This chapter explores the pivotal role of international powers, notably the British Empire and its Allies, in shaping the political landscape of Palestine between 1940 and 1948. The chapter examines how the geopolitical power imbalance, influenced by British colonialism, facilitated the Zionist movement’s agenda at the expense of Arab political and national aspirations. The chapter delves into the strategic interests of the Allies during World War II and the early post-war period, highlighting how these interests intersected with the growing Zionist demand for a Jewish homeland in Palestine. Bsoul analyses the diplomatic manoeuvres, policy shifts, and the eventual withdrawal of British forces to show how the era’s skewed power dynamics led to a significant shift in the region’s struggle for justice and self-determination. The chapter provides a critical analysis of how this imbalance set the stage for the eventual establishment of the State of Israel in 1948, with far-reaching implications for Arab-Zionist relations.
