These are the hawks, always eager to have a little bit more war. The problem with their eagerness is that going to war in, say, Pakistan (the newest possible target) while also staying in Iraq requires some sort of cloning of the military and the Bush administration is dead-set against cloning. Or it requires hiring mercenaries and we know how well that works.
In short, the U.S. does indeed have the largest stock of WMDs and nuclear bombs and the like, and the largest military budget of any country on earth (in fact, several times larger than the next largest such budget), but the U.S. does not have millions and millions of spare soldiers. Any attempt to extend some sort of warfare to several countries would fail unless it was carried out by distance bombing only. I wish the little drummer boys would make it clear that they are talking about turning countries into glass-covered parking lots, because that's what the only realistic strategy to winning such wars would entail.
