Though the US and it's western allies are shedding crocodile tears for Kurds separate autonomous region, hoping that they can divide Syria and protect Isreal, by making all it's neighbours weak, divided, engaged in civil war internally, and maintain their influence too against Russia and Iran, and benefit from the resources of the land, they will never go as far as to antagonising Turkie and driving it away towards Russia and Iran, china. With Russia, China, Iran, Turkey together, the west would become weak and lose, their authority, power, influence to control or manipulate countries in middle east, they may probably have to retreat from every country that thet are holding bases now, as countries realise that their power is wading and they are mere paper tigers now, Asian countries may be except Japan and Taiwan, Africa, and middle east together, the west would lose all its hegemony, heroism of bribing the ruling elites, using human rights violation, equal rights, authoritarian rule, dictatorship to change regimes, in the pretext of providing security, selling their weapons looting their resources etc., so if any one is believing that US would kill Turks to defend Rojava is living in fools paradise, US is well known for ditching states and groups when they realise that they are of no use any more to serve their purpose, so the SDF too may learn this lesson soon.
