Russian arms dealer Victor Bout has armed Islamic extremists and sold weapons to some of the Third World's most abusive and murderous dictators and warlords — and he's known for fueling both sides of conflicts.

His success is rooted in the legacy of the Cold War, whose messy unraveling left him with easy access to massive inventories of weapons and ammunition built up by the Soviets. We talk about Bout with journalists Douglas Farah and Stephen Braun, who've co-written a book about him: Merchant of Death: Money, Guns, Planes, and the Man Who Makes War Possible.

Nora Volkow, director of the National Institute on Drug Abuse, ranks as one of the U.S.'s leading addiction researchers. She's helped demonstrate that addiction is in fact a disease — a disease of the brain — and that all addictions, whether it's to drugs, alcohol, tobacco, sex, gambling or even food, are more alike than was previously thought.

Volkow, who's the great-granddaughter of Russian revolutionary Leon Trotsky, grew up in Mexico City — in the house where her famous ancestor was assassinated.

Jonathan Oberlander, a political scientist with an expertise in health-care politics and policy, discusses problems with the U.S. health-care system and considers how other countries handle health care. He'll also give us a critique of Michael Moore's documentary Sicko. Oberlander is an associate professor at the University of North Carolina at Chapel Hill.
