British Mandate of Palestine, 1920s. Note: Wasserstein, Bernard (2004). Israel and Palestine: Why They Fight and Can They Stop?, pp. 105–106."Palestine, therefore, was not partitioned in 1921–1922. Transjordan was not excised but, on the contrary, added to the mandatory area. Zionism was barred from seeking to expand there – but the Balfour Declaration had never previously applied to the area east of the Jordan. Why is this important? Because the myth of Palestine's 'first partition' has become part of the concept of 'Greater Israel' and of the ideology of Jabotinsky's Revisionist movement."
