It has been urged, however, that our demands required very difficult and extensive investigations, which in the midst of her embarrassments Mexico could not reasonably be expected to enter upon; but many, if not most, of the claims were in fact simple.[3.26] It has been insisted that as aggrieved Mexicans in the United States appealed to our courts, the proper policy for aggrieved Americans was to appeal to the courts of Mexico;[3.27] but the assumed analogy did not exist. The Mexican tribunals, in addition to being notoriously bad from every point of view, were sometimes deliberately used to perpetrate iniquities, and could not always enforce their fair decisions.[3.28] American writers have also argued that it was contemptible for a strong and rich nation like ours to demand money from a poor neighbor; but the extent of our national resources had no bearing on the rights of individual citizens, crippled or impoverished by Mexican injustice. This, however, is by no means all that should be said. The wisdom and the equity of the civilized world are embodied in its laws, and those laws agree that one's debts are to be paid. Spendthrifts are not exempted from the effects of this rule, and the poverty of the Mexican treasury was due not only to carelessness but also to crime. Moreover, if an amiable, "_siempre-alegre_" young man borrows without repaying, wastes his substance in riotous living, and perpetrates outrages on the passers-by, it is the duty of some creditor to bring him before the courts, and convince him in a practical manner that, as a member of civilized society, he is accountable for his acts. The same principle holds of international relations. "All political communities are responsible to other political communities for their conduct," wrote Canning to the Spanish government; Webster enunciated the same rule; and it was not only the right but the duty of the United States--as a fellow nation, a sister republic and a next neighbor--to bring Mexico to her senses by teaching her what membership in the family of nations involved. Had this been done at the beginning of her wild career, she might have put her house in order before bad practices became habitual.[3.29] Again, we shall presently find good reasons to believe, that had Mexico fairly examined our claims and frankly stated her financial difficulties, a lenient arrangement regarding what were after all moderate sums for a nation to pay could readily have been made. Further still, if Mexico was too poor to discharge her debts promptly, it was incumbent upon her, besides recognizing them, to show a certain appreciation of the indulgence accorded her; but instead of so doing she continued to harass American citizens, and showed, as we shall find, a distinct lack of good-will and even of straightforwardness in her dealings with us.
