I thought cute and run meant that we are to scared to finish what we started, that the enemy is too powerful for us to manage. What I see in Iraq is not an enemy we can not handle, it's a population we believed could do better without Saddam but instead would rather let them be what they are today so they can solve their own problems. To believe that we should just let them take over from here on and let them be is not cut and run. We did what we could and they do not wish our help anymore, we should not force them to except our help.
Maybe a civil war is possible, maybe a civil war is necessary. We may not think that death is the best way to solve problems but who are we to tell them that. If they want a better life and are willing to die for it, in a civil war like the one fought in the US once upon a time, then so be it. I therefore see it unnecessary for us to be there any longer, but in the case that we created yet another enemy then we should leave them with the warning that next time around we won't hold back and do our best to show them we are serious.
Murtha's idea was for us to admit that we couldn't handle it and we should just leave them to their own demise. Kinda like when you are helping someone and when the going gets tough you leave them on their own cause it was too much for you. Kinda cowardly and immoral to leave a half job.
