The US is deploying a $1B missile defense system, primarily to Alaska, which has at best a 50% success record (bad news if you’re missile with a huge radar generator attached heading from a known direction at a known time), to shoot down missiles from North Korea, which can’t reach the US and can’t possibly have missile-launchable nukes attached.
Those Star Wars Buck Turgidsons must have gotten an erection when KJU started rattling his empty saber again. The missiles won’t even be deployed til 2017, so even if they were effective, they wouldn’t be useful for this “crisis”.
But the missiles are very useful for deploying $1B of funds which might have otherwise been sequestered.
