Well, I for one am glad that fact has been clarified. YPG/PKK/PYD, work alongside the Americans and they are traitors to Syria. They were NEVER the best or fiercest fighters against ISIS!
"In response to a question about the actions of Kurds in the eastern area and their cooperation with the Americans, President al-Assad said that it’s not right to say that a Syrian group – whether ethnic or religious – has a uniform characteristic, because this makes no sense since all groups are diverse, and the various groups in Syria have the good and the bad, so talking about “Kurds” is imprecise as there are various groups in the eastern region working with foreign sides, specifically the Americans.
“This isn’t me saying that; they declare that they work under cover of the American warplanes and in coordination with them. They marketed and published photos and videos about this issue. All those who work under the command of any foreign country in their own country and against their army and people are traitors, quite simply, regardless of their names, and that is our evaluation of the groups that work for the Americans in Syria,” the President said."
