Since trade ignores national boundaries and the manufacturer insists on having the world as a market, the flag of his nation must follow him, and the doors of the nations which are closed must be battered down. Concessions obtained by financiers must be safeguarded by ministers of state, even if the sovereignty of unwilling nations be outraged in the process. Colonies must be obtained or planted, in order that no useful corner of the world may be overlooked or left unused.

—Woodrow Wilson in an unpublished paper of 1907, as quoted in The Rising American Empire (1960) by Richard Warner Van Alstyne, p. 201
