The concept of Jordan as a Palestinian state is not new.
BREITBART -- Historically, various proposals have suggested Jordan’s involvement in resolving the Israeli-Palestinian conflict, with the argument that “Jordan is Palestine” being a recurring topic primarily based on historical, geographical, and political perspectives.
Historically, the British Mandate for Palestine, established after World War I, originally included the territory of both modern-day Israel and Jordan. The mandate incorporated the Balfour Declaration of 1917, which expressed Britain’s support for a “national home for the Jewish people” in Palestine.
In 1922, the British divided the mandate into two administrative areas: west of the Jordan River, which became the Jewish national home (later, Israel); and east of the Jordan River, which eventually became the Hashemite Kingdom of Jordan. Those on the east bank, just as the Jews and Arabs on the west bank, were considered Palestinians, subject to British control and carriers of Palestinian passports.
