Because the missle defense system that Bouche is talking about is for ICBMs. The one he stuck in Alaska already is part of the Star Wars defense debacle.

Hell, if all you're worried about is scuds, we've got mucho ADA batterys for that. Or that thing the Navy's got, the Phalanx? or something like that? It's like a fricken brass factory when it fires.

But if we're only worried about short ranged stuff, then again, we should just protect our borders so they don't get close enough or inside to use them.
