Augy is totally right about the West, they obviously don't want the PKK Kurds to win. They would gladly support those in Iraq, but the Kurds from Syria have strong relations with the PKK, and the PKK has been struggling against Ankara for a very long time. It's not just that they are somewhat communists, they are above all Kurdish. Moreover Turkey is a NATO country, so of course the West can't just send weapons to the PKK and its allies. If those guys were "moderate" jihadists, or "opposition" as they call them on the BBC, they would have sent them money, weapons, food... and probably trained them in Turkey.
