Have you really shifted the responsibility to prove YOUR point to me? LOL, you just raised a major "I am arguing in bad faith" flag. Point me to a specific precedent when Russia followed up on its nuclear threats for the Russian-occupied territory of the country with internationally recognized borders. If you won't I will consider that you had no actual idea what you were talking about when you wrote:

>Historically, you’re also wrong.

That has nothing to do with the consequences of the NATO military intervention though. It's unknown if Russia will actually escalate if NATO intervenes, you just choose to believe that they will double down citing "omg I spent an hour reading about military doctrines, trust me bro" while I choose to believe that they will retreat because it just isn't rational to start a conventional or nuclear war against NATO. Perhaps it will be some combination of both so Putin can "save face", but all-out nuclear war or WW3? Definitely nope.
