Hegemony and empire are different words that offer widely distinct interpretations of the power of the United States and their contemporary manifestations, and how this power can be changed. After a brief introduction about both words, we will show how hegemony can be spatially understood and, in this way, how difficult it is for the hegemony of the United States to be channelled in an empire, pointing out the political-military American fiasco in Iraq in spite of her apparent military supremacy after the Cold War. Finally, we will consider the emergency of a new configuration of global power where the hegemony no longer can be exclusively associated to the United States. The underlying central subject is the need to flee the trap of thinking power exclusively in territorial terms: States versus empires. The power grows spatially in much more complex ways and we needed to understand it if we want to question it.
