An interesting article by David Rieff:
Policy analysts and pundits have been predicting for some time that the so-called unipolar moment, in which the United States stands unchallenged as the sole superpower, will soon come to an end. The debacle in Iraq has hastened this reckoning and sharpened the anxieties about America’s role in the world — perhaps especially among those who believe that the United States is a benign hegemon and that the real choice is between a Pax Americana and anarchy. But it is the recent conduct of Hugo Chávez, Venezuela’s firebrand president, that offers the starkest evidence yet of the changed circumstances that American policy makers are starting to confront around the world.
