I like how you are certain enough about the state of Russia's nuclear armament to bet the lives of everyone on the continent on it. People said the same things about all of the tanks Russia had in storage, but they're bringing them online and putting them in action in the Ukrainian theater just fine.

Even if 90% of the nuclear arsenal is inoperative, more than enough remains to reduce the world to cinders. Even if we assume high levels of corruption throughout the Russian army, a 90% failure rate would be outrageously high. Sure, Russia is never as strong as they claim to be. Their capacity is almost certainly exaggerated. But the idea that not a single of Russia's nuclear weapons would successfully detonate on target is hopium to the highest degree.
