Among the acknowledged rights of nations is that which each possesses of establishing that form of government which it may deem most conducive to the happiness and prosperity of its own citizens, of changing that form as circumstances may require, and of managing its internal affairs according to its own will. The people of the United States claim this right for themselves, and they readily concede it to others. Hence it becomes an imperative duty not to interfere in the government or internal policy of other nations; and although we may sympathize with the unfortunate or the oppressed everywhere in their struggles for freedom, our principles forbid us from taking any part in such foreign contests. We make no wars to promote or to prevent successions to thrones, to maintain any theory of a balance of power, or to suppress the actual government which any country chooses to establish for itself. We instigate no revolutions, nor suffer any hostile military expeditions to be fitted out in the United States to invade the territory or provinces of a friendly nation. The great law of morality ought to have a national as well as a personal and individual application. We should act toward other nations as we wish them to act toward us, and justice and conscience should form the rule of conduct between governments, instead of mere power, self interest, or the desire of aggrandizement. To maintain a strict neutrality in foreign wars, to cultivate friendly relations, to reciprocate every noble and generous act, and to perform punctually and scrupulously every treaty obligation--these are the duties which we owe to other states, and by the performance of which we best entitle ourselves to like treatment from them; or, if that, in any case, be refused, we can enforce our own rights with justice and a clear conscience. In our domestic policy the Constitution will be my guide, and in questions of doubt I shall look for its interpretation to the judicial decisions of that tribunal which was established to expound it and to the usage of the Government, sanctioned by the acquiescence of the country. I regard all its provisions as equally binding. In all its parts it is the will of the people expressed in the most solemn form, and the constituted authorities are but agents to carry that will into effect. Every power which it has granted is to be exercised for the public good; but no pretense of utility, no honest conviction, even, of what might be expedient, can justify the assumption of any power not granted. The powers conferred upon the Government and their distribution to the several departments are as clearly expressed in that sacred instrument as the imperfection of human language will allow, and I deem it my first duty not to question its wisdom, add to its provisions, evade its requirements, or nullify its commands.
