That’s an oversimplification I think. The UN is one of the tools used to maintain and legitimise the liberal world order. Of course it’s not our tool, in a just (socialist) world order Israel would not exist.
What’s significant is that the fascists in Tel Aviv are telling everyone that they cannot be trusted to exist in the liberal world order either. And that the way to square that circle is to tear down the order.
That is not by itself the material change we want to see, but it is significant. The majority of actual decision makers in the world are libs, and they’re not immune to ideology. And nothing riles up libs quite like shaking the boat. They have their own troubles at home with the unacknowledged recession, climate change, disillusionment with the status quo etc.
This is not by itself the change we want to see, but I’m optimistic it can be the political environment in which that change can occur.
