The Interest of America in Sea Power, Present and Future. Alfred Thayer Mahan
The United States is by far the greatest, in numbers, interests, and power, of the communities bordering upon the eastern shores of the North Pacific; and the relations of the Hawaiian Islands to her naturally would be, and actually are, more numerous and more important than they can be to any other state. This is true, although, unfortunately for the equally natural wishes of Great Britain and her colonies, the direct routes from British Columbia to Eastern Australia and New Zealand, which depend upon no building of a future canal, pass as near the islands as those already mentioned. Such a fact, that this additional great highway runs close to the group, both augments and emphasizes their strategic importance; but it does not affect the statement just made, that the interest of the United States in them surpasses that of Great Britain, and dependent upon a natural cause, nearness, which has been admitted always as a reasonable ground for national self-assertion. It is unfortunate, doubtless, for the wishes of British Columbia, and for the communications, commercial and military, depending upon the Canadian Pacific Railway, that the United States lies between them and the South Pacific, and is the state nearest to Hawaii; but, the fact being so, the interests of our sixty-five million people, in a position so vital to our part in the Pacific, must be allowed to outweigh those of the six millions of Canada.
From the foregoing considerations may be inferred the importance of the Hawaiian Islands as a position powerfully influencing the commercial and military control of the Pacific, and especially of the Northern Pacific, in which the United States, geographically, has the strongest right to assert herself. These are the main advantages, which can be termed positive: those, namely, which directly advance commercial security and naval control. To the negative advantages of possession, by removing conditions which, if the islands were in the hands of any other power, would constitute to us disadvantages and threats, allusion only will be made. The serious menace to our Pacific coast and our Pacific trade, if so important a position were held by a possible enemy, has been mentioned frequently in the press, and dwelt upon in the diplomatic papers which from time to time are given to the public. It may be assumed that it is generally acknowledged. Upon one particular, however, too much stress cannot be laid, one to which naval officers cannot but be more sensitive than the general public, and that is the immense disadvantage to us of any maritime enemy having a coaling-station well within twenty-five hundred miles, as this is, of every point of our coast-line from Puget Sound to Mexico. Were there many others available, we might find it difficult to exclude from all. There is, however, but the one. Shut out from the Sandwich Islands as a coal base, an enemy is thrown back for supplies of fuel to distances of thirty-five hundred or four thousand miles,—or between seven thousand and eight thousand, going and coming,—an impediment to sustained maritime operations well-nigh prohibitive. The coal-mines of British Columbia constitute, of course, a qualification to this statement; but upon them, if need arose, we might hope at least to impose some trammels by action from the land side. It is rarely that so important a factor in the attack or defence of a coast-line—of a sea frontier—is concentrated in a single position; and the circumstance renders doubly imperative upon us to secure it, if we righteously can.
It is to be hoped, also, that the opportunity thus thrust upon us may not be viewed narrowly, as though it concerned but one section of our country or one portion of its external trade or influence. This is no mere question of a particular act, for which, possibly, just occasion may not have offered yet; but of a principle, a policy, fruitful of many future acts, to enter upon which, in the fulness of our national progress, the time now has arrived. The principle being accepted, to be conditioned only by a just and candid regard for the rights and reasonable susceptibilities of other nations,—none of which is contravened by the step here immediately under discussion,—the annexation, even, of Hawaii would be no mere sporadic effort, irrational because disconnected from an adequate motive, but a first-fruit and a token that the nation in its evolution has aroused itself to the necessity of carrying its life—that has been the happiness of those under its influence—beyond the borders which heretofore have sufficed for its activities. That the vaunted blessings of our economy are not to be forced upon the unwilling may be conceded; but the concession does not deny the right nor the wisdom of gathering in those who wish to come. Comparative religion teaches that creeds which reject missionary enterprise are foredoomed to decay. May it not be so with nations? Certainly the glorious record of England is consequent mainly upon the spirit, and traceable to the time, when she launched out into the deep—without formulated policy, it is true, or foreseeing the future to which her star was leading, but obeying the instinct which in the infancy of nations anticipates the more reasoned impulses of experience. Let us, too, learn from her experience. Not all at once did England become the great sea power which she is, but step by step, as opportunity offered, she has moved on to the world-wide pre-eminence now held by English speech, and by institutions sprung from English germs. How much poorer would the world have been, had Englishmen heeded the cautious hesitancy that now bids us reject every advance beyond our shore-lines! And can any one doubt that a cordial, if unformulated, understanding between the two chief states of English tradition, to spread freely, without mutual jealousy and in mutual support, would increase greatly the world's sum of happiness?
But if a plea of the world's welfare seem suspiciously like a cloak for national self-interest, let the latter be accepted frankly as the adequate motive which it assuredly is. Let us not shrink from pitting a broad self-interest against the narrow self-interest to which some would restrict us. The demands of our three great seaboards, the Atlantic, the Gulf, and the Pacific,—each for itself, and all for the strength that comes from drawing closer the ties between them,—are calling for the extension, through the Isthmian Canal, of that broad sea common along which, and along which alone, in all the ages prosperity has moved. Land carriage, always restricted and therefore always slow, toils enviously but hopelessly behind, vainly seeking to replace and supplant the royal highway of nature's own making. Corporate interests, vigorous in that power of concentration which is the strength of armies and of minorities, may here withstand for a while the ill-organized strivings of the multitude, only dimly conscious of its wants; yet the latter, however temporarily opposed and baffled, is sure at last, like the blind forces of nature, to overwhelm all that stand in the way of its necessary progress. So the Isthmian Canal is an inevitable part in the future of the United States; yet one that cannot be separated from other necessary incidents of a policy dependent upon it, whose details cannot be foreseen exactly. But because the precise steps that hereafter may be opportune or necessary cannot yet be foretold certainly, is not a reason the less, but a reason the more, for establishing a principle of action which may serve to guide as opportunities arise. Let us start from the fundamental truth, warranted by history, that the control of the seas, and especially along the great lines drawn by national interest or national commerce, is the chief among the merely material elements in the power and prosperity of nations. It is so because the sea is the world's great medium of circulation. From this necessarily follows the principle that, as subsidiary to such control, it is imperative to take possession, when it can be done righteously, of such maritime positions as contribute to secure command. If this principle be adopted, there will be no hesitation about taking the positions—and they are many—upon the approaches to the Isthmus, whose interests incline them to seek us. It has its application also to the present case of Hawaii.
There is, however, one caution to be given from the military point of view, beyond the need of which the world has not yet passed. Military positions, fortified posts, by land or by sea, however strong or admirably situated, do not confer control by themselves alone. People often say that such an island or harbor will give control of such a body of water. It is an utter, deplorable, ruinous mistake. The phrase indeed may be used by some only loosely, without forgetting other implied conditions of adequate protection and adequate navies; but the confidence of our own nation in its native strength, and its indifference to the defence of its ports and the sufficiency of its fleet, give reason to fear that the full consequences of a forward step may not be weighed soberly. Napoleon, who knew better, once talked this way. "The islands of San Pietro, Corfu, and Malta," he wrote, "will make us masters of the whole Mediterranean." Vain boast! Within one year Corfu, in two years Malta, were rent away from the state that could not support them by its ships. Nay, more: had Bonaparte not taken the latter stronghold out of the hands of its degenerate but innocuous government, that citadel of the Mediterranean would perhaps—would probably—never have passed into those of his chief enemy. There is here also a lesson for us.
