Tripping on the escalator

17,000 US troops to Afghanistan then, another 40,000 now... pretty soon this adds up to maybe, uh, 550,000, troops. A real holy hell of a Viet-Nam scale escalation! Well, we've done it before, so we do it again! You know the classic therapeutic definition of insanity, "doing the same thing the same way and expecting a different result!" It's now obvious that US policy makers and shakers are forking insane!
