Or, even better, the beginning of Isreal's transformation into a country where people see through the bullshit of the far-right and elect decent leaders, leaving Netanyahu to rot in prison.
You're right. Given demographic changes in the US, I do think it's only a matter of time before most Americans consider Israel to be an albatross around their necks.
Oh fuck off, Israel and their global backers are continuing their century-long campaign to take Palestine and remove/kill Palestinians. Hamas is just a recent development which happens to neatly justify this period of Israeli colonial violence.
After Hamas runs its course (however that ends up happening), then do you think Israel will back off? Of course not and the idea is preposterous.
The world court can do two things. First, arbitrate between two consenting states who agree to abide by the decision. Second, issue advisory rulings which have absolutely no functional authority. America doesn't have to step in. Nation states around the world wouldn't have signed onto a world court that could actually compel them to obey, we all like our sovereignty.
