Bush still thought in 2006 that Iraq had WMD.

Bush, for his part, was not disposed to second-guessing. Througout 2006, he read historical texts relating to Lincoln, Churchill, and Truman — three wartime leaders, the latter two of whom left office to something less than public acclaim. History would acquit him, too. Bushwas confident of that, and of something else as well. Though it was not the sort of thing one could say publicly anymore, the president still believed that Saddam had possessed weapons of mass destruction. He repeated this conviction to Andy Card all the way up until Card’s departure in April 2006, almost exactly three years after the Coalition had begun its fruitless search for WMDs. [p. 388]

In 2006. Long after even the diehard Fox viewers had reluctantly given up on the notion. Hell, he's probably still thinking it.

Someone this delusional is going to have no problem thinking that bombing Iran will solve all his problems. He's listening to nutjobs like Michael Ledeen, who have been harping on Iran for decades. Bush is weak, and very highly susceptible to manipulation.

He's going to do it unless Congress stops him.
