If a nation shows that it knows how to act with reasonable efficiency and decency in social and political matters, if it keeps order and pays its obligations, it need fear no interference from the United States. Chronic wrongdoing . . . may . . . ultimately require some intervention by some civilized nation, and in the Western Hemisphere the adherence of the United States to the Monroe Doctrine may force the United States, however reluctantly, in flagrant cases of such wrongdoing . . ., to the exercise of an international police power.
—President Theodore Roosevelt, Annual Message to Congress, December 6, 1904
