Do you really think an extra 10,000 troops would have made a significant difference?
I don’t know, I am not a General, so that is not my area of expertise. The one who was there said it would have. Can I assume by your skepticism you have more information than Petraeus did? Sounds like you think it wouldn’t have helped, which means you agree with Obastard that shorting the general’s request was the right thing to do.
