America's post Cold War footprint is an anachronism.
Thomas Barnett ponders the difference:
'The pursuit of primacy as a grand strategy is completely un-American in both its conception and execution. In fact, the Bush-Cheney neocons brought us far closer to an ideological coup d'état than any previous foreign policy scandals of note, including the secret wars of Nixon and Reagan. America's clear and succinct grand strategy, first enunciated by Presidents William McKinley and Theodore Roosevelt when the U.S. was coming of age as a great power, has been the "open door." Primacy was never its prize or its purpose.Instead, the goal was to end Europe's corrupt colonialism through the extension of our model of multinationalism based on states united, economies integrated and security provided for collectively. In this model, no one state is allowed primacy over the union's other members. Conversely, no one state's economic success is viewed as a zero-sum loss by the others, for all find ultimate benefit in the shared economic connectivity....
If the "2.0 revolutions" of North Africa tell us anything, it's that America remains firmly on the side of the transformational future, unlike China and the rest of the authoritarian ranks. More to the point, America cannot be the world's most-consistent revisionist power and, at the same time, the keeper of any empire. Indeed, when it comes to the great empires of the 20th century, America played a profound role in dismantling all of them. On this score, Vladimir Lenin and Mao Zedong combined can't hold a candle to Franklin Roosevelt.

I think this is a point that very frequently gets over-looked in the debates about American military spending and role in the world: the post Cold War defense build-up and global posture was in response to the rise of the Soviet Union and collapse of power centers in Asia and Europe. That posture and the over-sized military that sustains it was never meant to be an end in itself.
