We could take care of that easily with the one weapon we should, but won't use. If we had used one after 9/11, none of our troops would be in harms way over there now.
Let the rest of the world scream and holler. I'd rather they fear us than like us.
Since they don't like us now - I would just as soon scare the 'ell out of 'em. Let them keep their pantaloons in a wad wondering what we are going to do next to offend them. :o)
