Erikn, to find the answer to your question about how the Brits could give part of Israel's land away in 1922 before the state of Israel existed, you need to study the League of Nations' British Mandate and all related international agreements at that time. The land the Brits gave to the Hashemites was designated as part of the Jewish homeland. The Brits violated the Mandate as well as their own policies for the purpose of placating the Hashemites and preventing them from going to war against the French in Syria. Giving that land to the Hashemites was for appeasement purposes only. It was a consolation prize for the Hashemite brothers losing Syria. Instead, they were handed (or gifted) Jordan and Iraq.
