Israel probably doesn’t need a tribunal. Not because they didn’t commit war crimes or anything like that, but because this tribunal exists for one very specific reason.

When you read “Nuremberg-style tribunal” you probably thought “crimes so bad they had to create a new court for them” but that’s not really the case. Because after the Nuremberg trials the international community set up the international courts in The Hague to deal with crimes against humanity. Unfortunately they made a mistake. They forgot to include one crime in the jurisdiction of the courts. So, to prosecute this specific crime they need an additional court, while all other crimes will be judged by the existing ICC and ICJ.

The crime in question is “aggression”, basically the “crime of starting a war without provocation”. And that’s a lot easier to prove for Russia than for Israel, where the conflict includes other parties that also acted militarily.
