Ouch. I agree with Sowell. We shouldn't be setting ourselves up as the defender of other country on the planet, especially when we don't have the will to go through with it. What Russia is doing to Georgia sucks, but they've effectively called our bluff.
NATO is our military's welfare handout to Europe, and is probably a large part of the reason they're fat, lazy and dying. Give the former Warsaw Pact countries a generation to forget, and they'll be spoiled too. We'd all be better off if they moved out and started taking care of themselves.
