Speaking Truth to a Superpower

Bacevich describes the military crisis with an insider's authority. He dissects an American military doctrine that wildly overstates the utility of armed force in politically delicate situations. He decries the mediocrity of America's four-star generals, with particular scorn for Gen. Tommy Franks, original commander of the wars in Afghanistan and Iraq. He calls the all-volunteer Army, isolated from the society it is supposed to protect, "an imperial constabulary" that "has become an extension of the imperial presidency."

The heart of the matter, Bacevich argues, is that war can never be considered a useful political tool, because wars invariably produce unintended consequences: "War's essential nature is fixed, permanent, intractable, and irrepressible. War's constant companions are uncertainty and risk." New inventions cannot alter these facts, Bacevich writes. "Any notion that innovative techniques and new technologies will subject war to definitive human direction is simply whimsical," he writes, quoting Churchill approvingly: "The statesman who yields to war fever is no longer the master of policy, but the slave of unforeseeable and uncontrollable events."

Yet the United States is today engaged in multiple wars that both exceed the capacity of the all-volunteer force and are highly unlikely to achieve their political aims, Bacevich argues. War is not the answer to the challenges we face, he says, and "to persist in following that path is to invite inevitable overextension, bankruptcy and ruin."

The Limits of Power is a dense book but gracefully written and easy to read. It is chockablock with provocative ideas and stern judgments. Bacevich's brand of intellectual assuredness is rare in today's public debates. Many of our talking heads and commentators are cocksure, of course, but few combine confidence with knowledge and deep thought the way Bacevich does here.

Some of Bacevich's asides, however, are highly debatable -- that Richard M. Nixon and Mao Tse-tung together helped bring down the Soviet empire, for example. Bacevich is no globalist, and he treats trade as a sign of national weakness. One could provide a long list of objections of this kind, but quibbles cannot undermine Bacevich's big argument, which is elegant and powerful.

The end of the Cold War left the United States feeling omnipotent but without a utilitarian doctrine to guide its foreign policy. Instead, we have succumbed, again and again, to the military temptation. In Iraq we stumbled into a real disaster. If we cannot get our goals and our means into balance soon, our future will be a lot less fun than our past.

Bacevich is argumentative, and his case is not proven beyond a reasonable doubt, but at the end of this book, a serious reader has a difficult choice: to embrace Bacevich's general view or to construct a genuinely persuasive alternative. For many years our leaders have failed to do either. The price of their failure has been high and could go much higher. Bacevich knows a lot about the costs himself; his only son, Andrew John Bacevich, a first lieutenant in the Army, was killed in Iraq last year.

Candidates for office owe the voters their take on the big argument here: Do they think military power remains a tool of choice to help the United States make its way through the perils of the modern world? If so, can they explain why? ·
