What proof… you don’t have any proof either… except for the statements by a regime that has been outright lying and bluffing this entire war. And was called on their bluf so many times we lost count.
There is no telling what a power mad dictator will do when threatened. And I agree their calculation on the use of nuclear weapons MIGHT change. But the counterweight to that is that many many more countries will isolate them and the question will be if this moves the needle in any discernible way towards actual use.
And countering my calling out your concern trolling with “no, you are” does not take away that you are here amplifying Kremlin talking points and trying to Stoke fear on the use of nuclear weapons (without actually saying nuclear) by the evil Z idiots.
Edit: jeez it seems the trolls of Lemmygrad are leaking again.
