well.. first of all.. we can't just pull out and leave. if we do then we leave iraq in particular in total anarchy. that's political suicide for any politician making that decision. let's be realistic. it's not gonna happen under any president at this point.
the problem with getting the lawlessness of iraq under control is the total lack of infrastructure in that country. cities are isolated from each other for the most part. personally i think the bush stance is right on point since the reconstruction plans include building/rebuilding said infrastructure. basically it's like the wild west of the 1800's in this country with automatic weapons.
honestly, i don't think there is a right or wrong way to go about dealing with the middle eastern countries. this is all uncharted territory. we've seen what non-involvement gets us under the clinton administration. now we go down the other road since the first was a dead end.
