Sea power is a conscious political choice. A maritime power's world standing depends on keeping taut the sinews of naval might. According to the famed American geostrategist Alfred Thayer Mahan, that means amassing international commerce, forward bases, and merchant and naval shipping. But just as Great Britain, in a "fit of absentmindedness," assembled an empire on which the sun never set, it may be possible to abdicate world leadership thoughtlessly. Indeed, slipping into imperial retrenchment would be easier for the United States, which maintains no colonies abroad, than it was for bygone empires that conquered vast territories and then--having connected national dignity and pride to geographic objects--had to defend them. Withdrawing from diplomatic entanglements and drawing down armed forces are easier than surrendering territory.

That's doubly true since the benefits of policing the global system are remote and abstract, while the benefits of pulling back--cost savings in particular--are concrete and quantifiable. No wonder naval proponents fret about what the future may hold. They fear the United States will back into a decision of enormous importance, letting dollars and cents drive the process rather than strategic thinking. Such fiscal imprudence is not uncommon. As the late admiral J. C. Wylie observes in his treatise, Military Strategy, lawmakers make strategic decisions through the budget process, whether they realize it or not.

Which brings us to Seth Cropsey's new book, Mayday. Cropsey warns that the United States, consciously or not, is allowing a chasm to open between political ends and the ways and means of strategy. Much like Walter Lippmann, who lacerated early twentieth-century presidents for "monstrous imprudence" in foreign policy, Cropsey maintains that--with apologies to Theodore Roosevelt--America still comports itself like a hyperpower while toting smaller and smaller sticks. It has neglected the hard national power needed to back up ambitious policies. Misaligning purpose and power invites challenge and failure. That's especially true in Asia, where a new maritime contender, China, is on the make.

American sea power, says Cropsey, is in a parlous state. He has the chops to make such a case. A senior fellow at the Washington-based Hudson Institute, Cropsey served as deputy under secretary of the navy during the administrations of Ronald Reagan and George H. W. Bush. Thus, he was intimately involved in developing the 1986 maritime strategy, the guiding document for maintaining sea supremacy in the event of war with the Soviet Union. Since then, his career has included stints at the American Enterprise Institute and the Heritage Foundation. Cropsey comments on naval matters regularly in such outlets as the Weekly Standard. He writes fluently about affairs in great waters.

It's difficult to gainsay Cropsey's central message, which is that the U.S. sea services--the navy, Marines and coast guard--are under mounting strain. Arresting this decline, in both numbers and capability, is crucial if Washington wants to sustain the dominant position it inherited after World War II. Failing that, national leaders will have to scale back their policy aims to more modest goals that are executable despite straitened circumstances. There are few other alternatives. Nothing good comes from a mismatch between policy, strategy and means--as Lippmann testified. He blamed the power vacuum created by U.S. ineptitude for encouraging Japanese troublemaking in the 1930s.

Cropsey applies a back-to-basics approach to his topic. He starts with Mahan and his groundbreaking book, The Influence of Sea Power upon History, 1660-1783, which served as a kind of blueprint for the creation of the modern U.S. Navy. A prolific writer and thinker, Mahan also served as the second president of the Naval War College (the institution I call home). Historian Margaret Tuttle Sprout dubbed him America's "evangelist" of sea power, and indeed he beseeched Americans to build up domestic industrial production at home and trade commerce abroad; create fleets of merchantmen and warships; and establish forward bases to support the voyages of fuel-hungry vessels. For him, sea power consisted of this merger of geographic, economic and military implements. Mahan envisioned a symbiotic relationship whereby trade and commerce would generate sufficient tariff revenue to maintain a navy, which in turn would protect commerce. He coined the term "statesmanship directing arms" to denote the art of using naval power for political ends. Sea power thus connotes far more than fleets of armored dreadnoughts battering away at each other on the high seas. It encompasses national purpose, as well as operations and tactics.

Mayday next surveys U.S. maritime history, touching on the classical history that molded the thinking of sea-oriented founders such as John Adams. Oddly, Cropsey spends far more pages reviewing the half-forgotten War of 1812 than he does World War II, a conflict of far greater magnitude and strategic consequence. But he correctly portrays the War of 1812 as a debacle. Mahan and Theodore Roosevelt wrote histories of the war precisely to debunk the popular fantasy that the...
