This is from Bob Woodward's new book about the decision to start the surge:
The (Joint) chiefs' frustration grew so intense that (Joint Chief Chairman) Pace told Bush, "You need to sit down with them, Mr. President, and hear from them directly."
(National Security Advisor Steven)Hadley saw it as an opportunity. He arranged for Bush and Vice President Cheney to visit the JCS in the tank Dec. 13, 2006. The president would come armed with what Hadley called "sweeteners" -- more budget money and a promise to increase the size of the active-duty Army and Marine Corps. It would also be a symbolic visit, important to the chiefs because the president would be on their territory.
"Mr. President," Schoomaker began, "you know that five brigades is really 15."
Schoomaker was in charge of generating the force for the Army. Sending five new brigades to Iraq meant another five would have to take their place in line, and to sustain the surge, another five behind them. This could not be done, Schoomaker said, without either calling up the National Guard and Reserves or extending the 12-month tours in Iraq. The Army had hoped to go in the other direction and cut tours to nine months.
Would a surge transform the situation? Schoomaker asked. If not, why do it? "I don't think that you have the time to surge and generate enough forces for this thing to continue to go," he said.
"Pete, I'm the president," Bush said. "And I've got the time."
What I find interesting about all of this is that we were notified two days later that the 1-325 was going back as part of the surge. How does that happen?
