Well, that's the existing plan for the missile sheild. Strap a high powered laser under the wings of a plane and fly it around North Korea waiting for a rocket to appear. Once a rocket appears, shoot it down while it's still in booster phase. I don't know how Russia hopes to get around that difficulty. If we really succeed with the plan, they would have to have a new delivery system that didn't rely on boosters. Maybe they're going to have stealth nukes. <img src="/images/icons/smile.gif" />
