"For many American leftists, comrades abroad who ask for help are a nuisance; they interfere with our self-absorption. There is a leftist argument, sometimes articulated, more often assumed, which holds that America, the global hegemon, is responsible for most of the bad things that happen in the world. The task of the American left, therefore, is to oppose the activist policies of the hegemon and press for U.S. disengagement from international politics. America is the agent that counts in the world, and we (leftists) are the necessary opposition. Everything else is just peripheral noise.
It is very difficult to acknowledge that there are other agents in the world who are responsible, entirely on their own, for bad things."
