Commander Said to Be Open to More Troops

For the first time, General Casey is saying that he's open to more troops.

"Until recently, the top ground commander in Iraq, Gen. George W. Casey Jr., has argued that sending more American forces into Baghdad and Anbar Province, the two most violent regions of Iraq, would increase the Iraqi dependency on Washington, and in the words of one senior official, “make this feel more like an occupation.”

Well, according to the NY Times, this has changed. My question is, why does a guy like this change his mind? Where's the pressure coming from? Or is this just a coincidental change-of-heart? Looks like to me like someone is trying to get all their ducks in a row. Cheney, anyone?
