I guess my point is that if someone wanted to deliver a weapon of mass destructon, and we had a missile defence shield, they could very easily find another way to deliver their weapon. So the shield would not serve to deter, or to protect. It would only make aggressors look for other alternatives. We saw a very compelling example of this on Tuesday.

We need to put our resourses into things that work. Not things that only serve to make us feel more secure.
