Targeted killings by Israel Defense Forces Israeli targeted killings , by the Israel Defense Forces ( IDF ) also called targeted prevention ( ' ) or focused foiling , is the term used in the course of the Israeli - Palestinian conflict to describe the targeted killing of persons accused of carrying out or planning attacks against Israeli targets in the Occupied Palestinian Territory ( OPT ) and / or inside Israel . The Israeli army maintains that it pursues such military operations to prevent imminent attacks when it has no discernible means of making an arrest or foiling such attacks by other methods . On December 14 , 2006 , the Supreme Court of Israel ruled that targeted killing is a legitimate form of self - defense against terrorist s , and outlined several conditions for its use . Strike methods and well known targeted killings . Strike methods . Many strikes have been carried out by Israeli Air Force attack helicopter s ( mainly the AH - 64 Apache ) that fire guided missile s toward the target , after the Shin Bet supplies intelligence for the target . Sometimes , when heavier bombs are needed , the strike is carried out by F - 16 warplanes . Other strategies employ strike teams of Israeli intelligence or military operatives . These operatives infiltrate areas known to harbor targeted individuals , and eliminate their assigned targets with small arms fire or use of explosive s . Sniper s have also been utilized , as was in the case of Dr Thabet Thabet in 2001 . Unmanned aerial vehicle are used for the strikes as well . Regardless of the method used , intelligence on targets is critical . As regards helicopter strikes , orbiting UAV s or unmanned drones , linked to intelligent monitoring and eavesdropping systems , provide targeting data to assigned strike aircraft . Special care is taken to minimize civilian casualties , and sometimes strikes were aborted if the civilian presence near the target was too large to be politically acceptable . Targeted killings . Some of the targeted killings by the Israeli military were Hamas leaders Mahmoud Adani ( February 2001 ) , Jamil Jadallah ( November 2001 ) , Salah Shahade ( July 2002 ) , Sheikh Ahmed Yassin ( March 2004 ) , Abdel Aziz al - Rantissi ( April 2004 ) and Adnan al - Ghoul ( October 2004 ) , all targeted in the Al - Aqsa Intifada . While the term " targeted killing " usually describes airborne attacks , Israeli security forces have killed top Palestinian militant s in the past by other means , although this has never been confirmed officially . Some of the known operations include : Civilian casualty ratio . According to the Israeli Human Rights organization B ' Tselem , which uses data independent of the Israeli military , Israeli targeted killings claimed 425 Palestinian lives between September 2000 and August 2011 . Of these , 251 persons ( 59 . 1 percent ) were the targeted individuals and 174 ( 40 . 9 percent ) were civilian bystanders . This implies a ratio of civilians to targets of 1 : 1 . 44 during the whole period . The civilian casualty ratio of the targeted killings was surveyed by " Haaretz " military journalist Amos Harel . In 2002 and 2003 , the ratio was 1 : 1 , meaning one civilian killed for every target killed . Harel called this period " the dark days " because of the relatively high civilian death toll as compared to later years . He attributed this to an Israeli Air Force ( IAF ) practice of attacking targets even when they were located in densely populated areas . While there were always safety rules , argued Harel , these were " bent " at times in view of the target ' s importance . According to Harel , the civilian casualty ratio dropped steeply to 1 : 28 in late 2005 , meaning one civilian killed for every 28 targets killed . Harel credited this drop to the new IAF chief Eliezer Shkedi ' s policies . The ratio rose again in 2006 to 1 : 10 , a fact that Harel blamed on " several IAF mishaps " . However , in 2007 and 2008 the ratio dropped to a level of less than 1 : 30 , or 2 – 3 percent of the total casualties being civilian . Figures showing an improvement from 1 : 1 in 2002 to 1 : 30 in 2008 were also cited by " Jerusalem Post " journalist Yaakov Katz . Professor Alan Dershowitz of Harvard Law School stated that the 2008 figure of 1 : 30 represents the lowest civilian to combatant casualty ratio in history in the setting of combating terrorism . Dershowitz criticized the international media and human rights organizations for not taking sufficient note of it . He also argued that even this figure may be misleading because not all civilians are innocent bystanders . In October 2009 , Dershowitz stated that the ratio for Israel ' s campaign of targeted killings of terrorists stood at 1 civilian for every 28 targets . He argued that " this is the best ratio of any country in the world that is fighting asymmetrical warfare against terrorists who hide behind civilians . It is far better than the ratio achieved by Great Britain and the United States in Iraq or Afghanistan , where both nations employ targeted killings of terrorist leaders . " Regarding the practices which might have led to this record and the reasons the civilian death rate nevertheless remained above zero , Dershowitz cited Col . Richard Kemp ' s statements on the Gaza War : [ f ] rom my knowledge of the IDF and from the extent to which I have been following the current operation , I don ’ t think there has ever been a time in the history of warfare when any army has made more efforts to reduce civilian casualties and deaths of innocent people than the IDF is doing today in Gaza . . . Hamas , the enemy they have been fighting , has been trained extensively by Iran and by Hezbollah , to fight among the people , to use the civilian population in Gaza as a human shield . . . Hamas factor in the uses of the population as a major part of their defensive plan . So even though as I say , Israel , the IDF , has taken enormous steps . . . to reduce civilian casualties , it is impossible , it is impossible to stop that happening when the enemy has been using civilians as human shields . However , in a July 2011 article published in the " Michigan War Studies Review " , " Targeted Killings : A Modern Strategy of the State " , A . E . Stahl and William F . Owen wrote that casualty ratios and death counts in general should be considered skeptically . Stahl and Owen state : " A caveat : reported death counts and casualty ratios should be approached with skepticism . Statistics are too easy to manipulate for political purposes , vitiating arguments based on them . " Controversies relating to the strategy of targeted killings . The exact nature of the proof required by the Israelis for the killings is classified , as it involves clandestine military intelligence - oriented means and operational decisions . However all Mossad targeted killings must have the approval of the Prime Minister . Rather than being a part of a published justice system executed by lawyers and judges . International law provides two distinct normative paradigms which govern targeted killings in situations of law enforcement and the conduct of hostilities . As a form of individualized or surgical warfare , the method of targeted killing requires a " microscopic " interpretation of the law regulating the conduct of hostilities which leads nuanced results reflecting the fundamental principles underlying international humanitarian law . Any targeted killing not directed against a legitimate military target remains subject to the law enforcement paradigm , which imposes extensive restraints on the practice and even under the paradigm of hostilities , no person can be lawfully liquidated without further considerations . Proponents of targeted killings . Proponents of the strategy argue that targeted killings are within the rules of war . They contend they are a measured response to terrorism , that focuses on actual perpetrators of militant attacks , while largely avoiding innocent casualties . They point out that targeted killings prevented some attacks against Israeli targets , weakened the effectiveness of militant groups , kept potential bomb makers on the run , and served as deterrence against militant operations . They also argue that targeted killings are less harmful toward Palestinian non - combatants than full - scale military incursion into Palestinian cities . The IDF claims that targeted killings are only pursued to prevent future terrorism acts , not as revenge for past activities as such they are not extrajudicial . The IDF also claims that this practice is only used when there is absolutely no practical way of foiling the future acts by other means ( e . g . , arrest ) with minimal risk to its soldiers or civilians . The IDF also claims that the practice is only used when there is a certainty in the identification of the target , in order to minimize harm to innocent bystanders . They argue that because many of the Palestinians who have targeted Israel over the years have enjoyed the protection of Arab governments , extraditing them for trial in Israel has often proved impossible . They argue that Israeli governments have long used targeted killings as a last resort , when there were no peaceful options for bringing suspected terrorists to account . In a 2010 article in Infinity Journal , it was argued that targeted killings are a strategy that entails " limited , force in support of policy " and that the strategy has proven to work , albeit within specific contexts . The context of the " Infinity Journal " article related specifically to Hamas ' calls for ceasefires and " calms " in 2004 after the majority of their leadership had been successfully targeted by Israeli forces . According to the article , " Targeted Killings Work " , Israeli targeted killings throughout " the 2000 – 2005 armed rebellion represented a successful strategy " because " the tactics never undermined Israeli policy enough to alter Israel ’ s overall political objectives " and because Hamas ' will to continue with armed violence was temporarily broken . Opponents of targeted killings . Opponents of Israel ' s policy of targeted killings claim that it violates the laws of war . They feel these targeted killings are extrajudicial and feel that this violates the norms and values of a democratic society . Some question whether the IDF claims of no other way is correct and debate the secret process of IDF deliberations . Moreover many feel that actual injury and death of innocent bystanders , unintended as they may be , makes a strong claim against targeted killings . Some hold that such strikes do not reduce terrorism , but encourage more recruits to join militant factions , and are a setback to the Middle East peace process . In 2003 , 27 Israeli Air Force pilots composed a letter of protest to the Air Force commander Dan Halutz , announcing their refusal to continue and perform attacks on targets within Palestinian population centers , and claiming that the occupation of the Palestinians " morally corrupts the fabric of Israeli society " . After more than 30 signed , 4 later recanted . One , an El Al pilot , was threaten with dismissal and another lost his civilian job . Rule of law . In 2006 , Israel ' s Supreme Court rejected a petition to declare targeted killings illegal . The court recognized that some killings violated international law , but the legality of individual operations must be assessed on a " case by case basis " . It also said its decision that caution was needed to prevent civilian casualties . " Innocent civilians should not be targeted , " it said . " Intelligence on the ( targeted ) person ' s identity must be carefully verified . " The court also allowed for the possibility of compensation claims from civilians . Defenders of this practice argue that the Palestinian National Authority has not lived up to its treaty agreements to crack down on militants and has even aided them in escaping Israeli authorities . As such in a legal opinion , Israeli attorney general Elyakim Rubinstein wrote : " The laws of combat which are part of international law , permit injuring , during a period of warlike operations , someone who has been positively identified as a person who is working to carry out fatal attacks against Israeli targets , those people are enemies who are fighting against Israel , with all that implies , while committing fatal terror attacks and intending to commit additional attacks — all without any countermeasures by the PA . " Gal Luft of the Institute for the Analysis of Global Security has argued that because the Palestinian National Authority is not a state , and because few governments recognize Hamas ' control in Gaza , the Israeli - Palestinian conflict is not bound by the set of norms , rules , and treaties regulating other state conflicts . John Podhoretz has written for the New York Post that if the conflict were between states , targeted killing would be in accordance with the Fourth Geneva Convention ( ) which reads : “ The presence of a protected person may not be used to render certain points or areas immune from military operations . ” Podhoretz therefore argues that international law explicitly gives Israel the right to conduct military operations against military targets under these circumstances . Opponents of Israeli targeted killings , among them human rights groups and members of the international community including Britain , the European Union , Russia , France , India , China , Brazil , South Africa and all Arab States , have stated that targeted killings violate international laws and create an obstruction to the peace process . Authors Howard Friel , Richard Falk , and Palestinian representatives to the United Nations Security Council regard targeted killings as extrajudicial killing , and argue that it is a rejection of the rule of law and due process . They defend that in international law assassination was outlawed in both the 1937 convention of for the Prevention and Repression of Terrorism and the 1973 New York convention . Israeli public support or opposition towards targeted hits . Targeted killings are largely supported by Israeli society . A poll published by " Maariv " newspaper in July 2001 found that 90 percent of Israeli public support the practice . Effectiveness of Palestinian attacks and the Israeli response . Statistics on hit policy effectiveness in reducing attacks . While it is said that the IDF ' s reprisal targeted killing policy has reduced the effectiveness of Palestinian attacks , it increased the number of HAMAS attacks between 2001 and 2005 . Although the total number of Hamas operations increased , deaths resulting from such attacks plunged from a high of 75 in 2001 , to 21 in 2005 . For example , after the targeting of Yassin in 2004 there was a severe increase in the number of attacks carried out ( an increase of 299 attacks ) yet there were only 4 suicide attacks , a decrease from the previous year . According to the report by A . E . Stahl , a Research Fellow at the International Institute for Counter - Terrorism , following the targeted operation against Yassin , " Suicide terrorism by Hamas decreased by ﬁve and the total number of deaths caused by suicidal terrorism also declined by 19 . Though the total number of attacks increased the total number of deaths decreased severely : attacks rose by 299 but deaths fell by 27 . " Targeted killings may also have been effective , as is witnessed in the political reactions of HAMAS . Stipulations were demanded by HAMAS in the form of " Tahadiyehs " and " Hudnas " . It seems HAMAS was “ forced to operate at reduced levels of efficiency ” and was eventually forced to agree to a " Tahadiyeh " , likely due to targeted killings . Hits versus other intervening factors in analyzing effectiveness of Israeli strikes . There are several practical reasons why calculated hits may weaken the effectiveness of terrorist activities . Targeted killings physically eliminate skilled terrorists , bomb makers , forgers , recruiters and other operatives , who need time to develop expertise . Targeted hits also disrupt the opponent ' s infrastructure and organization , and cause immense stress on individual leaders and fighters , who must constantly move , switch locations and hide . This reduces the flow of information in the terrorist organization and reduces its effectiveness . Targeted killings may also serve as a demoralizing agent . Targeted individuals cannot visit their wives , children , relatives or families without severe risk , and may even shirk their names coming out in public for fear of liquidation as Israeli killings of Hamas leaders Ahmed Yassin and Abdelaziz Rantisi caused Hamas to not publicly identify their replacement , a necessary step to secure his survival . Continual diplomatic pressure against the Israeli policy , and the announcement of periodic unilateral cease fires at various times by Hamas , are seen by some as further proof of the policy ' s efficacy .
