"He made a decision based on faulty information just like everybody else did at the time."
Not that I want to go over this again, and again. But this line is just ---That which is odiferous and causeth plants to grow---. With every passing day it becomes more and more apparent that Cheney had cherry-picked intelligence stovepiped to the administration from certifiably shaky sources ("Curveball", Chalabi, Ibn al-Shaykh al-Libi). This war was then marketed to the american public by the W.H.I.G. (White House Iraq Group) and the false charges against Saddam were trumped up in the pages of the New York Times, Washington Post, etc..through journalists friendly to the administration (Judith Miller, et al). Immediately afterward, the 24-7 news channels referenced these false claims and repeated them ad infinitum. So much so that, in some polls, a huge chunk of American thought Saddam has a direct hand in 9/11!!
Opponents/critics of the war and it's flimsy justifications, both inside and outside the administration, were handily crushed (Plame, Gen. Sinseki, etc) and the chilling effect kept the intelligence community at bay, at least until recently.
Bush got his "War of Choice". Whether he knew the intel was false beforehand is still being investigated, but one thing is for certain, there is way more evidence pointing to the fact that he (and his administration) knew the intel was flimsy and/or false, than there is evidence that he was an innocent bystander, dubbed by a lackadaisical intelligence community, or swarthy tin-pot dictator in the middle east.
