It's to my belief that whoever uses a nuke first loses all their allies. Besides, China has too much in stake in the US economy to side with Russia, there goes one of the motherlands main backers, financially speaking.

Russia need not use the nuke, only threaten it, as they are now.

Russia would be annihilated, but say, 30 million of us would go. Russia would be risking nothing. We won't nuke them just for threatening us, so if by some miracle we found the nerve to stand up to Putin, he would back down.
