United States, and who wished to challenge the government’s assertion that he was part of enemy forces. The Court explained that the “process due in any given instance is determined by weighing ‘the private interest that will be affected by the official action’ against the Government’s asserted interest, ‘including the function involved’ and the burdens the Government would face in providing greater process.” Hamdi, 542 U.S. at 529 (plurality opinion) (quoting Mathews v. Eldridge, 424 U.S. 319, 335 (1976)). The due process balancing analysis applied to determine the Fifth Amendment rights of a U.S. citizen with respect to law-of-war detention supplies the framework for assessing the process due a U.S. citizen who is a senior operational leader of an enemy force planning violent attacks against Americans before he is subjected to lethal targeting.
In the circumstances considered here, the interests on both sides would be weighty. See Hamdi, 542 U.S. at 529 (plurality opinion) (“It is beyond question that substantial interests lie on both sides of the scale in this case.”). An individual’s interest in avoiding erroneous deprivation of his life is “uniquely compelling.” See Ake v. Oklahoma, 470 U. S. 68, 178 (1985) (“The private interest in the accuracy of a criminal proceeding that places an individual’s life or liberty at risk is almost uniquely compelling.”). No private interest is more substantial. At the same time, the government’s interest in waging war, protecting its citizens, and removing the threat posed by members of enemy forces is also compelling. Cf. Hamdi, 542 U.S. at 531 (plurality opinion) (“On the other side of the scale are the weighty and sensitive governmental interests in ensuring that those who have in fact fought with the enemy during a war do not return to battle against the United States.”). As the Hamdi plurality observed, in the “circumstances of war,” “the risk of erroneous deprivation of a citizen’s liberty in the absence of sufficient process… is very real,” id. at 530 (plurality opinion), and, of course, the risk of an erroneous deprivation of a citizen’s life is even more significant. But, “the realities of combat” render certain uses of force “necessary and appropriate,” including force against U.S. citizens who have joined enemy forces in the armed conflict against the United States and whose activities pose an imminent threat of violent attack against the United States—and “due process analysis need not blink at those realities.” Id. at 531 (plurality opinion). These same realities must also be considered in assessing “the burdens the Government would face in providing greater process” to a member of enemy forces. Id. at 529, 531 (plurality opinion).
In view of these interests and practical considerations, the United States would be able to use lethal force against a U.S. citizen, who is located outside the United States and is an operational leader continually planning attacks against U.S. persons and interests, in at least the following circumstances: (1) where an informed, high-level official of the U. S. government has determined that the targeted individual poses an imminent threat of violent attack against the United States; (2) where a capture operation would be infeasible—and where those conducting the operation continue to monitor whether capture becomes feasible; and (3) where such an operation would be conducted consistent with applicable law of war principles. In these circumstances, the “realities” of the conflict and the weight of the government’s interest in protecting its citizens from an imminent attack are such that the Constitution would not require the government to provide further process to such a U.S. citizen before using lethal force. Cf. Hamdi, 542
