International relations and political science are my professional areas of teaching and research. I draw on this authority to strongly recommend the following article for your reading. Charles Krauthammer's "Decline Is a Choice: The New Liberalism and the end of American ascendancy."Among other things, he says:
.... my thesis is simple: The question of whether America is in decline cannot be answered yes or no. There is no yes or no. Both answers are wrong, because the assumption thatsomehow there exists some predetermined inevitable trajectory, the result of uncontrollable external forces, is wrong. Nothing is inevitable. Nothing is written. For America today, decline is not a condition. Decline is a choice. Two decades into the unipolar world that came about with the fall of the Soviet Union, America is in the position of deciding whether to abdicate or retain its dominance. Decline--or continued ascendancy--is in our hands.
Not that decline is always a choice. Britain's decline after World War II was foretold, as indeed was that of Europe, which had been the dominant global force of the preceding centuries. The civilizational suicide that was the two world wars, and the consequent physical and psychological exhaustion, made continued dominance impossible and decline inevitable.
The corollary to unchosen European collapse was unchosen American ascendancy. We--whom Lincoln once called God's "almost chosen people"--did not save Europe twice in order to emerge from the ashes as the world's co-hegemon. We went in to defend ourselves and save civilization. Our dominance after World War II was not sought. Nor was the even more remarkable dominance after the Soviet collapse. We are the rarest of geopolitical phenomena: the accidental hegemon and, given our history of isolationism and lack of instinctive imperial ambition, the reluctant hegemon--and now, after a near-decade of strenuous post-9/11 exertion, more reluctant than ever.
