The League of Nations, superseded by the United Nations in 1945. Then there was Resolution 181. The question you have to answer is why the Palestinians have rejected every offer on the table put to them. https://www.britannica.com/topic/United-Nations-Resolution-181
I will start a thread, just for you Steve, to discuss the matter in depth. All the resolutions, mandates, negotiations, wars etc. You can display your in depth knowledge of all these matters including the context, whos, whys and whens. Or, much more likely, it will turn out that all you know about the subject is displayed in the post that I am replying to.
You refer to things like this all the time despite clearly understanding nothing of the subjects you speak of. Who was in the United Nations when 181 passed? How many countries were in the UN? How many Arab states when this vote was held? What were the circumstances, context? There is a lot more to know about the matters you list than simply repeating nonsense. What are all these "offers" that the Palestinians rejected. What is the story? This is why you simply list a few things hoping it demonstrates knowledge-it doesn't. All it demonstrates is that you can repeat the soundbites fed to you by media in the mistaken belief that you are presenting anything coherent rather than following your training.
