Washington correspondent for The New Yorker Ryan Lizza examines the way that the Arab Spring has put a spotlight on -- and, in some ways, shaped -- President Obama's foreign policy strategy. Executive Editor of Random House Jon Meacham focuses on the publishing house's decision to rerelease Shelby Foote's "The Civil War," honoring the 150th anniversary of the start of the Civil War. Christy Turlington explains the vulnerability of pregnant women around the world, which she documents in her new film "No Woman, No Cry."
