The ICC really needs to hold authority over all countries. That’s where your quibbling should be taken.
Israel won’t join the ICC any time soon because reasons, and Gaza, well, Hamas is running it as their little dictatorship. Best I can currently offer you in regards to justice, thus, is to hold the Israeli justice system to account.
I don’t care what side you’re on.
I’m on the side that opposes fascism. I don’t care what language people do fascism in, or what coat of paint they give it. Kahanites and Hamas are the same shit to me.
