Nicholas Burns said on one of the seditious MSM chatter shows today that Russia is not attacking IS in Syria. This is utterly untrue and a standard propaganda meme of the neocons, of which he is obviously one. Russian aircraft have been deeply involved in all SAA operations aimed to re-take Palmyra. Russian aircraft have been deeply involved in the defense of the Deir al-Zor pocket 200 kilometers east of Palmyra. Who does Burns think that the Russians are fighting out there in the east? Is it the FSA unicorns of fabled semi-existence that Burns thinks are besieging Deir al-Zor or who captured Palmyra a month or so back.
My sources inform me that US/Russia tactical coordination in Syria is now well advanced and effective.
I doubt that Burns is that ignorant. IMO he is merely an opportunist who hopes for a neocon restoration in US foreign policy. pl
