Not worried about it. Until they grab our guns, we will always win...and they know this too. We are the only major country in the world that has more guns than people. It isn't even close. The largest military in the world, China, has around 2 million soldiers. Even if you added up the next four major powers, you would have less than 10 million active military personnel combined. We have over 340 million people, with more than one gun per citizen. Even if we sucked, we would still defeat them because we would outnumber them 34 to 1. So let them attempt to implement a carbon footprint tracker system that begins to seriously affect our way of life and let's see how things end up.
