I have always boggled at the fact that anyone could see any merits in the proposed US ballistic missile defence system. The more I looked into it, the more convinced I became that it was a technology that would never work against a threat that did not exist. So I was glad to see that President Obama has cancelled the proposed deployment of the missile defence system to Eastern Europe. This isn't about giving in to Russia or Iran; it's about not throwing good money after bad. Excellent analysis here.
