Invulnerable? Nah. But we see things a bit differently than the rest of the world. You see, the whole attitude that so annoys the rest of the world is the same attitude that guided the US to become what it is today. We are self-governed, self-reliant, and not afraid to take on the biggest challenges head-on.Through the use of innovation and hard work the US has went from a mud hole on the other side of the world to being the world's foremost superpower.Like a lot of Americans your gung ho attitudes make you think that you are invulnerable. Guess what, you aren't. A couple of nukes and you and the rest of the world are dust.
