Richard Haass's "The Age of Nonpolarity," in Foreign Affairs, and the "Phoenix Initiative" on the American role in the world, led by prominent advisers to Barack Obama during his campaign, both pick up on the theme that the international order is increasingly defined by transnational forces beyond the control of single states and that American exceptionalism is somehow outdated.
