Trump, to borrow a phrase (cannot recall where I might have heard it), must be tired of all the winning he has been doing. It is the only explanation I can think of for the decision he and his handlers have made to double down in Afghanistan. Well, now he will get a great big lose-burger to eat. Sadly, it will be costly for all of us.
History is ready to teach us if we are ready to learn.
The relevant lesson to learn is that outsiders never win in Afghanistan. You can pour in all the national blood and treasure that you want, in the end you leave with nothing. Whether or not you are attempting nation building has nothing to do with it. The nature of the place itself, and that of its people, dictate that outsiders lose. Poppy crops and civil wars can come and go, but the heart of the country never changes and cannot be defeated by anyone foolish enough to wander in there with conquest on their mind.
So now the US is going to waste more money and destroy more lives by perpetuating the longest war we’ve ever prosecuted. Sad!
