I suppose it's the first time he's pointed a finger at GWB and I hope he has the guts to repeat that tonight as well as his claim that he never called the President a liar.
As usual, there is a grain of truth in what the Kerry camp is saying. Shinseki ran afoul of Rumsfeld very early in the Admin. That was even before 9/11. As a result, he set his retirement date early. But that date didn't come until after the Iraq War started.
So, yes, Shinseki was forced out by the Admin. But, no, it had nothing to do with Iraq. Shinseki's comments on Iraq were probably just sour grapes.
