Will Russia Use Nukes?

I would, i would not be surprised if russia does use nukes. They're already using the thermo barric bombs. These things are crazy. If putin had i think he would use it if nado intervenes. And then i'm worried about what happens to europe. Well, will we actually see russia say, you're knotkoing to nukus back? We can do what we want? I'm not entirely like it seems far fetched, but i also think it would be silly for us at this point. It would be optimism and normal cy bias to think a nuclear war would never happen.
