Over at National Journal's National Security Experts blog, this week's question revolves around the health of the U.S. economy, and its relationship to U.S. power.
The editors ask:
How serious a threat is the mounting debt to the nation's standing as the world's only superpower? Can the U.S. continue to spend more than all other countries combined on its military forces given burdensome debt levels? In what other ways does the mounting debt undermine the country's strategic position? [...]
My response:
Our long-term fiscal imbalance, which increasingly amounts to a massive intergenerational wealth transfer, is clearly a sign of our decline. But it is a decline that has been a long time coming. (I first wrote about the insolvency of the Social Security system as a college sophomore, 23 years ago.) As such, it is tempting for people to assume that we'll figure our way out of this mess before a complete collapse. Let's call them, at the risk of a double negative, the declinist naysayers. And, even if they are willing to admit to the problem in the abstract, the naysayers can point to the more serious, and urgent, imbalances between pensioners and those who pay the pensions in Europe or Japan and say "At least we aren't them."
That is a pretty shoddy argument, but it seems to be ruling the day. We can talk about the obvious unsustainability of using taxes on current workers to pay benefits for retirees until we're blue in the face. And my second grader can do the math on a system that was designed when workers outnumbered beneficiaries by 16.5 to 1, and in which, by 2030, that ratio will fall to 2 to 1. It simply doesn't add up. (For more on this, much more, see my colleague Jagadeesh Gokhale's latest.)
But this isn't a math problem; this is a political problem. The incentive to kick the can down the road is overwhelming. The pain in attempting to deal with the problem in the here and now is, well, painful. It is hardly surprising, therefore, that members of Congress / Parliament / Bundestag / Diet, etc, have become very good at avoiding the issue altogether. And many of those who have chosen to tackle it are "spending more time with their families."
What does all this mean for the United States's standing as the world superpower? Less than you might think. Our difficulties in two medium-sized countries in SW/Central Asia have done more to puncture the illusion of American power than our political inability to deal with domestic problems. Our fiscal insolvency might convince other countries to play a larger role, if they genuinely feared for their safety. But other countries, especially our allies, are cutting military spending, while Uncle Sam continues to bear the weight of the world on his shoulders. In other words, our ability to maintain our global superpower status isn't driven by our economic problems. But it is strategically stupid.
It is here that I take issue with Ron Marks's contention that we spend less today than during the Cold War. While technically accurate, measuring military spending as a share of GDP is utterly misleading (as I've argued elsewhere.) If the point is to argue that we could spend more, I agree. But the measure doesn't address whether we should do so.
We should think of military spending not as a share of the American economy, but rather relative to the threats we face. In real terms (constant current dollars), we spend today more than when we were facing down a nuclear-armed adversary with a massive army stationed in Eastern Europe and a navy that plied the seven seas from Cam Ranh Bay to Cuba. We spend more than during the height of the Vietnam or Korean Wars. Today, terrorist leaders are hunkered down in safe houses somewhere in, well, somewhere. In other words, what we spend is utterly disconnected from the threats we face, a point that is easily obscured when one focuses on military spending as a share of total output.
We spend so much today not because we are facing down one very scary adversary, but because we are facing down dozens or hundreds of small adversaries that should be confronted by others. After the Cold War ended, our strategy expanded to justify a massive military. Since 9/11, it has expanded further. Our fiscal crisis alone won't force a reevaluation of our grand strategy. It will take sound strategic judgement, and a bit of political courage, to turn things around.
In the cover letter to his just-released National Security Strategy, President Obama acknowledged that it doesn't make sense for any one country to attempt to police the entire planet, irrespective of the costs. Unfortunately, the document fails to outline a mechanism for transferring some of the burdens of global governance to others who benefit from a peaceful and prosperous world order. We should assume, therefore, that the U.S. military will continue to be the go-to force for cleaning up all manner of problems, and that the U.S. taxpayers will be stuck with the bill.
