Powell and Rice were culpable (look up the word if you don't know its meaning) for the deaths of every American (and many Iraqis) for fear mongering during the effort to justify the invasion of Iraq:
"Condi Rice discusses Iraqi President Saddam Hussein's nuclear capabilities with Wolf Blitzer on Jan, 10th, 2003 and she infamously said: "there will always be some uncertainty about how quickly he can acquire nuclear weapons. But we don't want the smoking gun to be a mushroom cloud.""
Condoleezza Rice: 'Don't Want Smoking Gun To Be A Mushroom Cloud.'
And Powell's dog and pony show before the UN and the world:
But those were not criminal acts, those we can reserve for Bush and Cheney and Rumsfeld!
