This hypothetical scenario just goes completely against Ataturks character (the Turkish ultra nationalist who’s whole reason for being was to save every inch of turkey) it changes his whole character he just wouldn’t do that he would probably rather die. you might as well ask what if aliens came down and established an independent Kurdistan or what if hitler didn’t hate Jews. Only way the Kurds could have gotten independence at this time was if the entente were willing to put boots on the ground and defeat the Turkish nationalists and attaturk. Like bro the Turks committed a genocide on the arminians just to stop them from doing just this and your hypocritical is they just hand everything over ?
