Propaganda is as easy as the photos you choose and the narratives you spin. Whoever owns the most media, wins.

Certainly, those who have previously caused 54 regime changes and coups, and destroyed whole nations, most recently Libya and Iraq, with Syria and Iran on the shopping list, those Nations DO NOT GET TO LECTURE OTHER NATIONS ON MORALS.
Turkish MP implicates Erdogan administration live on Russian television in sarin gas smuggling to Daesh

The above follows the recent scandal connecting NATO allies Turkey and the US to the ISIS Black Market Oil Trade certainly shold raise eyebrows. Regarding that trade, its non-pipeline tanker haul, protected by Kurdish Peshmerga forces parading as if fighting ISIS around Raqqa and Erbil, but the Kurds are US allies and therefore presumably ISIS allies. I haven't worked it out yet. Erdogan seems unable to co-operate in any means with any Kurd's unless there are laws being broken, because he also brokers some of the oil via Israel, since he has no choice and they all need him, and word on the street is that the Russians are not happy about it. Money talks I guess.
