Anthony Bourdain's television travelogue "Parts Unknown" goes to Iran to discover how people live behind the geopolitical smoke screen and to small-town Massachusetts to chronicle the heroin scourge. But even if the fourth season of his Emmy Award-winning CNN show fosters cultural diplomacy or raises drug awareness, this outspoken New York chef insists he is on no kind of socially minded mission. 

CNN food and travel host Anthony Bourdain's excellent hour-long special on Israel-Palestine, in he which he explores both sides of the green line, begins with a line that could not ring truer for me. "It's easily the most contentious piece of real estate in the world. And there's no hope – none – of ever talking about it without pissing somebody, if not everybody, off," he says of Israel-Palestine and particularly Jerusalem.
