Russia doesn’t recognise the court

They aren’t a member and so won’t show up. So you would have to try them in absence and then even if someone is found guilty what next? Same issue as above. You’ve already done the punishment (Sanctions).
Anything else would just be Political Posturing (Same as the warrant for Putin)
Upsetting russia was seen as bad plan when trying to normalise relations with them and the rest of Europe (Pre Crimea) The idea was to intertwine economies so that was would never be feasible.
World is dependent on China for manufacturing
When the punishment for countries is economic (As no one would dare go to war with a Nuclear power) and you depend on their economy you don’t need have much to gain do you? Just ruins everything. You could go for specific people I guess but their countries will just ignore it.
Israel is/pretends to be normal with most of the world. So will probably actually do stuff if they lose.
Then the obvious. It’s all political theatre and no one actually cares about genocide.
I think most countries that support Ukrainian have already said as much. China and Russia will vote down anything in the UN as two permanent members of the security council.
Because after surviving the Holocaust the state of Israel was formed by expulsion of natives, colonialism, war and, possibly, genocide.

I would recommend starting with the history of Israel from the First World War and going chronologically. It is a messy conflict with stupid numbers of massacres and atrocities by the PLO, Israeli government and both of their predecessors.
Long story short though. Israel and the PLO have, with certainty, committed various “war crimes” in the past. As Israel won the war(s) the loser of those wars can very easily claim Genocide. If it was the other way around with the PLO winning the wars then we would see the reverse right now.
Accusing someone/a country of a crime does not mean they did it. Being a victim in the past (Holocaust) does not mean that they are immune to criticism/criminal proceeding for future actions.
