Below Glenn Greenwald offers a great counter the whole "Bush/Cheney kept us safe" meme. I always hated that notion because it relies on what we don't know, and it pretends that 9/11 happened under some other guys watch. Why do these cats get a free pass for the most catastrophic act of terror ever perpetrated on US soil?
But Greenwald makes a better point. If one concedes that that Bush/Cheney torture regime kept us safe, one must also conclude that Bill Clinton kept us safe, since the first WTC attack happened under his watch, and their were no more after it. This is really the only leg Bush-defenders have to stand on--"he kept us safe." But the last guy did that, and he foibles, while unfortunate, certainly don't rise to the "Heckuva job Brownie" level.
