Keeping me alive from who? The terrorists living in the caves of Afghanistan? Nah, you're right.. It's really scary bordering countries like Canada and Mexico.Spoken like a truly stupid person.
You do realize that our ability to rattle our saber the loudest is the only thing that is keeping you alive, right?

If you can look at that chart and tell me it's not bullshit then you're retarded. There's no reason to spend the amount we do on defense. We spend all this money to protect us from small groups of people living in caves, half way across the world. The only things we should spend serious money on are nuclear arms and at the same time work towards nuclear disarmament agreements with the countries that will cooperate. The real threat is China and Russia, and I highly doubt they'll attempt to invade the US, huge standing army or not.
