We've already been in it far too long at far too great a cost in money and lives. I have no problems leaving. Just don't pretend the war is over. It'll go on after we've left.
Then I guess it’s up to these countries to develop their own defenses...Just like we did. Of course since others like the U.S. tax payers have been footing the bill for many decades, these people don’t have a lot of incentive to get up off their asses and do something about it themselves.
