Overheated topics invariably produce ill-considered books. Some people will remember the time, in the late nineteen-eighties, when Japan was about to buy up America and conquer the world. Many a tidy sum was made on that premise. These days, the possibility of war with China is stirring emotions and keeping publishers busy. A glance at a few new books suggests what scholars and journalists are thinking about the prospect of an Asian conflagration; the quality of their reflections is, to say the least, variable.

The worst of the bunch, Graham Allison’s “Destined for War” (Houghton Mifflin Harcourt), may also be the most influential, given that its thesis rests on a catchphrase Allison has popularized, “Thucydides’s Trap.” Even China’s President, Xi Jinping, is fond of quoting it. “On the current trajectory,” Allison contends, “war between the U.S. and China in the decades ahead is not just possible, but much more likely than currently recognized.” The reason, he says, can be traced to the problem described in the fifth century B.C.E. in Thucydides’ account of the Peloponnesian War. Sparta, as the established power, felt threatened by the rising might of Athens. In such conditions, Allison writes, “not just extraordinary, unexpected events, but even ordinary flashpoints of foreign affairs, can trigger large-scale conflict.”

Allison sees Thucydides’ Trap in the wars between a rising England and the established Dutch Republic in the seventeenth century, a rising Germany versus Britain in the early twentieth century, and a rising Japan versus the United States in the nineteen-forties. Some historical tensions between rising powers and ruling ones were resolved without a catastrophic war (the Soviet challenge to U.S. dominance), but many, Allison warns, were not. And there’s no disputing China’s steep military and economic rise in recent decades. Its annual military budget has, for most of the past decade, increased by double digits, and the People’s Liberation Army, even in its newly streamlined form, has nearly a million more active service members than the United States has. As recently as 2004, China’s economy was less than half that of the United States. Today, in terms of purchasing-power parity, China has left the United States behind. Allison is so excited by China’s swift growth that his prose often sounds like a mixture of a Thomas Friedman column and a Maoist propaganda magazine like China Reconstructs. Rome wasn’t built in a day? Well, he writes, someone “clearly forgot to tell the Chinese. By 2005, the country was building the square-foot equivalent of today’s Rome every two weeks.”

Allison underrates the many problems that could slow things down quite soon: China’s population is aging so rapidly that an ever smaller pool of young people will have to support a growing number of old people, who lack proper welfare provisions; the country is an ecological disaster zone; the dead hand of Communist Party control makes necessary economic reforms difficult; innovative thinking is hampered by censorship; and so on. In terms of military hardware—aircraft carriers and the like—China still lags well behind the United States. And the United States has a wide network of allies in Asia, while China has almost none. Still, China plainly aspires to be the dominant power in East and Southeast Asia, and this is making the United States and its allies increasingly nervous. Southeast Asians are spooked by Chinese claims of sovereignty over the South China Sea, bolstered by the construction of artificial islands with landing grounds. Japan, although it has a substantial military force, is saddled with a pacifist constitution. South Korea doesn’t quite know whether to resist Chinese domination or cozy up to it. The British historian Michael Howard’s remark about nineteenth-century France, quoted in Allison’s book, could easily apply to the United States today. The “most dangerous of all moods,” Howard said, is “that of a great power which sees itself declining to the second rank.”

Allison finds risks of Thucydides’ Trap on both sides of the divide: the rising power feels frustrated and the established one feels threatened. The thesis, in those general terms, isn’t implausible. His book would be more persuasive, however, if he knew more about China. Allison’s only informants on the subject appear to be Henry Kissinger and the late Singaporean Prime Minister Lee Kuan Yew, both of whom he regards with awe. This leads to some odd contradictions and a number of serious historical howlers. On one page, quoting Kissinger quoting the ancient military strategist Sun Tzu, Allison assures us that China likes to outclass its enemies without using force. On a later page, he warns us that Chinese leaders may use military force “preemptively to surprise a stronger opponent who would not have done likewise.” ...
