I understand that Nazi and Allies was in war because of racism and soul of occupation runing in both of them .Nuclear weapons were invented by a huge group of people, many with idealistic motives, and many out of fear the Nazis would get them first. Not to mention other, perhaps lesser, motives.
how about NOW , why Russia and USA and many others countries holding and develope these weapons ?
which mean if a war start , so thats mean it's THE END !
