> SDI made sense. We still have SDI. Now we call its "Strategic Missile Defense" and its our biggest counter against rogue nation nuke launches and other attacks. It also has Putin scared as he can't match it and is demanding we don't continue to build new sites in Eastern Europe out of desperation.

You just basically said that SDI is destabilizing because it will take away MAD. I fail to see how supporting that is rational or sane.
