No. The only organ that can make “binding” decisions is the security council. Unfortunately all decisions (except for administrative questions) need the approval of china, russia, the UK, France aaand the US. So I doubt that tha the US will ever sanction Israel because it would mean they are admitting to supporting war criminals.
I used to think that believes really don’t matter as long as the person doesn’t act on it, but almost all believes shape who we are. It starts with little comments and evolves into actions. It doesn’t have to be that way if people acknowledge harmful ideas, but if you let someone believe that women are worthless or that their race makes them superior for long enough they will become a bad person.
