Why were the three documents by Britain and France during world war 1 which caused the later trouble in Palestine?

The three key documents—namely the Balfour Declaration (1917), the Sykes-Picot Agreement (1916), and the Hussein-McMahon Correspondence (1915)—created conflicting promises regarding the future of Palestine and the wider Arab territories. The Balfour Declaration supported a Jewish national home in Palestine, while the Sykes-Picot Agreement divided the region into zones of British and French control, contradicting promises made to Arab leaders for independence. These contradictions fueled tensions between Jewish and Arab communities and laid the groundwork for future conflicts in the region. The failure to reconcile these commitments contributed significantly to the ongoing strife in Palestine.
