Amy Chua, "The Rise and Fall of Hyperpowers"

The U.S. is the seventh hyperpower in history. Yale Law School’s John Duff Jr. Professor of Law Amy Chua, author of Day of Empire, visits Zócalo to discuss the extraordinary hyperpowers of the past and the fate of the American power in the 21st century.
