サイクス・ピコ協定
Under the secret Sykes–Picot Agreement of 1916, it was envisioned that most of Palestine, when freed from Ottoman control, would become an international zone not under direct French or British colonial control. Shortly thereafter, British foreign minister Arthur Balfour issued the Balfour Declaration, which promised to establish a "Jewish national home" in Palestine, but appeared to contradict the 1915–16 Hussein-McMahon Correspondence, which contained an undertaking to form a united Arab state in exchange for the Great Arab Revolt against the Ottoman Empire in World War I. McMahon's promises could have been seen by Arab nationalists as a pledge of immediate Arab independence, an undertaking violated by the region's subsequent partition into British and French League of Nations mandates under the secret Sykes-Picot Agreement of May 1916, which became the real cornerstone of the geopolitics structuring the entire region. The Balfour Declaration, likewise, was seen by Jewish nationalists as the cornerstone of a future Jewish homeland.
