The Kurds were born to be betrayed. Almost every would-be Middle East statelet was promised freedom after the First World War, and the Kurds even sent a delegation to Versailles to ask for a nation and safe borders.
But under the Treaty of Sèvres, in 1920, they got a little nation in what had been Turkey. Then along came the Turkish nationalist Mustafa Kemal Ataturk who took back the land that the Kurdish nation might have gained. So the victors of the Great War met in Lausanne in 1922-23 and abandoned the Kurds (as well as the Armenians), who were now split between the new Turkish state, French Syria and Iran and British Iraq. That has been their tragedy ever since – and almost every regional power participated in it. The most brutal were the Turks and the Iraqi Arabs, the most cynical the British and the Americans. No wonder the Turks have gone back to bombing the Kurds.
