"There is a madness in Gaza now." So says New York Times Jerusalem bureau chief Steven Erlanger, who joins Terry Gross to talk about the Palestinian power struggle that's erupted recently and how the battles between the Hamas and Fatah factions are affecting life in the West Bank and Gaza.

Erlanger has reported from all over the world, serving in Moscow, Bangkok, Prague and other cities. Prior to his tenure at the Times, he wrote for The Boston Globe.

Natasha Trethewey was awarded the Pulitzer Prize for Native Guard, her most recent collection of poetry. The title refers to a regiment of African- American soldiers who fought for the Union in the Civil War.

Trethewey grew up the child of a racially mixed marriage in Mississippi. Her mother was murdered by her stepfather; these, along with the South and its singular ways, are recurring themes in her poetry.

Trethewey teaches creative writing at Emory University. Native Guard is her third collection.

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.

British singer-songwriter Bryan Ferry is probably best known as the frontman for Roxy Music, the experimental synth-pop band he founded in 1971.

But over the years, in between his Roxy music, he's recorded albums devoted to songwriters he admires.

The latest? It features his takes on tunes from "Simple Twist of Fate" to "Make You Feel My Love," and it's called Dylanesque.
