Will the u.s. still be around for it? Somehow, I doubt it. I don't think it'll be around in 3 years if it keeps going as it is. I also wouldn't be surprised if all of a sudden veterans start keeling over from 'unknown causes' after their usefulness is over on the combat field.
Hey. It's cheaper than military benefits. Of course this is speculation, but who knows?!
