This really is a tough subject but I had to vote that it is time to go. That worry for a failed state falling back into the wrong hands of course comes to mind but at the same time we are spending quite a bit (in lives and dollars) on a conflict with questionable results the further we go. I am starting to think we would be better off dealing with all the various factions of people in Afghanistan (who can't seem to agree anyway on a true national level active controlling government) through intelligence operations over active military occupation. I am just no sure the long term goals will be achieved in Afghanistan now that we know what is going on, and who is living reasonably well, across the ridge in Pakistan. Just seems to be far more going on over there against us than for us. Again, tough subject I am not 100% sure on.
