The cynical view of warnings about a mounting Chinese threat is that they are largely Pentagon budget-building ploys: if the U.S. military is “only” going to fight insurgents and terrorists in the future, it doesn’t really need the next generation of expensive fighter planes or attack submarines. Powerful evidence for this view—apart from familiarity with Pentagon budget debates over the years—is that many of the neoconservative thinkers who since 9/11 have concentrated on threats from Iraq, Afghanistan, and Iran were before that time writing worriedly about China. The most powerful counterargument is that China’s rise is so consequential and unprecedented in scale that it would be naive not to expect military ramifications. My instincts lie with the skeptical camp: as I’ve often written through the past three years, China has many more problems than most Americans can imagine, and its power is much less impressive up close. But on my return to America, I asked a variety of military, governmental, business, and academic officials about how the situation looks from their perspective. In most ways, their judgment was reassuringly soothing; unfortunately, it left me with a new problem to worry about.

Without meaning to sound flip, I think the strictly military aspects of U.S.-China relations appear to be something Americans can rest easy about for a long time to come. Hypercautious warnings to the contrary keep cropping up, especially in the annual reports on China’s strategic power produced since 2000 by the Pentagon each spring and by the U.S.-China Economic and Security Review Commission each fall. Yet when examined in detail, even these show the limits of the Chinese threat. To summarize:

• In overall spending, the United States puts between five and 10 times as much money into the military per year as China does, depending on different estimates of China’s budget. Spending does not equal effectiveness, but it suggests the difference in scale.

• In sophistication of equipment, Chinese forces are only now beginning to be brought up to speed. For instance, just one-quarter of its naval surface fleet is considered “modern” in electronics, engines, and weaponry.

• In certain categories of weaponry, the Chinese don’t even compete. For instance, the U.S. Navy has 11 nuclear-powered aircraft-carrier battle groups. The Chinese navy is only now moving toward construction of its very first carrier.

• In the unglamorous but crucial components of military effectiveness—logistics, training, readiness, evolving doctrine—the difference between Chinese and American standards is not a gap but a chasm. After a natural disaster anywhere in the world, the American military’s vast airlift and sealift capacity often brings rescue supplies. The Chinese military took days to reach survivors after the devastating Sichuan earthquake in May of 2008, because it has so few helicopters and emergency vehicles.
