The EU proposal actually talks about this. ICC has no jurisdiction over Crime of Agression. Actual starting of the war. Since by accident/intentionally nobody gave ICC that jurisdiction/ Russia is hardly going to volunteer to agree to give it jurisdiction
ICC can handle the individual war crimes, crimes against humanity.





Whatever desperation Putin has before using Nukes it is nothing compared to how desperate his situation would be after. It is not west he needs to be concerned then. It is India and China. Both have made clear Nukes are not to be used.
Russian economy would collapse, if China and India cut ties. Not to mention China might just walk over the eastern border and come clean house with and in Russia for their insolence of not heeding Peking. It’s 140 million person country vs. 1 billion person country and PLA isn’t any more the “every third guy gets actual rifle” people’s resistance army.
He would put himself and most likely his family and children at risk. Since using nukes like that is the level of thing where ruthless country like China absolutely would come for the culprit and their family. Since “you might not care about your life anymore old man, but we are pretty sure you care about your children and grand children”.
Medieval (quite literally). “Yeah, we snatched your grand child as hostage.” You behave now and they might life.
