What did the Roosevelt Corollary to the Monroe Doctrine State?

The Roosevelt Corollary of December 1904 stated that the United States would intervene as a last resort to ensure that other nations in the Western Hemisphere fulfilled their obligations to international creditors, and did not violate the rights of the United States or invite "foreign aggression to the detriment of the entire body of American nations." As the corollary worked out in practice, the United States increasingly used military force to restore internal stability to nations in the region.
