Threatening with conventional arms is not the same as threatening to use nuclear arms. Many countries threaten to use their military - yet Russia is going as far to threaten the offensive use of nukes. I’m discussing the reality of now not some theoretical future/parallel universe as what’s the point? Russia is doing what Russia is now and that’s the problem.
Are you old enough to be sure you will be dead in 20 years? If not, then making sure we won't be all dying in a "fire and fury" would be the point. Otherwise, I guess, you have the luxury of not thinking about "future/parallel universe" that might just one day become the reality.
