Not so much personal as out in the open.
Well, that kinda depends on Russia's proof. Smuggling is a way of life almost everywhere, in one form or another. There is little doubt that Daesh oil is smuggled into Turkey, Syria, Iran, Iraq and probably elsewhere.
But with the most recent comments, Russia is hanging it specifically onto Erdogan and his family. They are not only calling him out as a political leader, but as a man.
That is not de-escalation. haha
