I don't see anyone risking a global nuclear exchange by intervening in Ukraine if the Russians use nukes. I also think the average person probably underestimates how personal this is for the Russians. It's akin to the US fighting a war in Canada over resources, and what they believe to be an unacceptable military encroachment by an old enemy. This is probably the closest we've been to nuclear weapons being used since the Cuban missile crisis, maybe even since the second world war.
