Is withdrawal from the war in Iraq a Catch-22 tragedy where it's immoral to stay & even more immoral to leave?

The answers you've gotten are great, so I won't write too much except to say that it's refreshing to see a young person who is so informed and intelligent about the world. Thank you for not being an apathetic youth who doesn't know or care about what's going on over there. I do agree that it's the worst mistake ever made, and I think it's like Vietnam 2. One day you are going to a leader in this world and I think you are going to change it for the better. You're a young genius, but more importantly you are compionate, diplomatic, and you care. I'm looking forward to the day when you are in charge.
