The purpose of this chapter is first to analyze the international legal definition of genocide, but how the term can still be ambiguous. Then this chapter analyzes the three waves of genocide against the Kurds in Syria: (1) The earlier Arab/Baathist phase was highlighted by the notorious Decree 93 in 1962, which stamps many Kurds in Syria as ajanib who could not vote, own property or work in government jobs. (2) More recently, the ISIS genocidal attack against the Kurds in 2014, was emphasized by the dramatic battle of Kobane, which eventually brought in U.S. aid to help defeat ISIS. (3) The Turkish attacks with their Jihadists allies that began in Kurd Dagh (Afrin) in 2018 and continued with renewed attacks in following years to the east in attempts to remove the Kurds from the Turkish border and continues to this day offer yet another example of genocide against the Kurds in Syria. Finally, this chapter also argues that when certain acts may have fallen short of what some might legally label as genocidal, the term ethnic cleansing might be more appropriate.
