THE MAIN OBJECTIVE in American foreign policy since 1900 has been the preservation of the British Empire. Intimate ties between Britain and the United States were first forged in 1898 when Britain realized that her policy of isolation had deprived her of any faithful allies upon whom she could depend in the event of war. The guns that brought victory to Admiral Dewey at Manila Bay sounded a new note of authority in the Far East and made the British Government aware of the fact that America could be made into a useful guardian of the life lines of empire. With John Hay as Secretary of State it was not difficult for the Foreign Office to arrive at an understanding with the United States that was as intimate as it was informal.

The first Open Door note of September 6, 1899, was an exercise in Anglo-American co-operation, with Alfred E. Hippisley giving an interesting demonstration of how helpful a British official could be in the drafting of American diplomatic notes. Theodore Roosevelt was evidently impressed with this growing Anglo-American accord, and when certain European powers threatened to intervene in the war Britain waged against the Boers in South Africa, he sounded a note that became very familiar in the eventful years that preceded the outbreak of World War II: "Real liberty and real progress are bound up with the prosperity of the English-speaking peoples. .. . I should very strongly favor this country taking a hand .. . if the European continent selected this opportunity to try and smash the British Empire."1
