"For the US power elite, being on top of the world has been a habit for 60 years. Hegemony has been a way of life; empire, a state of being and of mind. The institutional realist critics of the Bush administration have no alternative conceptual framework for international relations, based on something other than force, the balance of power or strategic predominance. The present crisis and the deepening impact of global concerns will perhaps generate new impulses for cooperation and interdependence in future. Yet it is just as likely that US policy will be unpredictable: as all post-colonial experiences show, de-imperialisation is likely to be a long and possibly traumatic process."
