Both the Secretary of Defense and the President have said repeatedly that if the commanders want more troops all they have to do is ask for them, That does not sound like they are being pressured not to ask for them. The commanders have also repeatedly testified before the congress that they did not need more troops. I get the impression that they felt like the smaller foot print to maintain the situation until the Iraqis could take over was their plan all along. They all have been recommending Laurences Seven Pillars which says you need to get the Arabs involved. At this point I do not see any reason not to take the commanders at their word.
