The rise and fall of great powers and their imperial domains has been a central fact of history for centuries. It’s been a sensible, repeatedly validated framework for thinking about the fate of the planet. So it’s hardly surprising, when faced with a country once regularly labeled the “sole superpower,” “the last superpower,” or even the global “hyperpower” and now, curiously, called nothing whatsoever, that the “decline” question should come up. Is the United States or isn’t it? Might it or might it not now be on the downhill side of imperial greatness?

Take a slow train—that is, any train—anywhere in America, as I did recently in the northeast, and then take a high-speed train anywhere else on Earth, as I also did recently, and it’s not hard to imagine the United States in decline. The greatest power in history, the “unipolar power,” can’t build a single mile of high-speed rail? Really? And its Congress is now mired in an argument about whether funds can even be raised to keep America’s highways more or less pothole-free.

Sometimes, I imagine myself talking to my long-dead parents because I know how such things would have astonished two people who lived through the Great Depression, World War II, and a can-do post-war era in which the staggering wealth and power of this country were indisputable. What if I could tell them how the crucial infrastructure of such a still-wealthy nation—bridges, pipelines, roads, and the like—is now grossly underfunded, in an increasing state of disrepair, and beginning to crumble? That would definitely shock them.

And what would they think upon learning that, with the Soviet Union a quarter-century in the trash bin of history, the United States, alone in triumph, has been incapable of applying its overwhelming military and economic power effectively? I’m sure they would be dumbstruck to discover that, since the moment the Soviet Union imploded, the United States has been at war continuously with another country (three conflicts and endless strife); that I was talking about, of all places, Iraq; and that the mission there was never faintly accomplished. How improbable is that? And what would they think if I mentioned that the other great conflicts of the post-Cold-War era were with Afghanistan (two wars with a decade off in between) and the relatively small groups of non-state actors we now call terrorists? And how would they react on discovering that the results were: failure in Iraq, failure in Afghanistan, and the proliferation of terror groups across much of the Greater Middle East (including the establishment of an actual terror caliphate) and increasing parts of Africa?

They would, I think, conclude that the United States was over the hill and set on the sort of decline that, sooner or later, has been the fate of every great power. And what if I told them that, in this new century, not a single action of the military that US presidents now call “the finest fighting force the world has ever known” has, in the end, been anything but a dismal failure? Or that presidents, presidential candidates, and politicians in Washington are required to insist on something no one would have had to say in their day: that the United States is both an “exceptional” and an “indispensible” nation? Or that they would also have to endlessly thank our troops (as would the citizenry) for…well…never success, but just being there and getting maimed, physically or mentally, or dying while we went about our lives? Or that those soldiers must always be referred to as “heroes.”

In their day, when the obligation to serve in a citizens’ army was a given, none of this would have made much sense, while the endless defensive insistence on American greatness would have stood out like a sore thumb. Today, its repetitive presence marks the moment of doubt. Are we really so “exceptional”? Is this country truly “indispensible” to the rest of the planet and if so, in what way exactly? Are those troops genuinely our heroes and if so, just what was it they did that we’re so darn proud of?

Return my amazed parents to their graves, put all of this together, and you have the beginnings of a description of a uniquely great power in decline. It’s a classic vision, but one with a problem.

A God-Like Power to Destroy

Who today recalls the ads from my 1950s childhood for, if I remember correctly, drawing lessons, which always had a tagline that went something like: What’s wrong with this picture? (You were supposed to notice the five-legged cows floating through the clouds.) So what’s wrong with this picture of the obvious signs of decline: the greatest power in history, with hundreds of garrisons scattered across the planet, can’t seem to apply its power effectively no matter where it sends its military or bring countries like Iran or a weakened post-Soviet Russia to heel by a full range of threats, sanctions, and the like, or suppress a modestly armed terror-movement-cum-state in the Middle East?

For one thing, look around and tell me that the United States doesn’t still seem like a unipolar power. I mean, where exactly are its rivals? Since the fifteenth or sixteenth centuries, when the first wooden ships mounted with cannons broke out of their European backwater and began to gobble up the globe, there have always been rival great powers—three, four, five, or more. And what of today? The other three candidates of the moment would assumedly be the European Union (EU), Russia, and China.

Economically, the EU is indeed a powerhouse, but in any other way it’s a second-rate conglomeration of states that still slavishly follow the United States and an entity threatening to come apart at the seams. Russia looms ever larger in Washington these days, but remains a rickety power in search of greatness in its former imperial borderlands. It’s a country almost as dependent on its energy industry as Saudi Arabia and nothing like a potential future superpower. As for China, it’s obviously the rising power of the moment and now officially has the number one economy on planet Earth. Still, it remains in many ways a poor country whose leaders fear any kind of future economic implosion (which could happen). Like the Russians, like any aspiring great power, it wants to make its weight felt in its neighborhood—at the moment the East and South China Seas. And like Vladimir Putin’s Russia, the Chinese leadership is indeed upgrading its military. But the urge in both cases is to emerge as a regional power to contend with, not a superpower or a genuine rival of the United States.

Whatever may be happening to American power, there really are no potential rivals to shoulder the blame. Yet, uniquely unrivaled, the United States has proven curiously incapable of translating its unipolar power and a military that, on paper, trumps every other one on the planet into its desires. This was not the normal experience of past reigning great powers. Or put another way, whether or not the United States is in decline, the rise-and-fall narrative seems, half a millennium later, to have reached some kind of largely uncommented upon and unexamined dead end.

In looking for an explanation, consider a related narrative involving military power. Why, in this new century, does the United States seem so incapable of achieving victory or transforming crucial regions into places that can at least be controlled? Military power is by definition destructive, but in the past such force often cleared the ground for the building of local, regional, or even global structures, however grim or oppressive they might have been. If force always was meant to break things, it sometimes achieved other ends as well. Now, it seems as if breaking is all it can do, or how to explain the fact that, in this century, the planet’s sole superpower has specialized—see Iraq, Yemen, Libya, Afghanistan, and elsewhere—in fracturing, not building nations.

Empires may have risen and fallen in those 500 years, but weaponry only rose. Over those centuries in which so many rivals engaged each other, carved out their imperial domains, fought their wars, and sooner or later fell, the destructive power of the weaponry they were wielding only ratcheted up exponentially: from the crossbow to the musket, the cannon, the Colt revolver, the repeating rifle, the Gatling gun, the machine gun, the dreadnaught, modern artillery, the tank, poison gas, the zeppelin, the plane, the bomb, the aircraft carrier, the missile, and at the end of the line, the “victory weapon” of World War II, the nuclear bomb that would turn the rulers of the greatest powers, and later even lesser powers, into the equivalent of gods.

For the first time, representatives of humanity had in their hands the power to destroy anything on the planet in a fashion once imagined possible only by some deity or set of deities. It was now possible to create our own end times. And yet here was the odd thing: the weaponry that brought the power of the gods down to Earth somehow offered no practical power at all to national leaders. In the post-Hiroshima-Nagasaki world, those nuclear weapons would prove unusable. Once they were loosed on the planet, there would be no more rises, no more falls. (Today, we know that even a limited nuclear exchange among lesser powers could, thanks to the nuclear-winter effect, devastate the planet.)

Weapons Development in an Era of Limited War

In a sense, World War II could be considered the ultimate moment for both the narratives of empire and the weapon. It would be the last “great” war in which major powers could bring all the weaponry available to them to bear in search of ultimate victory and the ultimate shaping of the globe. It resulted in unprecedented destruction across vast swaths of the planet, the killing of tens of millions, the turning of great cities into rubble and of countless people into refugees, the creation of an industrial structure for genocide, and finally the building of those weapons of ultimate destruction and of the first missiles that would someday be their crucial delivery systems. And out of that war came the final rivals of the modern age—and then there were two—the “superpowers.”

That very word, superpower, had much of the end of the story embedded in it. Think of it as a marker for a new age, for the fact that the world of the “great powers” had been left for something almost inexpressible. Everyone sensed it. We were now in the realm of “great” squared or force raised in some exponential fashion, of “super” (as in, say, “superhuman”) power. What made those powers truly super was obvious enough: the nuclear arsenals of the United States and the Soviet Union—their potential ability, that is, to destroy in a fashion that had no precedent and from which there might be no coming back. It wasn’t a happenstance that the scientists creating the H-bomb sometimes referred to it in awestruck terms as a “super bomb,” or simply “the super.”

The unimaginable had happened. It turned out that there was such a thing as too much power. What in World War II came to be called “total war,” the full application of the power of a great state to the destruction of others, was no longer conceivable. The Cold War gained its name for a reason. A hot war between the United States and the USSR could not be fought, nor could another global war, a reality driven home by the Cuban missile crisis. Their power could only be expressed “in the shadows” or in localized conflicts on the “peripheries.” Power now found itself unexpectedly bound hand and foot.

This would soon be reflected in the terminology of American warfare. In the wake of the frustrating stalemate that was Korea (1950-1953), a war in which the United States found itself unable to use its greatest weapon, Washington took a new language into Vietnam. The conflict there was to be a “limited war.” And that meant one thing: nuclear power would be taken off the table.

For the first time, it seemed, the world was facing some kind of power glut. It’s at least reasonable to assume that, in the years after the Cold War standoff ended, that reality somehow seeped from the nuclear arena into the rest of warfare. In the process, great power war would be limited in new ways, while somehow being reduced only to its destructive aspect and nothing more. It suddenly seemed to hold no other possibilities within it—or so the evidence of the sole superpower in these years suggests.

War and conflict are hardly at an end in the twenty-first century, but something has removed war’s normal efficacy. Weapons development has hardly ceased either, but the newest highest-tech weapons of our age are proving strangely ineffective as well. In this context, the urge in our time to produce “precision weaponry”—no longer the carpet-bombing of the B-52, but the “surgical” strike capacity of a joint direct attack munition, or JDAM—should be thought of as the arrival of “limited war” in the world of weapons development.

The drone, one of those precision weapons, is a striking example. Despite its penchant for producing “collateral damage,” it is not a World War II-style weapon of indiscriminate slaughter. It has, in fact, been used relatively effectively to play whack-a-mole with the leadership of terrorist groups, killing off one leader or lieutenant after another. And yet all of the movements it has been directed against have only proliferated, gaining strength (and brutality) in these same years. It has, in other words, proven an effective weapon of bloodlust and revenge, but not of policy. If war is, in fact, politics by other means (as Carl von Clausewitz claimed), revenge is not. No one should then be surprised that the drone has produced not an effective war on terror, but a war that seems to promote terror.

One other factor should be added in here: that global power glut has grown exponentially in another fashion as well. In these years, the destructive power of the gods has descended on humanity a second time as well—via the seemingly most peaceable of activities, the burning of fossil fuels. Climate change now promises a slow-motion version of nuclear Armageddon, increasing both the pressure on and the fragmentation of societies, while introducing a new form of destruction to our lives.

Can I make sense of all this? Hardly. I’m just doing my best to report on the obvious: that military power no longer seems to act as it once did on planet Earth. Under distinctly apocalyptic pressures, something seems to be breaking down, something seems to be fragmenting, and with that the familiar stories, familiar frameworks, for thinking about how our world works are losing their efficacy.

Decline may be in the American future, but on a planet pushed to extremes, don’t count on it taking place within the usual tale of the rise and fall of great powers or even superpowers. Something else is happening on planet Earth. Be prepared.
