NATO, not counting the U.S.A. who is staying out of this scenario, has about 500 nuclear weapons to Russia's approximately 6,000. Let's say Russia launched half of their nuclear weapons in order to leave enough in reserve for other threats. Obviously, in an anything goes war, Russia's nuclear weapons would devastate the European Union. How much damage could the European Union do if they said screw it, let's do as much damage as we can and launched the nukes they have and launched as many conventional bombing attacks as they could before they went down? Would it be a more or less complete mutual destruction or would Russia survive?
