The status of the United States as a world power, and the nature of power itself, are at a historic turning point. It is essential that we understand and adapt to the new security environment in which we find ourselves.

Two of the most respected figures in American foreign policy are Zbigniew Brzezinski and Brent Scowcroft -- both former National Security Advisors under markedly different administrations. In America and the World they dissect, in spontaneous and unscripted conversations moderated by David Ignatius, the most significant foreign policy challenges facing the U.S.: the Middle East, Russia, China, Europe, the Developing World, the changing nature of power in a globalized world, and what Brzezinski has called the "global political awakening." While one author is a Republican and the other a Democrat, they broadly agree on the need to adapt to a new international environment. Where they disagree, their exchanges are always both deeply informed and provocative.

America and the World will define the center of responsible opinion on American foreign policy at a time when the nation's decisions could determine how long it remains a superpower.
