The Interest of America in Sea Power, Present and Future. Alfred Thayer Mahan
general interest to mankind,—to all, at least, of those peoples who, whether directly commercial or not, share in the wide-spreading benefits and inconveniences arising from the fluctuations of trade. But enterprising commercial countries are not content to be mere passive recipients of these diverse influences. By the very characteristics which make them what they are, they are led perforce to desire, and to aim at, control of these decisive regions; for their tenure, like the key of a military position, exerts a vital effect upon the course of trade, and so upon the struggle, not only for bare existence, but for that increase of wealth, of prosperity, and of general consideration, which affect both the happiness and the dignity of nations. Consequently, in every age, according to its particular temperament and circumstances, there will be found manifested this desire for control; sometimes latent in an attitude of simple watchfulness; sometimes starting into vivid action under the impulse of national jealousies, and issuing in diplomatic rivalries or hostile encounter.
Such, accordingly, has been the history of the Central American Isthmus since the time when it became recognized as the natural centre, towards which, if not thwarted by adverse influences, the current of intercourse between East and West inevitably must tend. Here the direction of least resistance was indicated clearly by nature; and a concurrence of circumstances, partly inherent in the general character of the region, partly adventitious or accidental, contributed at an early date, and until very recently, to emphasize and enlarge the importance consequent upon the geographical situation and physical conformation of this narrow barrier between two great seas. For centuries the West India Islands, circling the Caribbean, and guarding the exterior approaches to the Isthmus, continued to be the greatest single source of tropical products which had become increasingly necessary to the civilized nations of Europe. In them, and in that portion of the continent which extended on either side of the Isthmus, known under the vague appellation of the Spanish Main, Great Britain, during her desperate strife with the first Napoleon,—a strife for very existence,—found the chief support of the commercial strength and credit that alone carried her to the triumphant end. The Isthmus and the Caribbean were vital elements in determining the issue of that stern conflict. For centuries, also, the treasures of Mexico and Peru, upon which depended the vigorous action of the great though decadent military kingdom of Spain, flowed towards and accumulated around the Isthmus, where they were reinforced by the tribute of the Philippine Islands, and whence they took their way in the lumbering galleons for the ports of the Peninsula. Where factors of such decisive influence in European politics were at stake, it was inevitable that the rival nations, in peace as well as in open war, should carry their ambitions to the scene; and the unceasing struggle for the mastery would fluctuate with the control of the waters, which, as in all maritime regions, must depend mainly upon naval preponderance, but also in part upon possession of those determining positions, of whose tenure Napoleon said that "war is a business of positions." Among these the Isthmus was chief.
The wild enterprises and bloody cruelties of the early buccaneers were therefore not merely a brutal exhibition of unpitying greed, indicative of the scum of nations as yet barely emerging from barbarism. They were this, doubtless, but they were something more. In the march of events, these early marauders played the same part, in relation to what was to succeed them, as the rude, unscrupulous, lawless adventurers who now precede the ruthless march of civilized man, who swarm over the border, occupy the outposts, and by their excesses stain the fair fame of the race whose pioneers they are. But, while thus libels upon and reproaches to the main body, they nevertheless belong to it, share its essential character, and foretell its inevitable course. Like driftwood swept forward on the crest of a torrent, they betoken the approaching flood. So with the celebrated freebooters of the Spanish Main. Of the same general type,—though varying greatly in individual characteristics, in breadth of view, and even in elevation of purpose,—their piratical careers not only evidenced the local wealth of the scene of their exploits, but attested the commercial and strategic importance of the position upon which in fact that wealth depended. The carcass was there, and the eagles as well as the vultures, the far-sighted as well as the mere carrion birds of prey, were gathering round it. "The spoil of Granada," said one of these mercenary chieftains, two centuries ago, "I count as naught beside the knowledge of the great Lake Nicaragua, and of the route between the Northern and Southern seas which depends upon it."
As time passed, the struggle for the mastery inevitably resulted, by a kind of natural selection, in the growing predominance of the people of the British Islands, in whom commercial enterprise and political instinct were blended so happily. The very lawlessness of the period favored the extension of their power and influence; for it removed from the free play of a nation's innate faculties the fetters which are imposed by our present elaborate framework of precedents, constitutions, and international law. Admirably adapted as these are to the conservation and regular working of a political system, they are, nevertheless, however wise, essentially artificial, and hence are ill adapted to a transition state,—to a period in which order is evolving out of chaos, where the result is durable exactly in proportion to the freedom with which the natural forces are allowed to act, and to reach their own equilibrium without extraneous interference. Nor are such periods confined to the early days of mere lawlessness. They recur whenever a crisis is reached in the career of a nation; when old traditions, accepted maxims, or written constitutions have been outgrown, in whole or in part; when the time has come for a people to recognize that the limits imposed upon its expansion, by the political wisdom of its forefathers, have ceased to be applicable to its own changed conditions and those of the world. The question then raised is not whether the constitution, as written, shall be respected. It is how to reach modifications in the constitution—and that betimes—so that the genius and awakened intelligence of the people may be free to act, without violating that respect for its fundamental law upon which national stability ultimately depends. It is a curious feature of our current journalism that it is clear-sighted and prompt to see the unfortunate trammels in which certain of our religious bodies are held, by the cast-iron tenets imposed upon them by a past generation, while at the same time political tenets, similarly ancient, and imposed with a like ignorance of a future which is our present, are invoked freely to forbid this nation from extending its power and necessary enterprise into and beyond the seas, to which on every side it now has attained.
During the critical centuries when Great Britain was passing through that protracted phase of her history in which, from one of the least among states, she became, through the power of the sea, the very keystone and foundation upon which rested the commercial—for a time even the political—fabric of Europe, the free action of her statesmen and people was clogged by no uneasy sense that the national genius was in conflict with artificial, self-imposed restrictions. She plunged into the brawl of nations that followed the discovery of a new world, of an unoccupied if not unclaimed inheritance, with a vigor and an initiative which gained ever-accelerated momentum and power as the years rolled by. Far and wide, in every sea, through every clime, her seamen and her colonists spread; but while their political genius and traditions enabled them, in regions adapted to the physical well-being of the race, to found self-governing colonies which have developed into one of the greatest, of free states, they did not find, and never have found, that the possession of and rule over barbarous, or semi-civilized, or inert tropical communities, were inconsistent with the maintenance of political liberty in the mother country. The sturdy vigor of the broad principle of freedom in the national life is attested sufficiently by centuries of steady growth, that surest evidence of robust vitality. But, while conforming in the long run to the dictates of natural justice, no feeble scrupulosity impeded the nation's advance to power, by which alone its mission and the law of its being could be fulfilled. No artificial fetters were forged to cramp the action of the state, nor was it drugged with political narcotics to dwarf its growth.
In the region here immediately under consideration, Great Britain entered the contest under conditions of serious disadvantage. The glorious burst of maritime and colonial enterprise which marked the reign of Elizabeth, as the new era dawned when the country recognized the sphere of its true greatness, was confronted by the full power of Spain, as yet outwardly unshaken, in actual tenure of the most important positions in the Caribbean and the Spanish Main, and claiming the right to exclude all others from that quarter of the world. How brilliantly this claim was resisted is well known; yet, had they been then in fashion, there might have been urged, to turn England from the path which has made her what she is, the same arguments that now
