The only safeguard which the American Union, with all the relative perfection of its laws, possesses against the dissolution which would be produced by a great war, lies in its probable exemption from that calamity. Placed in the centre of an immense continent, which offers a boundless field for human industry, the Union is almost as much insulated from the world as if its frontiers were girt by the ocean. Canada contains only a million of inhabitants, and its population is divided into two inimical nations. The rigor of the climate limits the extension of its territory, and shuts up its ports during the six months of winter. From Canada to the Gulf of Mexico a few savage tribes are to be met with, which retire, perishing in their retreat, before six thousand soldiers. To the South, the Union has a point of contact with the empire of Mexico; and it is thence that serious hostilities may one day be expected to arise. But for a long while to come the uncivilized state of the Mexican community, the depravity of its morals, and its extreme poverty, will prevent that country from ranking high amongst nations. *w As for the Powers of Europe, they are too distant to be formidable. w [ [War broke out between the United States and Mexico in 1846, and ended in the conquest of an immense territory, including California.]] The great advantage of the United States does not, then, consist in a Federal Constitution which allows them to carry on great wars, but in a geographical position which renders such enterprises extremely improbable. No one can be more inclined than I am myself to appreciate the advantages of the federal system, which I hold to be one of the combinations most favorable to the prosperity and freedom of man. I envy the lot of those nations which have been enabled to adopt it; but I cannot believe that any confederate peoples could maintain a long or an equal contest with a nation of similar strength in which the government should be centralized. A people which should divide its sovereignty into fractional powers, in the presence of the great military monarchies of Europe, would, in my opinion, by that very act, abdicate its power, and perhaps its existence and its name. But such is the admirable position of the New World that man has no other enemy than himself; and that, in order to be happy and to be free, it suffices to seek the gifts of prosperity and the knowledge of freedom.
