Join SAJA for a live web radio discussion with Parag Khanna, whose new book is "The Second World: Empires and Influence in the New Global Order." The book was excerpted as a provocative Jan. 2008 cover story in the New York Times magazine as "Who shrunk the Superpower?" He looks at how societies struggle to manage the pressures of globalization and how they respond to the competing influences of the leading superpowers: the United States, European Union, and China.
