Of course 1922 was before Palestine became a successor state to Turkey. The rules changed after the Treaty of Lausanne.The boundaries of "Palestine" between 1922 and 1948, were not borders, but recognized demarcations of the territory which was subject to the Mandate (Order in Council for Palestine, August 1922).
You are still desperately clinging to the fantasy that the Treaty of Lausanne somehow, magically created your invented “country of Pally’land”.
It didn’t. It’s remarkable that you still attempt to perpetuate that fraud.
