To look for a continuation of harmony between a number of independent, unconnected sovereignties in the same… — Alexander Hamilton

When the sword is once drawn, the passions of men observe no bounds of moderation. The suggestions of wounded pride, the instigations of irritated resentment, would be apt to carry the States against which the arms of the Union were exerted, to any extremes necessary to avenge the affront or to avoid the disgrace of submission. The first war of this kind would probably terminate in a dissolution of the Union.

A tolerable expertness in military movements is a business that requires time and practice. It is not a day, or even a week, that will suffice for the attainment of it. To oblige the great body of the yeomanry, and of the other classes of the citizens, to be under arms for the purpose of going through military exercises and evolutions, as often as might be necessary to acquire the degree of perfection which would entitle them to the character of a well-regulated militia, would be a real grievance to the people, and a serious public inconvenience and loss. It would form an annual deduction from the productive labor of the country, to an amount which, calculating upon the present numbers of the people, would not fall far short of the whole expense of the civil establishments of all the States. To attempt a thing which would abridge the mass of labor and industry to so considerable an extent, would be unwise: and the experiment, if made, could not succeed, because it would not long be endured. Little more can reasonably be aimed at, with respect to the people at large, than to have them properly armed and equipped; and in order to see that this be not neglected, it will be necessary to assemble them once or twice in the course of a year.

Let us recollect that peace or war will not always be left to our option; that however moderate or unambitious we may be, we cannot count upon the moderation, or hope to extinguish the ambition of others.
