"When considered over the longer term, as in this monograph, U.S. foreign policy, national security policy, and strategy must reconcile the demands of a domestic culture that can have dysfunctional consequences abroad, with the objective circumstances of the outside world. It is almost entirely useless for American or other scholars to write books and articles urging a U.S. policy that affronts American culture. [...]. To be sustainable, American policy and strategy must be broadly compatible with American values. Perhaps not all American values, and not all of the time. But any policy vision that is plainly un-American is certain to fail at home eventually. Foreign policy is born at home and has to succeed there if it is to succeed abroad. The current debate to which this monograph relates is replete with arguments about anticipated features of the 21st century that will prove desperately challenging to American national culture. It may well be that this century will see a return of multipolar balance-of-power politics on a global scale. [...].. The body of this work opens with an explanation of the structure of the subject of national security strategy; it then attempts to peer into the future to identify assumptions that should be robust, albeit with caveats attached. Next, the discussion specifies the most desirable American role in the world of the 21st century. From the American role, the analysis moves on to consider the most appropriate strategy. The monograph closes with observations and recommendations on national security strategy."
