Cold War saber rattling at its best. Nothing less, nothing more. I'm not worried, or unsettled, at this point.
You should be, we are expanding our nuclear weapons in central Europe after signing non-proliferation treaties, we taking part in barbaric torture, and withholding primary civil rights, we are spying on our own population and citizens, we are labeling countries as part of an axis of evil, we are threatening and manuevering with swagger. You should be very unsettled.
Napoleon and Hitler underestimated the Bear. I kind of think Bush and Cheney are just wadding up balls hoping someone else will throw them. Just like Georgia did with South Ossetia.
