No one "wins" a nuclear war. We all have to eat and breathe radioactive fallout for years!
Shifting topics, Ukraine has shown that the mighty Soviet Army of yesteryear is a fraction of what it was. Little bitty Ukraine has used our superior arms to hold them at bay. And no one wins there, either. Death and destruction over a madman's whims. Tom Clancy had the right idea when he created the fictional "Ryan Doctrine". One missile hitting Putin's residence while he is sleeping there would stop all the insanity quite quickly.
