President Arthur notified Colombia that the interference of any European power in attempting to control that canal would be regarded as an unfriendly act by the United States. We proclaimed that even a foreignbuilt and foreignowned canal would have to be controlled exclusively by America. Shall we now invite in European and Asiatic monarchies that have never acknowledged the Monroe doctrine and give over to them the control of an Americanbuilt canal? If we do. the Monroe doctrine. held sacred by our fathers. will perish by the act. the voice of monarchy and militarism will resound in our hemisphere. our own safety and tranquillity will end. our liberal institutions will perish in a colossal neglect of dutyour duty to ourselves. our duty to the Western Hemisphere. our duty to mankind.
