I searched under the tags "rant" and "Afghanistan" for this rant and didn't find it under the former; as for the latter, I haven't used that tag until now. (ETA: I also searched under the "Daily Kos" tag--no luck there, either.) Since I apparently haven't posted it before (and I'm surprised that I haven't), here it is.
I used to play a game called Pax Brittanica, which simulated world conditions from 1880-1916. In that game, Afghanistan was a region that was 1) most likely to revolt, 2) a real pain to conquer, and 3) cost more to govern than could ever be extracted from it. Furthermore, should anyone ever be dumb enough to actually invade it, the mere act of occupying the country would be enough to give at least one major power, if not two, cause to declare war. In the games I played, no one ever messed with the place.
If a friggin' game can figure that out, why can't people do so in the real world? Yeah, I know, Osama bin Ladin and the Taliban. Still, the above wisdom should have been enough to convince people to get in, get the job done, and get out.
I still stand by this piece of wisdom I gained by being a gamer geek.
Speaking of Pax Brittanica, I have a story about the last time I played that game that I've never written down. Even though it's not a "NOW" story, it's time to blog about it.
