There is absolutely no doubt about Bush/Cheny et al being among the greatest war criminals of all time - lying to get us into a war whose real intent was resource theft and expansion of the empire's overseas network of bases, and torture including that which went beyond waterboarding, etc. For these crimes they deserve new ring in Dante's Inferno.
But is Obama, for whom we had such high hopes, sliding down or already on the same morally-bankrupt path. Decade's ago a Republican president made it illegal to assassinate foreign officials, a practice until then widely practiced by the CIA. Well just what should we call the killing of an Al Quaeda member, or even suspected terrorists, from 10,000 ft via a predator drone controlled by an operator using a joystick thousands of miles away? Is this less somehow less reprehensible - even though 10's of nearby innocents may also perish - than death by an exploding cigar or an assassin's bullet? What kind of nation deems it acceptable - always in the name of promoting peace and democracy - to conduct such operations worldwide? And should our current leader - who has expanded these killings initiated under Bush - be held less culpable than the Bush crime family?
