The point in the article, it is not a 2 sided conflict in Syria. In Iraq it is also more than 2 sides.
It is less complicated in Iraq, but Iran being the foreign element. Also some presence in Iraq by Turkey (they intend to stay, want the land for oil pipeline).
In Syria there are many factions plus Russian military.
We’ve given very limited support to the Kurds. But we have given support to ISIS and to some of the “rebels”. It appears to me we have supported the “wrong” group of “rebels”, but that is par for Obama, always supporting the “wrong side”.
We tried to train the so called “Rebels’ at a cost of 150 million dollars. We trained 50. They were all dead 14 days after they were released to battle. There is really no distinction between Rebel terrorist and Isis terrorist. The Kurds just fight anyone for territory. They don’t care who. Aleppo got crushed.Raqqa is next. I hope Trump helps the Russians and Assad there. It will be fun to watch. Trump will not allow the press there.
Noone really knows who the Rebels are. McCain had his picture taken with purported Isis and Al Nusra leaders because he had no clue who he was actually meeting with and they all look alike.
