I’m surprised that you are buying the Turk propaganda that all the Kurds fighting ISIS are terrorists. I think you should look into this a little more.
Erdogan decided to bomb the Kurd forces in Syria not because they are “terrorists” but because the Kurds recently made gains in the Turkish parliament that threaten Erdogan’s parties majority. He is trying to provoke a Kurdish response inside Turkey so that the Kurdish political party will lose at the polls. It’s all about keeping him in power.
PS As I said to BG. Two wrongs don’t make a right.
