DEPARTMENT OF JUSTICE WHITE PAPER
Lawfulness of a Lethal Operation Directed Against a U.S. Citizen Who Is a Senior Operational Leader of Al-Qa’ida or An Associated Force
This white paper sets forth a legal framework for considering the circumstances in which the U.S. government could use lethal force in a foreign country outside the area of active hostilities against a U.S. citizen who is a senior operational leader of al-Qa’ida or an associated force[1] of al-Qa’ida—that is, an al-Qa’ida leader actively engaged in planning operations to kill Americans. The paper does not attempt to determine the minimum requirements necessary to render such an operational lawful; nor does it assess what might be required to render a lethal operation against a U.S. citizen lawful in other circumstances, including an operation against enemy forces on a traditional battlefield or an operation against a U.S. citizen who is not a senior operational leader of such forces. Here the Department of Justice concludes only that where the following three conditions are met, a U.S. operation using lethal force in a foreign country against a U.S. citizen who is a senior operational leader of al-Qa’ida or an associated force would be lawful: (1) an informed, high-level official of the U. S. government had determined that the targeted individual poses an imminent threat of violent attack against the United States; (2) capture is infeasible, and the United States continues to monitor whether capture becomes feasible; and (3) the operation would be conducted in a manner consistent with applicable law of war principles. This conclusion is reached with recognition of the extraordinary seriousness of a lethal operation by the United States against a U.S. citizen, and also of the extraordinary seriousness of the threat posed by senior operational al-Qa’ida members and the loss of life that would result were their operations successful.
The President has authority to respond to the imminent threat posed by al-Qa’ida and its associated forces, arising from his constitutional responsibility to protect the country, the inherent right of the United States to national self defense under international law, Congress’s authorization of the use of all necessary and appropriate military force against this enemy, and the existence of an armed conflict with al-Qa’ida under international law. Based on these authorities, the President may use force against al-Qa’ida and its associated forces. As detailed in this white paper, in defined circumstances, a targeted killing of a U.S. citizen who has joined al-Qa’ida or its associated forces would be lawful under U.S. and international law. Targeting a member of an enemy force who poses an imminent threat of violent attack to the United States is not unlawful. It is a lawful act of national self defense. Nor would it violate otherwise applicable federal laws barring unlawful killings in Title 18 or the assassination ban in Executive Order No. 12333. Moreover, a lethal operation in a foreign nation would be consistent with international legal principles of sovereignty and neutrality if it were conducted, for example, with the consent of the host nation’s government or after a
- ↑ An associated force of al-Qa’ida includes a group that would qualify as a co-belligerent under the laws of war. See Hamlily v. Obama, 616 F. Supp. 2d 63, 74–75 (D.D.C. 2009) (authority to detain extends to “ ‘associated forces,’ ” which “mean ‘co-belligerents’ at that term is understood under the laws of war”).
