Ya know, the post was joking, I know ... but it ain't exactly wrong. Since we first got in this mess, who with real power in the US government (or British? I dunno bout that) has done anything about Afghanistan except tell people what they want to hear, but actually do the opposite, until now? Bush Jr. got us in there, but Obama didn't try to get us out. Neither did anyone involved in their administrations. Now you've got Trump actually acknowledging that it ain't good or ever gonna be good for the West (US, UK, Canada, etc) to be interjecting itself in Afghani affairs, and wanting to negotiate an orderly withdrawal. And even now there are 'establishment' people like John Bolton trying to stand in the way of it happening.
There must be an awful lot of money to be made from being on the reins-holding end of this war. And I suspect it has much to do with government defense contracts and heroin production/distribution.
