The outcome is not clear at all unless you can assure us what Russia will do with the weapons they have.
Unless Russia wants to commit national suicide they’ll keep their nukes secured.
For some reason the Putinists are advancing a narrative that Russia can use nukes against NATO unopposed. That’s not how that works.
And what’s the point of nuking Ukraine? Spite? That may very well trigger a first strike against Russia by NATO. No, I don’t think Russia is crazy or stupid enough to do either.
