Enough ordnance lying around for them and their army and menfolk to have fought if they wanted to. At some point we have to say enough is enough. Thousands of American lives, trillions of American dollars, and 20 years ought to have been enough. If not, then it's just not a job that is reasonably accomplishable by a foreign state. I wish them all the best in building a free society for themselves over the next decades, but they'll have to do it without American boots on the ground.

Maybe its China's turn to try to conquer the graveyard of empires.
