The lively and ongoing debate at Opinio Juris on the legal aspects of the "war on terror" is getting a whole lot livelier now that John B. Bellinger III, Condi Rice's top legal advisor, has entered the ring with a series of lengthy posts defending the administration's conduct. In response to the routine criticisms lobbed at the administration for its seemingly indefinite detention of suspected terrorists, Bellinger argues that so long as we are engaged in distinct, parallel wars with the Taliban and Al Qaeda, detaining "enemy combatants" is appropriate. This raises the obvious question: When do these wars end? The responding bloggers, including the venerable David Sloss and Eric Posner, are grilling Bellinger on this question, judicial review of the detentions, his own role, and related legal issues in the war on terror. The entire debate, a rare instance of the Bush administration engaging its critics seriously and at length, is not to be missed.
