End of the Age of America? Not quite so fast...

China's GDP is a bit less than half that of the U.S by conventional measures.; its population is about four times as large, and its rate of annual GDP growth about triple.  The IMF is now forecasting that China's GDP will surpass that of the U.S. by 2016.

The IMF gets to that watershed so quickly in large part by adjusting current figures for "purchase power parity" (PPP)-- that is, adjusting for the artificially low exchange value of the yuan.  PPP-adjusted, the IMF pegs China's current GDP at about 74% that of the U.S., as opposed to approximately 40% in 2010 as conventionally measured, according to IMF figures.

Brett Arends, reporting this forecast in Marketwatch, concludes:

This is more than a statistical story. It is the end of the Age of America. As a bond strategist in Europe told me two weeks ago, “We are witnessing the end of America’s economic hegemony.”

I wonder if that is necessarily so. Certainly not immediately.  At present, the European Union's economy is larger than that of the U.S., but it projects nowhere near the comparable military or soft power.

While China's population is about  four times that of the U.S., its per capita income, by conventional measures, was a bit less than 1/10 as large in 2010, according to the IMF. Call it 1/6, PPP-adjusted.  China spends 2.2% of GDP on its military, compared to 4.7% in the U.S (Stockholm International Peace Research Institute).  It collects 17% of GDP in taxes, compared to 28% for the U.S (Heritage).

Why the Obama Administration won't cut defense spending

Today's Times has front-page article reporting the first whispers in U.S. government that defense cuts may have to be part of any long-term deficit-reduction plan. The end note brings the assumptions precluding those cuts into into sharp relief.

First, the terms of debate. Defense Secretary Robert Gates, who has long spoken, written and acted on the need to reform Pentagon priorities and procurement practices and eliminate nonessential weapons programs, has called for real growth of 1% per year in the Pentagon budget. Gates does not envision any force reduction, and personnel costs account for two thirds of the Pentagon budget. Some budget planners are beginning to talk about reductions in "end strength" (total personnel) once Obama begins reducing troops in Afghanistan.

Why not? The U.S. significantly reduced military spending during the Clinton years. Outgoing budget director Peter Orzag responds:

“During the end of the cold war, one could imagine a significant downsizing of the American military,” Mr. Orszag said. “That is a fundamentally different proposition than the situation we find ourselves in today.”

Why is our situation "fundamentally different" today?  Gates himself has stressed that we will not face any significant major-power competition in the foreseeable future. He wants the money for the kinds of war we are in -- without apparent end. Here's what he told the Heritage Foundation about major-power competition in May 2008:

Gates the knife?

In today's Financial Times, Clive Crook argues bluntly that Obama's call for "shared sacrifice" means -- must mean -- new taxes. He proposes a 4-point fiscal reform program for the U.S:

Here is what needs to be done, starting in 2011, but to be announced and enacted as soon as possible. First, raise the retirement age. Second, phase out income tax relief on new mortgage loans. Third, introduce a carbon tax. Fourth, introduce a national value added tax, tied to healthcare reform.

Raising the retirement age and and taxing energy consumption are no-brainers. Reducing state support of homeownership violates U.S. taboos but makes sense at least on the margins, e.g. for second homes or for mortgages over a certain amount. A VAT to fund healthcare reform would be, to borrow a pet Obama phrase, a steep hill to climb in political terms, but makes sound fiscal sense.

Crook did not, however, address a spending target that looms as large as social security: defense. Obama stressed throughout the campaign that drawing down the U.S. occupation of Iraq would save an unspecified portion of a $120 billion yearly tab. Even if the withdrawal goes more or less as planned, some of that money will support tens of thousands of remaining troops and some will go to the Afghanistan/Pakistan morass -- where Obama doubtless aims to spend some of his international political capital on obtaining more help from allies.

Most fundamentally, however, Obama will likely take aim at the Pentagon's long-term procurement programs. And in this struggle he will have a no less formidable and savvy ally than Defense Secretary Robert Gates, who has already been working to reign in the Pentagon's deep-rooted penchant to overinvest in a vast array of high-tech hardware designed to win a prospective World War III.

In a series of speeches and writings this year, Gates has outlined the need to shift spending toward counterinsurgency capability -- pilotless drones, well-armored vehicles, more soldiers. These things are not cheap, but they're a lot cheaper than massive procurements of next-gen hardware designed to fight a militarily competitive nation-state. Here's Gates speaking to the Heritage Foundation, on May 13, 2008:

In a world of finite knowledge and limited resources, where we have to make choices and set priorities, it makes sense to lean toward the most likely and lethal scenarios for our military. And it is hard to conceive of any country confronting the United States directly in conventional terms – ship to ship, fighter to fighter, tank to tank – for some time to come.

Two days later, speaking to military contractors, Gates highlighted the Herculean task of turning Pentagon priorities:

A common mantra at Defense is that the rest of the government isn't at war. Well, a lesson I learned fairly early on was that important elements of the Defense Department weren't at war. Preoccupied with future capabilities and procurement programs, wedded to lumbering peacetime process and procedures, stuck in bureaucratic low-gear. The needs of those in combat too often were not addressed urgently or creatively.

More recently, outlining the National Defense Strategy in the current Foreign Affairs, he cast Pentagon budgeting as a problem of risk management:

The most likely catastrophic threats to the U.S. homeland -- for example, that of a U.S. city being poisoned or reduced to rubble by a terrorist attack -- are more likely to emanate from failing states than from aggressor states...It is true that the United States would be hard-pressed to fight a major conventional ground war elsewhere on short notice, but as I have asked before, where on earth would we do that? U.S. air and sea forces have ample untapped striking power should the need arise to deter or punish aggression -- whether on the Korean Peninsula, in the Persian Gulf, or across the Taiwan Strait. So although current strategy knowingly assumes some additional risk in this area, that risk is a prudent and manageable one.

For forty years, it's been politically toxic for a Democrat to make cuts in military spending. Obama doubtless recognizes the need. And Gates gives him essential cover as well as unmatched know-how.

I should add that I don't know whether Gates sees his calls for "balance," risk management and triage as a means to cut defense spending or simply to control its growth. Note, however, that while lamenting 1990s reductions in "national security" capabilities in the Foreign Affairs article, Gates focused not on military spending per se but on the instruments of soft power:

In many ways, the country's national security capabilities are still coping with the consequences of the 1990s, when, with the complicity of both ends of Pennsylvania Avenue, key instruments of U.S. power abroad were reduced or allowed to wither on the bureaucratic vine. The State Department froze the hiring of new Foreign Service officers. The U.S. Agency for International Development dropped from a high of having 15,000 permanent staff members during the Vietnam War to having less than 3,000 today. And then there was the U.S. Information Agency, whose directors once included the likes of Edward R. Murrow. It was split into pieces and folded into a corner of the State Department. Since 9/11, and through the efforts first of Secretary of State Colin Powell and now of Secretary of State Condoleezza Rice, the State Department has made a comeback. Foreign Service officers are being hired again, his and foreign affairs spending has about doubled since President Bush took office.

And while Gates' list of spending priorities is not short, his sense of finite resources is acute:

When it comes to procurement, for the better part of five decades, the trend has gone toward lower numbers as technology gains have made each system more capable. In recent years, these platforms have grown ever more baroque, have become ever more costly, are taking longer to build, and are being fielded in ever-dwindling quantities. Given that resources are not unlimited, the dynamic of exchanging numbers for capability is perhaps reaching a point of diminishing returns. A given ship or aircraft, no matter how capable or well equipped, can be in only one place at one time.

In any case, on the broadest strategic question - whether and how much to cut the Pentagon budget -- Gates is not "the decider." Obama is.
