory, or the targeted group operating within its territory was responsible for an act of aggression against the targeting state where the host state is unwilling or unable to control the threat themselves. Afghanistan, Pakistan, Yemen, and Somalia have officially consented to US drone strikes within their countries because they are unable to control terrorist groups within their own borders. Former US State Department Legal Adviser and current Yale Professor of International Law Harold Koh says that a state engaged in an "armed conflict or in legitimate self-defense" is not required to provide targets with legal processing before using lethal force, and a country may target individuals in foreign countries if they are directly participating in hostilities or posing an imminent threat that only lethal force can prevent. The United States also has the right under international law to "anticipatory self-defense", which gives the right to use force against a real and imminent threat when the necessity of that self-defense is "instant, overwhelming, and leaving no choice of means, and no moment of deliberation".
Drone strikes are legal under US law. Presidential powers under Article II of the US Constitution allow the use of force against an imminent threat without congressional approval. Additionally, in 2001 Congress passed the Authorization for Use of Military Force (AUMF), authorizing armed conflict with al Qaeda and associated forces indefinitely. The AUMF states that the President is "authorized to use all necessary and appropriate force against those nations, organizations, or persons he determines planned, authorized, committed, or aided the terrorist attacks that occurred on September 11, 2001, or harbored such organizations or persons, in order to prevent any future acts of international terrorism against the United States by such nations, organizations or persons". The AUMF does not have a geographic boundary, and the Obama administration notes that al Qaeda militants far from the battlefield in Afghanistan are still engaged in armed conflict with the United States and therefore covered under the law.
Drones limit the scope and scale of military action. Since the 9/11 attacks, the main threats to US security are decentralized terrorist networks operating in countries around the world, not large countries fighting with massive air, ground, and sea armies. Invading Pakistan, Yemen, or Somalia to capture relatively small terrorist groups would lead the United States to expensive conflict, responsibility for destabilizing those governments, large numbers of civilian casualties, empowerment of enemies who view the United States as an occupying imperialist power, US military deaths, and other unintended consequences. America’s attempt to destroy al Qaeda and the Taliban in Afghanistan by invading and occupying the country resulted in a war that has dragged on for over 12 years. Using drone strikes against terrorists abroad allows the United States to achieve its goals at a fraction of the cost of an invasion in money, manpower, and lives.
Drone strikes are subject to a strict review process and congressional oversight. President Obama, in his "Presidential Policy Guidance" released on May 23, 2013, established five criteria that must be met before lethal action may be taken against a foreign target : "1) Near certainty that the terrorist target is present ; 2) Near certainty that non-combatants will not be injured or killed ; 3) An assessment that capture is not feasible at the time of the operation ; 4) An assessment that the relevant governmental authorities in the country where action is contemplated cannot or will not effectively address the threat to U.S. persons ; and 5) An assessment that no other reasonable alternatives exist to effectively address the threat to U.S. persons". Intelligence committees and "appropriate" members of Congress are briefed on every strike that America takes. Months before the targeting of American citizen Anwar al-Awlaki in Yemen, the Obama administration submitted information for comment to the Department of Justice, which conducted additional analysis to ensure that the action was consistent with US laws.
Drone strikes are carried out with the collaboration and encouragement of local governments, and make those countries safer. US drone strikes help countries fight terrorist threats to their own domestic peace and stability, including al Qaeda and the Taliban in Pakistan, al Shabaab in Somalia, al Qaeda in the Arabian Peninsula in Yemen, and al Qaeda in the Maghreb in Algeria and Mali. Yemen’s President, Abdu Rabbu Mansour Hadi, has openly praised drone strikes in his country, stating that the "electronic brain’s precision is unmatched by the human brain". In a 2008 State Department cable made public by Wikileaks, Pakistani Chief of Army Staff General Ashfaq Kayani asked US officials for more drone strikes, and in Apr. 2013 former Pakistani president Pervez Musharraf acknowledged to CNN that his government had secretly signed off on US drone strikes. In Pakistan, where the vast majority of drone strikes are carried out, drones have contributed to a major decrease in violence. The 41 suicide attacks in Pakistan in 2011 were down from 49 in 2010 and a record high of 87 in 2009, which coincided with an over ten-fold increase in the number of drone strikes.
The United States cannot risk falling behind the rest of the world in the development of drone technologies. More than 87 countries own some type of surveillance or attack drone, changing the way nations conduct war and threatening to begin a new arms race as governments scramble to counterbalance their adversaries. In 2010 Iran unveiled what it claimed was its first armed drone, and China unveiled 25 drone models. In 2011 there were 680 active drone development programs run by governments, companies, and research institutes around the world, compared with 195 in 2005. The Teal Group, a defense-consulting firm, estimated in June 2013 that the global market for the research, development, and procurement of armed drones would nearly double over the next decade from $5.2 billion annually to $11.6 billion. Insurgent groups are also moving to acquire this technology ; in 2011, Libyan opposition forces bought a drone during their attempt to overthrow dictator Moammar Gadhafi and Lebanese militant group Hezbollah claimed in 2012 that it flew an Iranian-made drone over Israel.
Drone pilots have a lower risk for post traumatic stress disorder (PTSD) than pilots of manned aircraft and other battlefield soldiers. Drone pilots suffer less than traditional pilots because they do not have to be directly present on the battlefield, can live a normal civilian life in the United States, and do not risk death or serious injury. Only 4 % of active-duty drone pilots are at "high risk for PTSD" compared to the 12 %-17 % of soldiers returning from Iraq and Afghanistan.
The majority of Americans support drone strikes. According to a July 18, 2013 survey by Pew Research, 61 % of Americans supported drone strikes in Pakistan, Yemen, and Somalia. Support spanned the political divide, including Republicans (69 %), independents (60 %), and Democrats (59 %). A Mar. 20, 2013 poll by the Gallup organization found that 65 % of Americans believed the US government should "use drones to launch airstrikes in other countries against suspected terrorists" and 74 % of Americans who "very" or "somewhat" closely follow news stories about drones supported the attacks. A May 28, 2013 Christian Science Monitor/TIPP poll found that 57 % of Americans supported drone strikes targeting "al Qaeda targets and other terrorists in foreign countries".
CON US Drone Strikes
Drone strikes create more terrorists than they kill. People who see their loved ones injured or killed in drone attacks become motivated to join actions against the United States. According to author Jeremy Scahill, the vast majority of militants operating in Yemen today are "people who are aggrieved by attacks on their homes that forced them to go out and fight". Support for al Qaeda in Yemen is "indigenously spreading and merging with the mounting rage of powerful tribes at US counterterrorism policy" as the drone strikes have "recruited thousands". The number of Al Qaeda in the Arabian Peninsula (AQAP) core members grew from 300 in 2009 (when US drone strikes resumed after a seven-year hiatus) to 700 in 2012, resulting in an exponential increase in the number of terrorist attacks in the region. Both the "Underwear Bomber", who tried to blow up an American airliner in 2009, and the "Times Square Bomber", who tried to set off a car bomb in New York City in 2010, cited drone strikes in Pakistan, Yemen, and Somalia as motivators for the plots.
Drone strikes target individuals who may not be terrorists or enemy combatants. President Obama’s policy of "signature strikes" allows the Central Intelligence Agency (CIA) and the military’s Joint Special Operations Command (JSOC) to target anyone who fits a specific terrorist profile or engages in behavior the US government associates with terrorists, regardless of whether or not they have been conclusively identified by name as enemy combatants. Classified documents leaked in Oct. 2015 showed that in one five-month period of drone strikes in Afghanistan, as many as 90 percent of those killed were not the intended targets, and that those unintended deaths were classified as "enemies killed in action" regardless of whether they were civilians or combatants. At the height of the drone program in Pakistan in 2009 and 2010, as many as half of the strikes were classified as signature strikes. According to top-secret intelligence reports reviewed by McClatchy Newspapers, drone operators are not always certain of who they are killing "despite the administration’s guarantees of the accuracy of the CIA’s targeting intelligence". The CIA and JSOC target "associated forces", "foreign fighters", "suspected extremists", and "other militants", but do not publicly reveal whether those killed are actively involved in terrorism against the United States. In two sets of classified documents obtained by NBC News describing 114 drone strikes in Pakistan and Afghanistan between Sep. 3, 2010 and Oct. 30, 2011, 26 strikes targeted "other militants", meaning that the CIA could not conclusively determine the affiliation of those killed.
Drone strikes kill large numbers of civilians and traumatize local populations. According to a meta-study of drone strikes, between 8 % to 17% of all people killed in drone strikes are civilians. Since the United States began conducting drone strikes abroad following the Sep. 11, 2001 attacks, it is estimated that between 174 and 1047 civilians have been killed in Pakistan, Yemen, and Somalia. According to 130 interviews with victims and witnesses of drone strikes by researchers from Stanford and New York University, people who live in the affected areas experience harm "beyond death and physical injury" and "hear drones hover 24 hours a day", and live with the fear that a strike could occur at any moment of the day or night. According to Clive Stafford Smith, Director of human rights organization Reprieve, "an entire region is being terrorized by the constant threat of death from the skies. Their way of life is collapsing : kids are too terrified to go to school, adults are afraid to attend weddings, funerals, business meetings, or anything that involves gathering in groups". Yemeni tribal sheik Mullah Zabara says "we consider the drones terrorism. The drones are flying day and night, frightening women and children, disturbing sleeping people. This is terrorism".
Drone strikes mostly kill low-value targets who are not significant threats to US safety and security. Drones kill very few "high-value" targets with alleged leadership roles in al Qaeda or anti-US Taliban factions. Reuters reported that of the 500 "militants" the CIA believed it had killed with drones between 2008 and 2010, only 14 were "top-tier militant targets", and 25 were "mid-to-high-level organizers" of al Qaeda, the Taliban, or other hostile groups. The CIA had killed around 12 times more low-level fighters than mid-to-high-level during that same period. According to the New America Foundation, from 2004 to 2012 an estimated 49 "militant leaders" were killed in drone strikes, constituting "2 % of all drone-related fatalities".
Drone strikes violate international law. Under international humanitarian law, the targeted individual must be directly participating in hostilities with the United States. Under international human rights law, the targeted individual must pose an imminent threat that only lethal force can prevent. Simply being suspected of some connection to a "militant" organization —or, under the CIA’s policy of "signature" drone strikes, fitting the profile of a terrorist in an area where terrorists are known to operate– is not legally sufficient to make someone a permissible target for killing. Article 6(1) of the International Covenant on Civil and Political Rights, a multilateral treaty adopted by the United Nations, states that "no one shall be arbitrarily deprived of his life", even in times of armed conflict. Article 2(4) of the UN Charter prohibits the threat or use of force by one state against another, with the exceptions of (1) the consent of the host state, and (2) when the use of force is in self-defense in response to an armed attack or an imminent threat, where the host state is unwilling or unable to take appropriate action. Members of militant groups with which the United States is not in an armed conflict are therefore not lawful targets. Amnesty International says drone strikes can be classified as "war crimes" or illegal "extrajudicial executions".
Drone strikes are secretive, lack sufficient legal oversight, and prevent citizens from holding their leaders accountable. Drones are used in conflicts where war is not openly declared and authorized by Congress, allowing the executive branch to have nearly unlimited power over secret wars across the world. Strikes by the CIA (responsible for approximately 80 % of all US drone strikes worldwide) are classified under US law as Title 50 covert actions, defined as "activities of the United States Government... where it is intended that the role... will not be apparent or acknowledged publicly". As covert operations, the government cannot legally provide any information about how the CIA conducts targeted killings. The CIA has yet to officially acknowledge its drone programs anywhere in the world, let alone describe the rules and procedures for compliance with US and international law. The administration only gives drone program details to members of Congress whom it deems "appropriate", and it has sought to prevent judicial review of claims brought in US courts by human rights groups seeking accountability for potentially unlawful killings.
Drone strikes violate the sovereignty of other countries. Strikes are often carried out without the permission and against the objection of the target countries. Pakistan’s foreign ministry on June 4, 2012 called drone strikes "illegal" and said they violated the country’s sovereignty. On Oct. 22, 2013, Pakistani Prime Minister Nawaz Sharif said that the "use of drones is not only a continued violation of our territorial integrity but also detrimental to our resolve at efforts in eliminating terrorism from our country... I would therefore stress the need for an end to drone attacks". The United Nations’ Human Rights Chief, Special Rapporteur on counter-terrorism and human rights, and Special Rapporteur on extrajudicial, summary, or arbitrary executions have all called US drone strikes a violation of sovereignty, and have pressed for investigations into the legality of the attacks. In a July 18, 2013, 39-country survey by Pew Research, only six countries approved of US drone strikes in Pakistan, Yemen, and Somalia.
Drone strikes allow the United States to become emotionally disconnected from the horrors of war. According to Keith Shurtleff, US army chaplain and ethics instructor, as soldiers are "physically and psychologically removed from the horrors of battle and see the enemy not as humans but as blips on a screen, there is a danger of losing the deterrent to war that its horrors normally provide". Without this deterrent, it becomes easier for the United States to start new battles and extend existing conflicts indefinitely. Drone pilot Colonel D. Scott Brenton, in a July 29, 2012 interview with the New York Times, acknowledged the disconnect of fighting a "telewar with a joystick and a throttle" thousands of miles away from the battlefield, then driving home to have dinner with his family. "I feel no emotional attachment to the enemy", he said. "I have a duty, and I execute the duty. No one in my immediate environment is aware of anything that occurred". According to Representative Lynn Woolsey (D-CA), it’s "such a trend to dehumanize warfare. It’s machines and computers doing the job... [but this] is not video games, these are real people and it’s real death and we’re making real enemies around the world by continuing with the drone strikes".
US drone strikes give cover for other countries to engage in human rights abuses. America’s use of drones in foreign countries makes it all but impossible to demand that other countries self-impose limitations on their own drone use. Just as the United States justifies its drone strikes with the argument that it is at war with al Qaeda and its affiliates, drone strikes may be used by other countries to target what they consider terrorists and what Americans would consider as cover for human rights abuses against non-combatants. China could justify drone strikes against Tibetan separatists in India, Russia could justify attacks against rebels in Chechnya, or Turkey could target Kurdish insurgents in Iraq. Philip Alston, former UN Special Rapporteur on extrajudicial, summary or arbitrary executions, said that an "arms race" spurred by the widespread use of drones by the US government is already well under way.
Drone strikes are extremely unpopular in the affected countries. General Stanley McChrystal, former leader of the US military in Afghanistan, says that the "resentment created by American use of unmanned strikes... is much greater than the average American appreciates. They are hated on a visceral level, even by people who’ve never seen one or seen the effects of one". 76 % of residents in the Federally Administered Tribal Areas (FATA) of northwestern Pakistan (where 96 % of drone strikes in the country are carried out) oppose American drone strikes. 16 % think these strikes accurately target militants and 48 % think they largely kill civilians. Only 17 % of Pakistanis back American drone strikes against leaders of extremist groups, even if they are conducted in conjunction with the Pakistani government. On three separate occasions, Pakistan’s Parliament has voted to condemn the attacks and end the country’s cooperation with the CIA, and leaders in the FATA voted on Nov. 4, 2013 to block NATO supply lines unless the United States stops its drone strikes. On Dec. 16, 2013, Yemen’s parliament passed a motion calling for the United States to end its drone program in the country after a wedding convoy of 11 to 15 people were killed by a US drone strike.
Many drone operators have emotional and psychological stress. A study from the US Air Force’s School of Aerospace Medicine, Department of Neuropsychiatry, found that drone pilots, in addition to witnessing traumatic combat experiences, face several unique problems : lack of a clear demarcation between combat and personal/family life ; extremely long hours with monotonous work and low staffing ; "existential conflict" brought on by the guilt and remorse over being an "aerial sniper" ; and social isolation during work, which could diminish unit cohesion and increase susceptibility to PTSD. According to a study of 709 drone pilots by the Armed Forces Health Surveillance Center, approximately 8.2 % reported at least one adverse mental health outcome, most commonly disorders related to adjusting to re-entry into civilian society, depression, and relationship problems.
