Here is a serious suggestion.
Since it seems we are determined to keep doing what has proven to not work,how about we shake things up a little,and go "All WW-2" on their asses,and send in infantry and armor divisions,supported by pretty much everything in the US arsenal,and keep killing until there is nothing left to kill that is capable of making war?
Either that,or just get the hell OUT of that place?
Either way,what we have been doing the last few decades sure as hell isn't working,so WHY are we still doing it?
