Agreed, which is why the fact that Israel has been called to international court multiple times on war crimes, human rights violations, and terrorism is so damning. More so since they refuse to defend themselves in court.
So in that regard I wish the UN would act.
But they wont because there is no international law, there is no enforcement, they cant act, they arent a government. It is up to the individual countries to choose to act or not when the UN decrees a thing.
