Though Americans fear a decline in the country's global influence, Stephen M. Walt argues that this may be an unnecessary fear.
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.
