Uh, not everyone believes that appearing on tv channel, or in a magazine or newspaper, or with an interviewer, who advocates or believes in things you think are wrong, is always a problem. For some of us political figures being willing to engage with all kinds of people, both at home and abroad, is not only ok, but desirable.
Seriously, I would not think the leaders of Saudi Arabia, or China, or any other place were somehow undermining their own views because they appeared on some western tv station.
