Well, isn't this interesting (as the Church Lady might have said):

“We can put in 20,000 more Americans tomorrow and achieve a temporary effect,&rdquo he said. “But when you look at the overall American force pool that's available out there, the ability to sustain that commitment is simply not something that we have right now with the size of the Army and the Marine Corps.”

General Abizaid also publicly said for the first time that the American position in Iraq had been undermined by the Bush administration's decision not to deploy a larger force to stabilize the country in 2003. That decision was made after Gen. Eric K. Shinseki, the Army chief of staff at the time, told Congress that several hundred thousand troops would be needed. His testimony was derided by Defense Secretary Donald H. Rumsfeld, and the general was ostracized at the Pentagon before his retirement a few months later.

“General Shinseki was right that a greater international force contribution, U.S. force contribution and Iraqi force contribution should have been available immediately after major combat operations,” General Abizaid said. “I think you can look back and say that more American troops would have been advisable in the early stages of May, June, July.”

Too bad no one listened to him outside of Left Blogtopia (and you know what a bunch of loons we are) and some of the "realists" left in the government, but who had no ability to influence the decision making one way or the other.
