So, a nuclear war would be the consequence of NATO nuking Russia as a consequence of Russia nuking Ukraine.
How do you read NATO "neutralizing" all nuclear threats, other than a direct attack on Russian nuclear assets? A direct attack on Russian nuclear assets will start WWIII.
Unless NATO can neutralize every single Russian nuclear sub all over the world all at once, then how can we prevent Russia from firing nuclear weapons at our cities, or at least our military assets?
Russia has more advanced hyper-sonic missiles than NATO, and they have already used them with conventional warheads in Ukraine. We don't even have the capacity to effectively track Russian hyper-sonic missiles. Russia has a clear advantage with nuclear first strikes. And it is profoundly stupid and irresponsible for NATO to risk those consequences.
