Ah, Johnny McCain

McCain has gone, in less than an hour, from saying that we must listen to the Generals to now it is okay to disagree with them, but one mustn't denigrate them. About

Half-an-hour ago:
These are the people we've entrusted to lead the greatest army in the world, we should listen to them. These are the people on the ground. They have the knowledge. Congress should listen to them.

Now: It is okay to disagree with the Generals, he did over the original war plan. Disagreement is fine. But one is not allowed to denigrate them by dismissing their statements because you've heard "from the Generals before."
