Is General Petraeus Just Walking Lock Step with the Bush Administration?

A good bit of skepticism is healthy in life, but especially healthy when it comes to politics and politicians. As much as we'd all like to believe General Petraeus, it's hard to believe that given this administrations history of cronyism and back-slapping "heckuva job, Brown-ies" that Petraeus isn't simply walking lock step with the Bush Administration on this. There's a LOT of money to be made by prolonging this war and it's sad to say, but I think that's one of the major factors contributing to it's continuation. Any thoughts?
