This article from the Christian Science Monitor gives some clues. http://csmonitor.com/2004/1220/p01s01-uspo.html But I suppose the CS Monitor is another flacid libby propaganda organ now? Hold everything. Let me take my critical thinking cap off for a moment. Ann Scott Tyson has weighed in over at the CSMonitor. LOL!
The first 14 paragraphs of her article are recycled unsubstantiated charges from McCain and Hagel. 15 paragraphs into the article the author finally attempts to talk substantive specifics.
Start Excerpt:"This 'rolling start' was based on the continuing deployment of forces - seven to nine division equivalents over time - and we didn't think we'd have to fight for the ongoing deployments," says one senior Army officer, who spoke on condition of anonymity. "But we had to argue for days and weeks for further deployments that we thought were already approved," he said. "So while we were fighting the war, [we] spent untold hours rearranging the pieces of the deployment" and "justifying the need for brigades, battalions, and sometimes detachments," he said. "The [Secretary of Defense's] office wanted to personally approve every deployment." More generally, military officers are sharply critical of the failure of Pentagon leadership to anticipate the level of Iraqi opposition to the invasion. "Every major assumption they made about Iraq was wrong," said another senior Army officer. He said in a measure of the Pentagon's over-optimistic projections of how well the occupation would unfold, US troop levels by now were to have fallen to less than 25,000. Instead, US forces in Iraq are now increasing to 150,000._End Excerpt
Find me one named source from that excerpt. You can't. That's real cool isn't it? As I said before, you're not being objective.
Now I'll give you a named source and I give you what he said about who decided the level of troops for the invasion of Iraq.
The New York Times March 31, 2003 | Excerpt:"I think the toughest part is ahead of us as we start to engage the Republican Guard divisions that are arrayed around Baghdad," General Myers said on the NBC News Program "Meet the Press." "Nobody should have any illusions that this is going to be a quick and easy victory. This is going to be a tough war, a tough slog yet, and no responsible officials I know has ever said anything different once this war has started." The number of ground troops moved near Iraq before the war was decided over months of consultations among Gen. Tommy R. Franks, commander of the war, and the Joint Chiefs of Staff before Mr. Rumsfeld took it to the National Security Council and the president, he said. "It has been approved by everyone who's had a look at it," he said before one television appearance. "It's been described as an excellent plan. I'd be delighted to take credit for it, but it wouldn't be fair, because it's a product that is essentially General Franks's, but it certainly is the result of a lot of thought from a lot of very fine military planners." _End Excerpt
