The interesting part

I was, you know, in a former stage of relation with these guys. They formally called themselves the YPG, who the turks would say equated them to the PKK. Who are dealing with terrorists, enemy of mine, how can you do that ally? So we literally played back them. You gotta change your brand. What do you want to call yourself besides the YPG? With about a day's notice they declared they were the Syrian Democratic Forces. I thought it was a stroke of brains to put democracy in there somewhere, but it gave them a little bit of credibility . And the interesting part , and I was lucky I had a great partner in Brett McGurk out there with me at the same time, because they were asking for things I couldn't give them. And literally that was the acknowledgement that they were the demographic dominant force in northern Sirya. General Raymond Thomas July 2017

It didn’t have to be this way. The U.S. worked endlessly to placate our Turkish allies. We engaged in countless rounds of negotiations, committing to establishing a security mechanism that included joint patrols in areas of concern to the Turks, and deploying 150 additional U.S. troops to help monitor and enforce the “safe zone.” Yet Ankara repeatedly reneged on its agreements with the U.S., deeming them inadequate and threatening to invade SDF-held areas, despite the presence of U.S. soldiers. joseph votel

La costruzione di una fascia di sicurezza è un passo obbligato a tutela dell'interesse nazionale turco.
