My guess would be that, sometimes, it's best not to show the other side what you're really capable of.
As long as they're launching nothing more threatening than overgrown bottle rockets, I'd stick to the political outrage angle, and elect not to demonstrate exactly what I can do, and how I do it...let 'em sweat.
What really concerns me is that we've spent $92 billion on missile defense. I sure hope the blasted thing actually works...
