The fatal arithmetic of imperial decline

An Empire at Risk

Excerpts:

... if the United States succumbs to a fiscal crisis, as an increasing number of economic experts fear it may, then the entire balance of global economic power could shift. Military experts talk as if the president's decision about whether to send an additional 40,000 troops to Afghanistan is a make-or-break moment. In reality, his indecision about the deficit could matter much more for the country's long-term national security. Call the United States what you like—superpower, hegemon, or empire—but its ability to manage its finances is closely tied to its ability to remain the predominant global military power.

...

... there is no end in sight to the borrowing binge. Unless entitlements are cut or taxes are raised, there will never be another balanced budget. Let's assume I live another 30 years and follow my grandfathers to the grave at about 75. By 2039, when I shuffle off this mortal coil, the federal debt held by the public will have reached 91 percent of GDP, according to the CBO's extended baseline projections.

...

[Paul Krugman] "My prediction is that politicians will eventually be tempted to resolve the [fiscal] crisis the way irresponsible governments usually do: by printing money, both to pay current bills and to inflate away debt. And as that temptation becomes obvious, interest rates will soar."

...

... the federal government's interest payments are forecast by the CBO to rise from 8 percent of revenues in 2009 to 17 percent by 2019, even if rates stay low and growth resumes. If rates rise even slightly and the economy flatlines, we'll get to 20 percent much sooner. And history suggests that once you are spending as much as a fifth of your revenues on debt service, you have a problem. It's all too easy to find yourself in a vicious circle of diminishing credibility. The investors don't believe you can afford your debts, so they charge higher interest, which makes your position even worse.

This matters more for a superpower than for a small Atlantic island for one very simple reason. As interest payments eat into the budget, something has to give—and that something is nearly always defense expenditure. According to the CBO, a significant decline in the relative share of national security in the federal budget is already baked into the cake. On the Pentagon's present plan, defense spending is set to fall from above 4 percent now to 3.2 percent of GDP in 2015 and to 2.6 percent of GDP by 2028.

...

This is how empires decline. It begins with a debt explosion. It ends with an inexorable reduction in the resources available for the Army, Navy, and Air Force. Which is why voters are right to worry about America's debt crisis. According to a recent Rasmussen report, 42 percent of Americans now say that cutting the deficit in half by the end of the president's first term should be the administration's most important task—significantly more than the 24 percent who see health-care reform as the No. 1 priority. But cutting the deficit in half is simply not enough. If the United States doesn't come up soon with a credible plan to restore the federal budget to balance over the next five to 10 years, the danger is very real that a debt crisis could lead to a major weakening of American power.
