Iran and the U.S.; Elizabeth Gilbert's New Novel; Mao and the Chinese Transformation; the Life of Jane Franklin

On today’s show: former CIA analyst Kenneth Pollack talks about the significance of the more moderate rhetoric that we’ve been hearing from Iran’s president Hassan Rouhani—and whether the US can ever resolve the Iran nuclear question. Elizabeth Gilbert discusses The Signature of Things, her first novel in 13 years. We’ll look at the rise of Mao Zedong and the price that was paid in his attempts to transform the Chinese into “The New People” at whatever cost. Historian Jill Lepore introduces us to Benjamin Franklin’s sister Jane, who was a gifted writer and a shrewd political commentator.
