It is perfectly reasonable and legitimate, in estimating our needs of military preparation, to take into account the remoteness of the chief naval and military nations from our shores, and the consequent difficulty of maintaining operations at such a distance. It is equally proper, in framing our policy, to consider the jealousies of the European family of states, and their consequent unwillingness to incur the enmity of a people so strong as ourselves; their dread of our revenge in the future, as well as their inability to detach more than a certain part of their forces to our shores without losing much of their own weight in the councils of Europe. In truth, a careful determination of the force that Great Britain or France could probably spare for operations against our coasts, if the latter were suitably defended, without weakening their European position or unduly exposing their colonies and commerce, is the starting-point from which to calculate the strength of our own navy. If the latter be superior to the force that thus can be sent against it, and the coast be so defended as to leave the navy free to strike where it will, we can maintain our rights; not merely the rights which international law concedes, and which the moral sense of nations now supports, but also those equally real rights which, though not conferred by law, depend upon a clear preponderance of interest, upon obviously necessary policy, upon self-preservation, either total or partial. Were we so situated now in respect of military strength, we could secure our perfectly just claim as to the seal fisheries; not by seizing foreign ships on the open sea, but by the evident fact that, our cities being protected from maritime attack, our position and superior population lay open the Canadian Pacific, as well as the frontier of the Dominion, to do with as we please. Diplomats do not flourish such disagreeable truths in each other's faces; they look for a modus vivendi , and find it.
While, therefore, the advantages of our own position in the western hemisphere, and the disadvantages under which the operations of a European state would labor, are undeniable and just elements in the calculations of the statesman, it is folly to look upon them as sufficient alone for our security. Much more needs to be cast into the scale that it may incline in favor of our strength. They are mere defensive factors, and partial at that. Though distant, our shores can be reached; being defenceless, they can detain but a short time a force sent against them. With a probability of three months' peace in Europe, no maritime power would fear to support its demands by a number of ships with which it would be loath indeed to part for a year.
Yet, were our sea frontier as strong as it now is weak, passive self-defence, whether in trade or war, would be but a poor policy, so long as this world continues to be one of struggle and vicissitude. All around us now is strife; "the struggle of life," "the race of life," are phrases so familiar that we do not feel their significance till we stop to think about them. Everywhere nation is arrayed against nation; our own no less than others. What is our protective system but an organized warfare? In carrying it on, it is true, we have only to use certain procedures which all states now concede to be a legal exercise of the national power, even though injurious to themselves. It is lawful, they say, to do what we will with our own. Are our people, however, so unaggressive that they are likely not to want their own way in matters where their interests turn on points of disputed right, or so little sensitive as to submit quietly to encroachment by others, in quarters where they long have considered their own influence should prevail?
Our self-imposed isolation in the matter of markets, and the decline of our shipping interest in the last thirty years, have coincided singularly with an actual remoteness of this continent from the life of the rest of the world. The writer has before him a map of the North and South Atlantic oceans, showing the direction of the principal trade routes and the proportion of tonnage passing over each; and it is curious to note what deserted regions, comparatively, are the Gulf of Mexico, the Caribbean Sea, and the adjoining countries and islands. A broad band stretches from our northern Atlantic coast to the English Channel; another as broad from the British Islands to the East, through the Mediterranean and Red Sea, overflowing the borders of the latter in order to express the volume of trade. Around either cape—Good Hope and Horn—pass strips of about one-fourth this width, joining near the equator, midway between Africa and South America. From the West Indies issues a thread, indicating the present commerce of Great Britain with a region which once, in the Napoleonic wars, embraced one-fourth of the whole trade of the Empire. The significance is unmistakable: Europe has now little mercantile interest in the Caribbean Sea.
When the Isthmus is pierced, this isolation will pass away, and with it the indifference of foreign nations. From wheresoever they come and whithersoever they afterward go, all ships that use the canal will pass through the Caribbean. Whatever the effect produced upon the prosperity of the adjacent continent and islands by the thousand wants attendant upon maritime activity, around such a focus of trade will centre large commercial and political interests. To protect and develop its own, each nation will seek points of support and means of influence in a quarter where the United States always has been jealously sensitive to the intrusion of European powers. The precise value of the Monroe doctrine is understood very loosely by most Americans, but the effect of the familiar phrase has been to develop a national sensitiveness, which is a more frequent cause of war than material interests; and over disputes caused by such feelings there will preside none of the calming influence due to the moral authority of international law, with its recognized principles, for the points in dispute will be of policy, of interest, not of conceded right. Already France and Great Britain are giving to ports held by them a degree of artificial strength uncalled for by their present importance. They look to the near future. Among the islands and on the mainland there are many positions of great importance, held now by weak or unstable states. Is the United States willing to see them sold to a powerful rival? But what right will she invoke against the transfer? She can allege but one—that of her reasonable policy supported by her might.
Whether they will or no, Americans must now begin to look outward. The growing production of the country demands it. An increasing volume of public sentiment demands it. The position of the United States, between the two Old Worlds and the two great oceans, makes the same claim, which will soon be strengthened by the creation of the new link joining the Atlantic and Pacific. The tendency will be maintained and increased by the growth of the European colonies in the Pacific, by the advancing civilization of Japan, and by the rapid peopling of our Pacific States with men who have all the aggressive spirit of the advanced line of national progress. Nowhere does a vigorous foreign policy find more favor than among the people west of the Rocky Mountains.
It has been said that, in our present
