In an article for the March/April issue of Foreign Affairs, "Complexity and Collapse: Empires on the Edge of Chaos," due out later this week, author and historian Niall Ferguson posits that the life cycles of great powers might not follow the long-accepted pattern of gradual rise and fall. Rather, he says, "it is possible that this whole conceptual framework is, in fact, flawed," and that empires fall quickly and without warning. With that in mind, Ferguson explores what it might mean for the geopolitical status quo.
If empires are complex systems that sooner or later succumb to sudden and catastrophic malfunctions, rather than cycling sedately from Arcadia to Apogee to Armageddon, what are the implications for the United States today? First, debating the stages of decline may be a waste of time—it is a precipitous and unexpected fall that should most concern policymakers and citizens. Second, most imperial falls are associated with fiscal crises. All the above cases were marked by sharp imbalances between revenues and expenditures, as well as difficulties with financing public debt. Alarm bells should therefore be ringing very loudly, indeed, as the United States contemplates a deficit for 2009 of more than $1.4 trillion—about 11.2 percent of gdp, the biggest deficit in 60 years—and another for 2010 that will not be much smaller. Public debt, meanwhile, is set to more than double in the coming decade, from $5.8 trillion in 2008 to $14.3 trillion in 2019. Within the same timeframe, interest payments on that debt are forecast to leap from eight percent of federal revenues to 17 percent.
These numbers are bad, but in the realm of political entities, the role of perception is just as crucial, if not more so. In imperial crises, it is not the material underpinnings of power that really matter but expectations about future power. The fiscal numbers cited above cannot erode U.S. strength on their own, but they can work to weaken a long-assumed faith in the United States’ ability to weather any crisis. For now, the world still expects the United States to muddle through, eventually confronting its problems when, as Churchill famously said, all the alternatives have been exhausted. Through this lens, past alarms about the deficit seem overblown, and 2080—when the U.S. debt may reach staggering proportions—seems a long way oª, leaving plenty of time to plug the fiscal hole. But one day, a seemingly random piece of bad news— perhaps a negative report by a rating agency—will make the headlines during an otherwise quiet news cycle. Suddenly, it will be not just a few policy wonks who worry about the sustainability of U.S. fiscal policy but also the public at large, not to mention investors abroad. It is this shift that is crucial: a complex adaptive system is in big trouble when its component parts lose faith in its viability.
