Yes, the US military should leave Iraq and Afghanistan. But it should leave not because it is impossible for a modern military to defeat a bunch of tribal warriors. It should leave because it is fighting an American civil war by proxy. One, this is just sick. And two, the right place to fight a civil war is always at home.
