The president, comparing him to a kid in the back of a classroom, I think, is very indicative of the president's lack of appreciation of who Vladimir Putin is. He's an old KGB colonel that has no illusions about our relationship, does not care about a relationship with the United States, continues to oppress his people, continues to act in an autocratic fashion.
