High Noon: Another Maimed Soldier

I’m getting increasingly bothered by the human cost of the war in the Middle East that seems to go without end amend. In the last couple of weeks, two Montana soldiers have been maimed by IEDs in Afghanistan. The latest, 21-year-old Lance Cpl. Thomas Parker, was critically injured over the weekend. He lost both legs, his left hand, and suffered shrapnel woulds to his arm and eye. Originally, I was for the wars in the Middle East when the Bush administration insisted adamantly that there were weapons of mass destruction in Iraq. I also supported the war in Afghanistan as a response to the 9/11 attack. But now I wonder when is enough enough?

Question: How long should we keep sending our troops to Iraq & Afghanistan?
