seriously guys any country to ever use a nuke would not servive the consiquiences. and so by using a nuke you lose all word credibility, and susport, no leader would ever try to do this cause it would be like commitin suicide. right now the one real use of a nuke is symbolic. the only fear you could have of a nuclear attack is if it was conducted by a terrorist, in which case people in all of the major US cities should be worried and so would all the people in hte major cities of the major western countries.
