Missile Defense System

[Ice]

I think the development of this is good because if a country like North Korea ever launched a primative nuke at us, we would able to shot it down. I understad it's useless against someone like Russia because of the newer technology and the sheer number they can fire.

EDIT:

Here is a site with information on the Missile Defense System:
