[Abstract] In the post-Cold War era, the United States lacks real military advantages to break the global equilibrium; therefore, great power struggle shifts to the economic front. Over-militarization and economic decline quicken the collapse of American hegemonic system. In face of waning power, the country is forced to conduct concentration and support its global role with concert of the major powers. American Middle East policy adjustment, an epitome of global adjustments, may contain: to encourage balance of power to lighten its burden; to recognize Iran as the regional power; to include China in the regional arrangements. American global adjustments will inevitably end up in failure for sake of its disastrous unipolar ambition.
