Both wars are wrong, and there is a lot of shit going on in the Afghans that they simply don't report. My neiece said gun fire was everyday and said every week a helicopter was being shot down or a supply truck or whatever being blown up. As for "immediate" withdrawl I don't know man. I believe a gradual pull out might be best in this case, but fuck that. I would actually call a cease fire and try to meet with the enemy. Thats what I would do.
But to answer the questions I say a pull out in both countries, but I don't see a difference between the two wars (except for one gets more coverage.)
