"It is in this sense, then, that it seems almost as if a nuclear weapon went off in New Orleans. The people mostly have fled rather than died, but they are gone. Not all of the facilities are destroyed, but most are. It appears to us that New Orleans and its environs have passed the point of recoverability. The area can recover, to be sure, but only with the commitment of massive resources from outside -- and those resources would always be at risk to another Katrina. The displacement of population is the crisis that New Orleans faces. It is also a national crisis, because the largest port in the United States cannot function without a city around it. The physical and business processes of a port cannot occur in a ghost town, and right now, that is what New Orleans is. It is not about the facilities, and it is not about the oil. It is about the loss of a city's population and the paralysis of the largest port in the United States."
