I wasn't in favor in any sense of spending the money to build an anti-missile defense shield..it's a stupid use of money from many standpoints. If I was a nuclear power, I'd just get some submarines close enough to the coasts and launch nuclear armed cruise missiles. Unstoppable.

Moving right along, if you think that a multi-billion dollar 'umbrella' is a good idea, read The protection paradox over at the Bulletin of the Atomic Scientists. Always great stuff over there.

It's real geek stuff, so it won't be for everyone. But it illuminates what the U.S. has done in the past to overcome Soviet missile defenses. Brand new stuff as far as I know.
