Second Chance: Three Presidents and the Crisis of American Superpower is a 2007 book by Zbigniew Brzezinski, who was President Carter's National Security advisor and a scholar of American foreign policy as a professor at the School of Advanced International Studies at Johns Hopkins University. The book discusses the 15 years of American foreign policy where the U.S., emerging as the "victor" in the Cold War, has been the lone "superpower." Brzezinski writes about how United States presidents George H. W. Bush, Bill Clinton, and George W. Bush have demonstrated leadership and wielded power throughout a decade and a half as the leaders of a virtually unchallenged world power. Source: Wikipedia (en)
