Bad example. It was Israel's land, and the original nations no longer exist, and there was no Palestine state, and the British gave land for a Jewish state, and the Muslims refused a deal that would have given them this:

Let me get this straight. The Brits take the lands from the Ottoman Empire, and then decides to give it to the Jewish refugees from the Holocaust without asking the Arabs living on it if they want that? It would be akin to the UN/IMF taking over the US after a financial collapse and then decide to return TX, AZ. NM, CA to Mexico without asking the Americans living in those states. Recipe for trouble recipe for trouble. The last 60 plus years affirmed it. Brits screw up and we are dumb to assume the mantle along with all the headaches.
