No one is going to launch a nuke in defense of Ukraine. Russia might launch a nuke as an offensive tactic. If they did that, it's the end of Russia, and depending on the escalation, the end of the world as we know it. No one can control what will happen, but the simple reality is that allowing Russia to push a war of aggression out of fear of a nuclear attack endorses the idea that anyone with Nuclear capability can do what they want. China, India, etc can annex or invade and no one will stop them because it might trigger escalation. That reinforces the need for less powerful nations to pursue nuclear capability. Those smaller, less stable nations will be more likely to lose control of a nuclear weapon. It's a catch 22 so we might as well try to err on the side of stopping wars of aggression. The other path is open for the cowards who would rather bend the knee or look the other way until aggression knocks on their front door.
