It has become very clear over the last couple of years that Putin doesn't want nuclear war either. Lots of nuclear threats, all of them backtracked. If we marched on Moscow the way we marched on Berlin that might change his mind. But If we push Russia back to Ukraine's rightful border and build a line of fortifications there, Russia has no point where launching nukes is actually advantageous to them. If anything, nukes only remain an option because of the lack of Western troops in Ukraine, allowing Putin to make a limited nuclear attack that hits Ukrainians but isn't worth war a nuclear war for the West. And even that is a trigger Putin has repeatedly refused to pull, preferring to win the war the conventional way even if that takes years
