When the National Command Authority displays an inherent lack of any clear, concise and coherent national level strategy for just about anything other than his/their whim of the moment moves...you get massive "cross talk" and nothing goes anywhere.....
CENTCOM backs PYD/YPG to the hilt, empowering it to consider self-ruled zone.
State Dept. insists no territory would receive recognition.
AND Turkey has openly declared any Kurdish self rule zone on their border is a total red line and that they would hinder it...appears to have been completely overlooked/overheard.....
What has been amazing to me in this whole debate around IS is the simple fact that US has had a large Arab Sunni Syrian army made up of Syrian Sunni's more than willing to take on IS and in fact have done so for over three years AND the NCA and CENTCOM totally ignores them under the guise of "they are not moderate enough for us"....or "we cannot determine who is or is not moderate enough for us"......
Who the heck cares how "moderate" a group is or is not as long as they are willing to take on IS in their own country.....then we just need to sit back and let them work it out....which in the end the Syrian civil society is fully capable of doing on it's own....
If one is intently watching Syria right now this is exactly what is ongoing with the AQ group JaN trying to push out true moderate FSA forces in Ibid and being openly challenged rather successfully by the "Syrian street" demonstrations that forced them to pull back....
