Krauthammer generally agrees that the Cold War's end means the United States should eschew "teacup wars." But he says that humanitarian reasons may require the United States to intervene where it has no vital interest--if and only if there is genocide. "Only the ultimate crime justifies the ultimate sanction (military intervention)." Krauthammer, for example, supported intervention in Somalia because rebels were intentionally causing mass starvation. But he has rejected intervention in Bosnia and Kosovo because "expulsion is not extermination."
