Not all of them are al nusra. But many are.
That’s the other lie. That they are members of this, or that. Al Qeida, Al Nusra, ISIS, FSA, etc etc. There are actually over 50 groups “vetted” and listed.
They freely move from one to the other as one becomes hot, or falls out, or back into favor.
They are all head choppers, that have all moved slowly under the giant CIA State Dept umbrella of Syrian Democratic Forces or whatever they call it this week.
DC loves to obscure things with this shell game. They deflect criticism by saying “Oh, that ZYX is a completely different group, WE support the XYZ”.
They Syrian Farce.
