Not only that, Derm...our soldiers and equipment are elsewhere; they can't protect us. We could be invaded by practically anyone, and it'd take weeks to mount an effective response. And the cost? Now that we've sold the military to private contractors on the presumption that they're less expensive, and found out what prevarication THAT was, we're even more screwed economically.

We'd have a hard time drumming up allies in the event of an attack or an invasion, also; the rest of the world is fortunately wiser than to send their soldiers to die for someone else's hubris.
