The killing of Osama bin Laden is an instance of a much more general policy pursued by the United States and its allies – the targeted killing of named individuals in the war against terrorism and against various insurgencies in Iraq and Afghanistan. In the midst of American celebration of the fact that al-Qaida has lost its charismatic leader, it is worth getting clear about targeted killing in general, i.e. about the legality and the desirability of a policy of this kind. Targeted killings are of two kinds. The first involves killing people who are actually engaged in carrying out terrorist acts – planting a bomb or preparing someone for a suicide bombing. The second involves the elimination of high-profile individuals whose names appear on a special list of active commanders and participants in terrorism or insurgency. These killings are part of a strategy of disruption and decapitation directed against terrorist organisations.
