Americans lived in a “victory culture ” for much of the twentieth century. You could say that we experienced an almost 75-year stretch of triumphalism — think of it as the real “American Century” — from World War I to the end of the Cold War, with time off for a destructive stalemate in Korea and a defeat in Vietnam too shocking to absorb or shake off.
When the Soviet Union disintegrated in 1991, it all seemed so obvious. Fate had clearly dealt Washington a royal flush. It was victory with a capital V. The United States was, after all, the last standing superpower, after centuries of unceasing great power rivalries on the planet. It had a military beyond compare and no enemy, hardly a “rogue state,” on the horizon. It was almost unnerving, such clear sailing into a dominant future, but a moment for the ages nonetheless. Within a decade, pundits in Washington were hailing us  as “the dominant power in the world, more dominant than any since Rome.”
And here’s the odd thing: in a sense, little has changed since then and yet everything seems different. Think of it as the American imperial paradox: everywhere there are now “threats” against our well-being which seem to demand action and yet nowhere are there commensurate enemies to go with them. Everywhere the U.S. military still reigns supreme by almost any measure you might care to apply; and yet — in case the paradox has escaped you — nowhere can it achieve its goals, however modest.
At one level, the American situation should simply take your breath away. Never before in modern history had there been an arms race of only one or a great power confrontation of only one. And at least in military terms, just as the neoconservatives imagined  in those early years of the twenty-first century, the United States remains the “sole superpower” or even “hyperpower” of planet Earth.

And yet the more dominant the U.S. military becomes in its ability to destroy and the more its forces are spread across the globe, the more the defeats and semi-defeats pile up, the more the missteps and mistakes grow, the more the strains show, the more the suicides rise , the more the nation’s treasure disappears  down a black hole — and in response to all of this, the more moves the Pentagon makes.
