The US must be wondering how wise it is to pull out after Isis is dealt with in the east of Syria given how the Iranians are now embedding in Afrin overnight. Guess it was inevitable though given Erdogans aggressiveness and the US not having any presence to speak of west of the Euphrates. Given Turkeys superior military the YPG in Afrin likely had no choice or they would be run over? So now what... we have to radical Islamist factions up against each other in Afrin and what does this mean for the Kurds in that area?
