"We've Heard All This About American Decline Before." This time it's different

It's certainly true that America has been through cycles of declinism in the past. Campaigning for the presidency in 1960, John F. Kennedy complained, "American strength relative to that of the Soviet Union has been slipping, and communism has been advancing steadily in every area of the world." Ezra Vogel's Japan as Number One was published in 1979, heralding a decade of steadily rising paranoia about Japanese manufacturing techniques and trade policies.
In the end, of course, the Soviet and Japanese threats to American supremacy proved chimerical. So Americans can be forgiven if they greet talk of a new challenge from China as just another case of the boy who cried wolf. But a frequently overlooked fact about that fable is that the boy was eventually proved right. The wolf did arrive -- and China is the wolf.

The Chinese challenge to the United States is more serious for both economic and demographic reasons. The Soviet Union collapsed because its economic system was highly inefficient, a fatal flaw that was disguised for a long time because the USSR never attempted to compete on world markets. China, by contrast, has proved its economic prowess on the global stage. Its economy has been growing at 9 to 10 percent a year, on average, for roughly three decades. It is now the world's leading exporter and its biggest manufacturer, and it is sitting on more than $2.5 trillion of foreign reserves. Chinese goods compete all over the world. This is no Soviet-style economic basket case.

Japan, of course, also experienced many years of rapid economic growth and is still an export powerhouse. But it was never a plausible candidate to be No. 1. The Japanese population is less than half that of the United States, which means that the average Japanese person would have to be more than twice as rich as the average American before Japan's economy surpassed America's. That was never going to happen. By contrast, China's population is more than four times that of the United States. The famous projection by Goldman Sachs that China's economy will be bigger than that of the United States by 2027 was made before the 2008 economic crash. At the current pace, China could be No. 1 well before then.

China's economic prowess is already allowing Beijing to challenge American influence all over the world. The Chinese are the preferred partners of many African governments and the biggest trading partner of other emerging powers, such as Brazil and South Africa. China is also stepping in to buy the bonds of financially strapped members of the eurozone, such as Greece and Portugal.

And China is only the largest part of a bigger story about the rise of new economic and political players. America's traditional allies in Europe -- Britain, France, Italy, even Germany -- are slipping down the economic ranks. New powers are on the rise: India, Brazil, Turkey. They each have their own foreign-policy preferences, which collectively constrain America's ability to shape the world. Think of how India and Brazil sided with China at the global climate-change talks. Or the votes by Turkey and Brazil against America at the United Nations on sanctions against Iran. That is just a taste of things to come.
