then it’s the territory of what remains of Palestine since Jordan and Israel declared their Sovereign Independence from Palestine in 1946 & 1948. Neither are a part of Palestine, nor is it a part of Lebanon, Syria, Jordan, Egypt or Israel
The US didn’t. The UK didn’t. In fact no state gave Israel recognition as the “Jewish state”. All the official recognitions given were to “the State of Israel” as per the Declaration of the “State of Israel”
This is what the Declaration of the STATE of Israel says “ACCORDINGLY WE, MEMBERS OF THE PEOPLE’S COUNCIL, REPRESENTATIVES OF THE JEWISH COMMUNITY OF ERETZ-ISRAEL AND OF THE ZIONIST MOVEMENT, ARE HERE ASSEMBLED ON THE DAY OF THE TERMINATION OF THE BRITISH MANDATE OVER ERETZ-ISRAEL AND, BY VIRTUE OF OUR NATURAL AND HISTORIC RIGHT AND ON THE STRENGTH OF THE RESOLUTION OF THE UNITED NATIONS GENERAL ASSEMBLY, HEREBY DECLARE THE ESTABLISHMENT OF A JEWISH STATE IN ERETZ-ISRAEL, TO BE KNOWN AS THE STATE OF ISRAEL. “
UNGA Res 181 recognized the RIGHT to have a Jewish State, post 1947. It did not recognize the state, because it did not at that time exist, nor was it’s purpose to recognize it once it did exist. It merely presented recommendations. Recommendations the Jewish Agency accepted.
