On 9/11, Cheney immediately thought of the worst possible scenario: What if this had been done with WMDs? It has haunted him ever since - for good and even noble reasons. This panic led him immediately to think of Saddam. But it also led him to realize that our intelligence was so crappy that we simply didn't know what might be coming. That's why the decision to use torture was the first - and most significant - decision this administration made. It is integral to the intelligence behind the war on terror. And Cheney's bizarre view of executive power made it easy in his mind simply to break the law and withdraw from Geneva because torture, in his mind, was the only weapon we had.
