Nonsense. If there is a nuclear war it will be started by Russia. And I don’t think Russia is insane enough to do that.==
You are wrong. Russia will use tactical nukes on battlefield if needed to reach a victory. Of cause she will NOT launch strategic missiles toward NATO capitals at first place but will answer immediately if she sees such launch toward her. It is in her military doctrine. Read it.
“Russia reserves the right to use nuclear weapons in response to the use of nuclear and other types of weapons of mass destruction against it or its allies, and also in case of aggression against Russia with the use of conventional weapons when the very existence of the state is threatened.”[13] https://en.wikipedia.org/wiki/Military_doctrine_of_Russia
“You are wrong. Russia will use tactical nukes on battlefield if needed to reach a victory.”
I don’t think so. It would lose what little foreign support it currently has. Besides, it would be an admission that its conventional forces are so poor it can’t defeat a smaller and weaker neighbor WITHOUT having to resort to nukes.
“Of cause she will NOT launch strategic missiles toward NATO capitals at first place but will answer immediately if she sees such launch toward her. It is in her military doctrine. Read it.”
I have. It is similar to ours.
Your cite for use of nukes against a conventional foe states that nukes will only be considered for use “when the very existence of the state is threatened.” Are you seriously saying that Ukraine poses an existential threat to Russia? Are you saying that Russia is so weak, and so pathetic, and so backward that Ukraine poses an existential threat?
