Sergey Lavrov is a sophisticated, tough, veteran of world affairs. Rex Tillerson is a dated Colonel Blimp, wooden, artless, way out of his league.
Tillerson: "You must end your support for the Assad regime."
Lavrov: "No"
Tillerson: "Oh, but.... ah... , uhmmmm.... let me get back to you"
U.S. foreign affairs in the hands of the Game Show Host President and Colonel Blimp, what a joke.  Thank God they have Jared Kushner to lend his gravitas to the situation.
