I always thought the whole Missile Defense Program was pie-in-the-sky doubletalk. I've been amazed how many otherwise rational people get angry when you say that and accuse you of wanting to have Koreans fire a missile into downtown Seattle or wherever. That it will probably never work is one of those silly technicalities that shouldn't stand in the way of us investing our time and resources in something that we want to believe will protect us from doomsday.
But now, says this article, even the people in charge of it don't believe it will ever work. Bet this doesn't make one bit of difference in how much we spend on it in the next few years.
