Ok? The ICC prosecutes war crimes in complementarity. The ICJ does not. Not sure what UN Security Council has to do with anything? I can't tell if this is AI. Add to your slop context you're probably thinking of IHL.

What you are leaving out is that governments can choose whether the ICC definition of warcrime applies to their territory. Iran has chosen that the Rome treaty, and the ICC, does not apply to Iran. It has even used this fact to request the ICC drop cases against them.

We all know why: 99.99% of warcrimes on Iranian territory were committed by Iran's islamist regime.

So Rome statute warcrimes are a legal impossibility in Iran. The Rome statute, that law and that definition of warcrime does not apply to anything happening in Iran.
