Whether Petreaus is actually competent or not is beside the point, he is an arse-licking politic hack and suck-up who only got the job because he was willing to kill more GIs than the next General.

Bush is as incompetent as they get. Failure at everything he's done, only became president because of Daddy's name, favors, connections, and Dubya is easily manipulated by his handlers like Cheney.

Bush wants diverse opinions like he wants to be held responsible for his actions. Not at all.
