Joe Klein previews Obama's Afghanistan speech:
This will be portrayed as the return of the 30,000 “surge” troops deployed last year, but that’s not quite accurate. The troops being withdrawn, especially those coming home this year, will be mostly support personnel, the engineers and construction workers who built the facilities to house the amped up US presence in Afghanistan. The military commanders want to keep as many combat units as possible–i.e. nearly all of them–for this year’s fighting season.
