John Quincy Adams actually said...
If it be true that the noblest treaty of peace ever mentioned in history is that by which the Carthagenians were bound to abolish the practice of sacrificing their own children because it was stipulated in favor of human nature, I can not exaggerate to myself the unfading glory with which these United States will go forth in the memory of future ages if by their friendly counsel, by their moral influence, by the power of argument and persuasion alone they can prevail upon the American nations at Panama to stipulate by general agreement among themselves, and so far as any of them may be concerned, the perpetual abolition of private war upon the ocean.
