Power and decline: Why other countries ought to envy the United States

Power and decline: Why other countries ought to envy the United States

A recurring theme in this year’s presidential election is (fear of) American decline, with both candidates seeking to convince voters that they will reverse recent trends and foster an American resurgence. President Obama portrays himself as having repaired some of the self-inflicted wounds imparted by the Bush administration, and he pledges to do still more if reelected. For his part, challenger Mitt Romney promises voters that electing him will ensure that the next 88 years will be an "American Century" just like the last one. Both pitches seek to exploit the lingering fear that America’s best days are behind us.

This is hardly a new concern. Americans seem to have been fretting about losing their mojo ever since World War II. We worried that communism was on the march in the 1950s, saw Sputnik as a grave challenge in the 1950s, and feared becoming a "pitiful, helpless giant" (to use Richard Nixon’s phrase) in the 1970s. During the 1980s, Americans grew anxious about "Japan as #1" and thought we might succumb to "imperial overstretch" that same way Britain had. There was a brief burst of triumphalism following the collapse of the USSR, but it barely lasted a decade. Since 2000, the combination of 9/11, the debacles in Iraq and Afghanistan, and the lingering effects of the financial collapse have reanimated the perennial fear that we are in an irreversible descent.

How seriously should we take this issue? Let’s start by acknowledging that measuring the power of different countries is a very imprecise business, even among professional IR scholars. We don’t have a clear consensus on how to define or measure national power, so we end up using various crude approximations like GNP or more complicated indices that combine GNP, population, military strength, technological capacity, etc. But such measures ignore geography, "soft power," national cohesion, quality of life, etc., and all the other intangibles that can help states to secure their interests and provide both safety and prosperity for their citizens.

Matters get even more complicated when we shift from power to "influence." Power is most usefully conceived as capability — no matter how it is measured — and stronger states can generally do more things and affect others more than weaker states can. But having a lot of power doesn’t translate directly into influence, which is the capacity to get others to do what you want. Sometimes very powerful states can’t convince weaker states to do their bidding, because the weaker powers care more about the issue in question and are willing to make greater sacrifices to get their way. And sometimes even very powerful states lack the capacity to dictate or shape events because the tools they have available aren’t up to the task. Having a lot of power doesn’t enable a country to defy the laws of physics, for example, or guarantee that it can successfully engage in large-scale social engineering in a distant foreign land. Among other things, this is why it is pretty silly to criticize the Obama administration for failing to "control" the Arab spring, as if any U.S. president has the capacity to control a vast and fast-moving social upheaval involving hundreds of millions of people.)

When we think about power, there’s an inevitable tendency to look at trends over time. The question we tend to ask is whether Country X is getting stronger or weaker. Here in America, this approach is usually accompanied by a nostalgic yearning for some by-gone era where the United States was supposedly near-supreme and could do whatever it wanted. Leaving aside the obvious point that things were never really like this, the history of the past century does tend to make Americans more worried than they ought to be.

Why? Because there have in fact been a couple of historical moments when a combination of good fortune and skillful policy put the United States in a highly unusual position of primacy. The United States produced about 50 percent of gross world product in 1945 and had unmatched military power, mostly because the other major economies were mostly in ruins. This was a decidedly unnatural condition, however, and there was nowhere to go but down once the rest of the world recovered from the war. Similarly, the breakup of the USSR and the collapse of Japan’s bubble economy in the early 1990s briefly put the U.S. back on top by a significant margin, and all the more so because other potentially powerful countries (e.g., Japan and the EU) had been free-riding on the US and were punching below their weight.

The point is that relative decline from these two lofty perches was essentially unavoidable, and especially because some less-developed countries like China, India, or Brazil were ideally positioned for rapid growth after 1990. America’s relative decline was accelerated by Bush’s blunders and the financial crisis, but it would have happened anyway regardless of who had been in the Oval office.

There is another way to think about America’s power position, and it ought to give comfort to those who worry that the country is slowly sliding into a position of vulnerability. Just compare the U.S. to other countries today, and ask yourself which states are in the best position to defend their true vital interests (as opposed to all those optional objectives that great powers habitually take on). Which states are masters of their own fates to a considerable extent, instead of having to worry constantly that others might threaten their independence or territorial integrity? Put differently: If you were going to be put in charge of any country’s foreign policy, which country would you pick?

From this perspective things still look pretty good for the United States. It still has the world’s largest and most diverse economy, and its per capita income is much higher than China’s, which means there is more wealth available to mobilize for shared national purposes. It has no serious enemies nearby. It has thousands of nuclear weapons, which means that no state could attack us directly without risking its own destruction. U.S. conventional military forces are far larger than needed to defend American soil, and that remarkable level of territorial security allows U.S. leaders to take on lots of discretionary projects in places like Afghanistan or Yemen or the Phillipines or Africa or Colombia or Libya and to have endless debates about whether we ought to be taking on even more.

The U.S. economy isn’t doing great, of course, but it is performing better than most of the other industrial powers. And despite the current level of partisan rancor and a level of government dysfunction that ought to embarrass us all, there’s virtually no risk of major political upheaval here.

If all we were trying to do was defend Americans against major threats and foster continued economic advancement, running U.S. foreign policy would in fact be relatively easy. The main reason American foreign policy looks difficult is because Washington keeps taking on really difficult objectives, like occupying Iraq, trying to turn Afghanistan into a modern, Western-style state, attempting to coerce Iran into giving up all nuclear enrichment in exchange for precisely nothing from us. And that’s just for starters. No matter how strong you are, you can make your job more difficult if you consistently try to do things that are both very, very hard and not necessarily all that important.

Now consider how the world looks to some other countries. If you were a member of China’s leadership, you’d be deeply fearful of an economic slowdown that might trigger a major challenge to communist party rule. You have border disputes with many of your neighbors (some of them close allies of the mighty United States), and there’s a least some risk that some of them might turn hot. You’re dependent on trade that flows through a variety of maritime choke points. You have more power and more influence than your Maoist predecessors did, but you don’t have any powerful allies and you don’t have an attractive ideological model to offer the rest of the world. From a geopolitical perspective, you’d be thrilled to switch places with the United States, which has no serious rivals, no border disputes with anyone, and still has lots of allies around the world.

And if you were Japanese, Spanish, Iraqi, Iranian, Bahraini, Israeli, Greek, Egyptian, Vietnamese, or Indian, you’d have even more to fret about. So the next time you hear someone bemoaning American "decline," tell them to get a grip and be grateful for the country’s good fortune. And while you’re at it, remind them that most of our foreign policy problems are voluntary: They result from projects we’ve chosen to take on rather than ones that have been forced upon us by necessity. That’s another sign of U.S. power: we have the luxury of choosing how much or how little to do (though it seems to be mostly the former).

In short, Bismarck may have been right when he said God had a "special providence for fools, drunks, and the United States." Which is not to say we can’t make it harder for Him.
