Blind men and women have been the motor of modern history and the source of endless misery and destruction. Aspiring leaders of great powers can neither understand nor admit the fact that their strategies are extremely dangerous because statecraft by its very nature always calculates the ability of a nation’s military and economic resources to overcome whatever challenges it confronts. To reject such traditional reasoning, and to question the value of conventional wisdom and react to international crises realistically on the basis of past failures would make them unsuited to command. The result is that politicians succeed in terms of their personal careers, states make monumental errors, and people suffer. The great nations of Europe and Japan put such illusions into practice repeatedly before 1945.
At the beginning of the 21st century only the U.S. has the will to maintain a global foreign policy and to intervene everywhere it believes necessary. Today and in the near future, America will make the decisions that will lead to war or peace, and the fate of much of the world is largely in its hands. It thinks it possesses the arms and a spectrum of military strategies all predicated on a triumphant activist role for itself. It believes that its economy can afford interventionism, and that the American public will support whatever actions necessary to set the affairs of some country or region on the political path it deems essential. This grandiose ambition is bipartisan and, details notwithstanding, both parties have always shared a consensus on it.
