This is supposedly a quote from Bush a year BEFORE launching his attack- even though publicly he claimed right up to the end and even now that he tried every diplomatic avenue possible to avoid military confrontation.

The president also claimed on Tuesday that, "in Iraq, there was a lot of diplomacy that took place before there was any military action."4 But in fact, Time reported a meeting from March 2002, a full year before the war began, in which Bush "showed little interest in debating what to do about Hussein," and told a group of Senators, "[expletive] Saddam. We're taking him out."5 Weeks later, Vice President Cheney separately told a group of Senators that, "The question was no longer if the U.S. would attack Iraq, he said. The only question was when."6 But months later, the president was still telling the public, "I hope this will not require military action."
