I'm not afraid of dying by any WMD. I think it would be highly unlikely that I would because I think only major cities would be attacked, leaving the rest of the country alive. If that were to ever happen, the lucky ones would be the dead ones. The unlucky ones would be the ones still left living as they would have to deal with the horror of millions dying, the economy going completely belly up, and probably BO waving a white flag of surrender to whoever attacked us. Plus a million other problems...
If we have the right leadership, we could survive being attacked. Look at Japan, they made it through and managed to eventually thrive again. Even after devastation, a lot depends on the leadership and how well they want to do their jobs as to how long it takes a nation to get back on its feet again. I have zero confidence in our current administration.
