I don't think we'd launch nukes over one step. I think Russia could even get away with "peace keeping" a "Russian separatist group" in a Nato country like Latvia. Which is what makes this war so strange. Russia could've easily stolen Donbas - and NO ONE in the world would've cared. They could've taken away one state at a time, and NO ONE would have cared. There was no reason to rush. But if Russia nuked a NATO population center, or even just invaded to this degree a NATO country - that's MAD.
