I think it's time for UK, France, Poland and Germany to get into the war in Ukraine and push Russia back to their border and set up nuclear weapons in Ukraine under their control.
Europe would have gained some of the most experienced army in an alliance and cross-train like crazy. They would have some capacity to hold their own against Russia in absence of US Military.
If Russia want a nuclear war, then so be it. There's nothing to discuss there, it just means they were planning on using it from the start. Better to die on your feet than on your knees.
Buddy, that's just WWIII. And the problem, with that is, the people that are losing just might go ''well... might as well....'' and irradiate the planet to sterile.
