I think anything is possible in the coming four years including not only the disbarment of the Bush WH, Defense and Justice attorneys. But, if Obama actually signs the International Criminal Court treaty, then we could see former administration officials tried for "war crimes". It's coming.
Yes, I know about Tony West and all the rest hate-America-first defense lawyers Obama stuck in the DoJ and DoD.
Of course, Obama is continuing many of these policies, even if under the radar. So he might be a target as well.
