Today, even as it asserts itself globally, America lacks a grand strategy to replace the Cold War's 'containment of communism'. In this visionary book, Gary Hart, until recently co-chair of the U.S. Commission on National Security in the 21st Century, outlines a new principled approach, based on the power of American ideals, its 'fourth power'. Constitutional liberties, representative government, press freedom, and democratic principles, he argues, constitute a resource which is attractive to peoples worldwide, and may prove as important to national security as the three traditional powers -- military, economic, and political might.
