American primacy continues to characterise the international system, despite trends toward a diffusion of power. The discussion is too often biased in favour of multipolarity due to imprecise or misleading definitions of US primacy. On the basis of a simple definition of what a "pole" is, combining GDP and defence expenditure, only the US can be considered a global pole. The current economic crisis is not changing this reality. Even considering perceptions, soft power, and the ability to translate power into influence, rising powers like China or an aggregate power like the EU have a long way to go before they can get on an equal footing with the United States.
