Wasn't the threat of terrorism the reason for going to war against Iraq and Afghanistan? Isn't that why your president calls it a War on Terrorism? Heh. GG. The threat of nuclear destruction didn't stop the backward nations of Iraq and Afghanistan from becoming a threat to US national security. Nuclear weapons and M.A.D. don't work against rogue states or rogue individuals. You very much do have to "worry about countries". Sigh back in the day some one mentioned the US and Nukes in the same sentence and respect was in the next subject, but now every one knows it would take alot more then blowing up millions for the US to use nuclear weapons THAT is why terrorists attack with out fear and leaders rally against the US, but if u did push the US to far there would be -*BAD WORD*- to pay and i sure wouldint wanna be anywhare near that storm. think about past events people have tried full out war on the US it didint work infact most full attacks on the US do more harm to the attacker then the attacked Pearl Harbor is a perfect example of pushing the US to far and look what happined as a result o f that?
