No, I have no reason to think that Russia wants to commit suicide by attacking NATO with nuclear weapons if they meet resistance while trying to invade a NATO country, nor that they want to watch their military get wiped out in a conventional attack against NATO (leaving them defenseless against China and internal elements.
This isn’t 1989, and Russia doesn’t have anywhere near the muscle that they used to have, in fact much of that muscle switched over to NATO, they don’t have the military to imagine that they can conquer Western Europe and defeat America and the rest of NATO in war, so there is no MAD situation existing today, or one where we have to depend on the last ditch defense of tactical nukes to halt the massive millions of the Soviet hordes sweeping into the capitols of the West.
In your imagination, you have Russia wanting to go nuclear against everyone to make up for their lack of military, in the case of NATO to conduct invasions of NATO nations, and in the case of China, to defend against losing some of their territory.
“Including general nuclear warfare with an equivalent nuclear power.” and France and Britain.
Russia has no interest in Ukraine that is worth that promise. None.
The scenario under discussion, and the very point of the article you are posting under, is the expansion of NATO to include Ukraine, while Ukraine is under Russian occupation.
Why do you keep imagining other, not relevant scenarios not posited by anyone but you?
You are building straw men, tearing them down, then impugning the character of anyone who does not support your rhetorical efforts.
Are you the only one who does not see that?
