Most people don't understand the value of Nuclear Weapon is the threat of using them, not actually using it. Because something we have is called Threat Matrix.
Once nuclear weapon was used, actually used by any side, there are no longer in doubt that they WILL BE USED, which mean the defence mechanism is that we need to treat the usage of nuclear weapon is likely, instead of unlikely, which means the first thing we do is to hunt down remaining Russian nuclear weapon and neutralise it, because we can't say "Oh, they may not use them" when the Russian already did, so we will have to assume they are going to use them, which mean the defensive posture will change from passive to active, hence hunting the remaining nuclear weapon down.
This is what we called "Full Count" when I was in the military, basically account for all mobile nuclear weapon and strike them before it was used, and target all command post that will stop the launch with Sub hunt, AIrbase hunt and CP hunt, anything that's not launching a nuclear strike on our own, but instead using conventional force to hunt down Russian nuclear capability, the effect is that it will minimise damage if Russia decided to launch their remaining nuclear weapon.
We won't just be sitting down and waiting and see whether or not Russia will use them again, you presume they WILL BE used again, and that would mean rather than de-escalation, it will be minimisation. De-escalation is what we will do now, to "Prevent" Russia from launching those nukes, but once that nuke was launch, that's ship would have sailed.
