I see part of the problem you’re having, “The Mandate” was not a physical entity as you seem to imagine it. It was an administrative order. You can find the details here: The Avalon Project : The Palestine MandateWhen the Mandate left the UN ducked out. What then would be Palestine's status? Does that mean that Palestine was up for grabs?After the termination of the Mandate, Palestine (the territory to which the Mandate Applied) continue to be a legal entity. Why? (RHETORICAL) It will still not be a sovereign state because it will not be immediately self-governing.
What was “Palestine’s” status before the Turks released all rights and title? Well, there was no “Palestine” under the Ottoman Empire. I would suggest you look at YouTube videos for a comprehensive description.
Anything on those “new states” conspiracy theory?
