If Bin Laden pulled off something like multiple nuclear bombs going off it would be the end of the USA as we know it. In that case I would hope that enough of the country remains intact long enough to completely and totally eradicate our enemies off the face of the earth.
I think it depends on what you mean by "as we know it." I think the human spirit in general and the American spirit in particular is incredibly resilient. I do not believe even several nuked cities will cause the country to be destroyed.
The principles upon which the nation was founded - although atrophied by modern society - still exist, and are cherished by many. And they don't depend on gleaming cities to exist or flourish.
I hope my opinion is never tested, since I live in LA and would have to watch the drama play out on a celestial television. :-)
Would you STOP that whiny, defeatist bullshit?? What's with you "omg.......a few nukes and the US as we know it is FINISHED!!!" crowd??
We have become such a nation of pussies. You obviously didn't paricipate in the Cold War.
