> Why do you think this? Unless we're going to start WWIII over this, all of the things currently preventing us from imposing harsher sanctions on Russia will remain as strong - most importantly, Europe still needs Russian gas to be able to sustain its industry and population comfort. MAD requires a overwhelming response to any nuclear use, it is true that Ukraine doesn’t have nukes so that response won’t be nuclear itself. But if the world just “lets it go” then it would be speed up nuclear proliferation like no tomorrow. I believe any use of a nuke is the end of Russia even if it’s a slow fall.
