Gen. McChrystal: U.S. Needs More Troops in Afghanistan or We'll Lose

The report by General McChrystal is included in a pdf file. Where are we going to get the troops? The public is turning against the war, along with other Democrats. Our forces in Afghanistan are basically propping up a corrupt central government that has little power through much of the country. The warlords, along with the Taliban, are becoming rich from Heroin trafficking. Time to get out.

Gen. Stanley McChrystal, the top U.S. and NATO commander in Afghanistan, said in a confidential report that without additional forces, the war against insurgents there will end in failure, The Washington Post reported Monday.

McChrystal's grim assessment of the war was published on the Post's Web site, with some portions withheld at the government's request.

"Although considerable effort and sacrifice have resulted in some progress, many indicators suggest the overall effort is deteriorating," McChrystal wrote in his summary.
