The fleet's route made American policy visible

Sailing first around South America turned geography into a policy message. Under Roosevelt's corollary to the Monroe Doctrine, the United States claimed the leading regional role and warned that it would intervene in debt crises rather than permit new European enclaves. Visits to Australia and Japan also addressed the changing Pacific balance after Japan's rise. Britain had converted concern about Japan into an alliance, while the United States tried to cultivate Japan and Australia as counterweights. The route reveals diplomatic priorities as clearly as it demonstrates endurance at sea.
