There is only one possible standard by which to determine controversies between the United States and other nations, and that is compounded of these two elements: Our own honor and our obligations to the peace of the world. A test so compounded ought easily to be made to govern both the establishment of new treaty obligations and the interpretation of those already assumed. There is but one cloud upon our horizon. That has shown itself to the south of us, and hangs over Mexico. There can be no certain prospect of peace in America until Gen. Huerta has surrendered his usurped authority in Mexico; until it is understood on all hands, indeed, that such pretended governments will not be countenanced or dealt with by-the Government of the United States. We are the friends of constitutional government in America; we are more than its friends, we are its champions; because in no other way can our neighbors, to whom we would wish in every way to make proof of our friendship, work out their own development in peace and liberty. Mexico has no Government. The attempt to maintain one at the City of Mexico has broken down, and a mere military despotism has been set up which has hardly more than the semblance of national authority. It originated in the usurpation of Victoriano Huerta, who, after a brief attempt to play the part of constitutional President, has at last cast aside even the pretense of legal right and declared himself dictator. As a consequence, a condition of affairs now exists in Mexico which has made it doubtful whether even the most elementary and fundamental rights either of her own people or of the citizens of other countries resident within her territory can long be successfully safeguarded, and which threatens, if long continued, to imperil the interests of peace, order, and tolerable life in the lands immediately to the south of us. Even if the usurper had succeeded in his purposes, in despite of the constitution of the Republic and the rights of its people, he would have set up nothing but a precarious and hateful power, which could have lasted but a little while, and whose eventual downfall would have left the country in a more deplorable condition than ever. But he has not succeeded. He has forfeited the respect and the moral support even of those who were at one time willing to see him succeed. Little by little he has been completely isolated. By a little every day his power and prestige are crumbling and the collapse is not far away. We shall not, I believe, be obliged to alter our policy of watchful waiting. And then, when the end comes, we shall hope to see constitutional order restored in distressed Mexico by the concert and energy of such of her leaders as prefer the liberty of their people to their own ambitions.
