I would not volunteer as things stand today. Afghanistan was a legitimate target but we still haven't finished the job over there. Two and one half years now and OBL is still hiding out with Mullah Omar and company. Iraq was a costly mistake.
No, if the President asked for volunteers today I would not step forward.
Sleeper troll alert...
Good. There are other ways to serve your country. We still don't have enough backseat drivers and armchair generals. Somebody's gotta do it!
