“The moral strength of a nation is revealed in how it treats those with no voice. Children, the poor, the sick, and minorities are not burdens but tests of collective conscience. A state that protects them protects its own future. Indifference is the most dangerous form of neglect.”

Message to Congress withdrawing a treaty for the annexation of Hawaii from consideration. (18 December 1893); A Compilation of the Messages and Papers of the Presidents 1789-1897 (1896 - 1899) edited by James D. Richardson, Vol. IX, pp. 460-472.
Context: It has been the boast of our government that it seeks to do justice in all things without regard to the strength or weakness of those with whom it deals. I mistake the American people if they favor the odious doctrine that there is no such thing as international morality; that there is one law for a strong nation and another for a weak one, and that even by indirection a strong power may with impunity despoil a weak one of its territory.
By an act of war, committed with the participation of a diplomatic representative of the United States and without authority of Congress, the government of a feeble but friendly and confiding people has been overthrown. A substantial wrong has thus been done which a due regard for our national character as well as the rights of the injured people requires we should endeavor to repair. The Provisional Government has not assumed a republican or other constitutional form, but has remained a mere executive council or oligarchy, set up without the assent of the people. It has not sought to find a permanent basis of popular support and has given no evidence of an intention to do so. Indeed, the representatives of that government assert that the people of Hawaii are unfit for popular government and frankly avow that they can be best ruled by arbitrary or despotic power.
The law of nations is founded upon reason and justice, and the rules of conduct governing individual relations between citizens or subjects of a civilized state are equally applicable as between enlightened nations. The considerations that international law is without a court for its enforcement and that obedience to its commands practically depends upon good faith instead of upon the mandate of a superior tribunal only give additional sanction to the law itself and brand any deliberate infraction of it not merely as a wrong but as a disgrace. A man of true honor protects the unwritten word which binds his conscience more scrupulously, if possible, than he does the bond a breach of which subjects him to legal liabilities, and the United States, in aiming to maintain itself as one of the most enlightened nations, would do its citizens gross injustice if it applied to its international relations any other than a high standard of honor and morality.
On that ground the United States cannot properly be put in the position of countenancing a wrong after its commission any more than in that of consenting to it in advance. On that ground it cannot allow itself to refuse to redress an injury inflicted through an abuse of power by officers clothed with its authority and wearing its uniform; and on the same ground, if a feeble but friendly state is in danger of being robbed of its independence and its sovereignty by a misuse of the name and power of the United States, the United States cannot fail to vindicate its honor and its sense of justice by an earnest effort to make all possible reparation.

Context: There will be no peace in Europe if the States rebuild themselves on the basis of national sovereignty, with its implications of prestige politics and economic protection…. The countries of Europe are not strong enough individually to be able to guarantee prosperity and social development for their peoples. The States of Europe must therefore form a federation or a European entity that would make them into a common economic unit.
