The immediate post-World War II era was undeniably a period of American power and influence. Even during the Cold War, the United States was the leader of the West, exerting wide-ranging power internationally. But beginning with the Vietnam War, America began experiencing a series of setbacks and challenges to its power. examines how U.S. presidents have attempted to reverse or contend with this new era of limited power in which presidential leadership is hamstrung due to an increasingly globalized and interdependent world—one where power is more diffuse and the system of checks and balances bind a president in an age of hyper-partisanship. The book examines presidents of the 20th and 21st centuries, explaining how the first U.S. president to confront this new age was Richard Nixon, who—along with Henry Kissinger—developed a sophisticated approach to deal with the recalibration of American power. It documents how other recent presidents have either tried to make peace with limited power (Jimmy Carter), reverse the decline (Ronald Reagan), ignore the implications of limits (George W. Bush), or find ways to lead that were less ambitious, more prudent, and less unilateral (George H.W. Bush, Bill Clinton, and Barack Obama). In the cases of Clinton and Obama, this shift to using "soft power," persuasion, and multilateralism earned them criticism that they are "weak," thereby undermining their efforts to lead—both at home and abroad.
