Yes, this is the important thing to know. I've heard way too many conversations that go back and forth about every act of vengeance in either direction after this, it's all noise. Partition plan started this. But I wouldn't call it an easy way out of responsibility; UK's leaders took a clear and binding position in favor of Zionism.

Also, it was Ottoman territory for hundreds of years up to WWI. I've had friends tell me for some reason about how Palestine was an independent country before... literally wasn't.
