Spoken like someone completely oblivious to the world around them. Improving relationship with Greece does not mean relationship with Turkey will deteriorate. Politics is not a zero sum game. India has maintained a balance between United States and USSR for years, without having to devote itself completely to either camp. Why develop relationship with Israel when China has relationship with Arab states? According to you there would be no need.
Turkey has China by the throat? If you get anymore moronic, you can probably register yourself for mental health income assistance. The number of Han in Xinjiang is roughly equal to that of Uyghurs, and has been growing for decades. Uyghurs represent less than 1/100 of China's total population. ETIM is essentially storm in a tea cup, and only survived because of Turkish support. Having good relationship with Greece also sends the message to Turkey they cannot support Xinjiang seperatists without reprecussion, get it?
News flash, United States already have bases in Turkey. If you bothered to check reality once in a while, you'd know that.
