I would agree with that given the current leaders in place. They are self-preserving by avoiding a major war.I tend to think this is less and less likely on a major scale. The major powers are far too economically intertwined for the powers that be that ultimately drive wars to benefit from any direct conflict between the major powers
Now, it would be naive to believe that couldn't change very quickly with the wrong leader in any one of Russia, China, North Korea, or the US. But even if one were to do something rash, the collective of others may be more restrained than in other warry times.
I don't think China and the US are going to all-out war over Taiwan, but who knows, all the professionals think it's inevitable.
Russia could make the horrible decision to use a tactical nuke in Ukraine, though I think Putin knows that's not a viable end-game for him. He may be a narcissistic dictator, but he's not stupid. And if he did, I'm guessing the reaction would be limited to targeted missile strikes into Russia in strategic ways to avoid further escalation.
