As a world, several decades ago, we reached the position where the weapons systems we have developed can easily destroy all human civilization and wipe out all but a small fraction of the human race… and possibly all of it. The planet will endure and possibly even recover, over eons, from such destruction, but at a terrible cost.
For the last few decades, the world powers have managed not to unleash such destruction, but now we’re closer to that possibility than ever before. So what has changed?
The idea that mutual assured destruction would avert nuclear calamity rests on a fundamental assumption – that no political leader wants to destroy the world, because such destruction would result in self-annihilation. There’s a sub-assumption behind that premise, which is that political leaders will act rationally, but what’s rational to most people isn’t necessarily rational to those with extremist beliefs.
“Give me liberty or give me death” is a powerful statement, but what about Vladimir Putin’s attitude of, “If you interfere with my attack on Ukraine, I will loose nuclear fury,” and possibly destroy civilization?
Yet the Ukrainians are fighting for freedom, for their liberty, and most likely tens of thousands have already died, just to remain free of Russian control. But if the United States enters that conflict militarily, Putin might well use nuclear weapons. If the U.S. provides defensive weapons that allow Ukraine to force the Russians from Ukraine, or even force a stalemate, might not Putin issue the same threat?
Putin is capable of using tactical nuclear devices. The question is whether he is willing to use them. If he does, then what? If the U.S. replies in kind, so will Putin. And if Europe and the U.S. back down, what happens if he goes after Poland or Finland next?
Once again, the world is faced with a leader who wants to force oppression on others, leading a people unwilling to remove him…but Hitler didn’t have nuclear weapons.
