His corollary to the Monroe Doctrine prevented the establishment of foreign bases in the Caribbean and arrogated the sole right of intervention in Latin America to the United States. He won the Nobel Peace Prize for mediating the Russo-Japanese War, reached a Gentleman's Agreement on immigration with Japan, and sent the Great White Fleet on a goodwill tour of the world. Some of Theodore Roosevelt's most effective achievements were in conservation. He added enormously to the national forests in the West, reserved lands for public use, and fostered great irrigation projects. He crusaded endlessly on matters big and small, exciting audiences with his high-pitched voice, jutting jaw, and pounding fist. "The life of strenuous endeavor" was a must for those around him, as he romped with his five younger children and led ambassadors on hikes through Rock Creek Park in Washington, D.C. Leaving the Presidency in 1909, Roosevelt went on an African safari, then jumped back into politics. In 1912 he ran for President on a Progressive ticket. To reporters he once remarked that he felt as fit as a bull moose, the name of his new party. While campaigning in Milwaukee, he was shot in the chest by a fanatic. Roosevelt soon recovered, but his words at that time would have been applicable at the time of his death in 1919: "No man has had a happier life than I have led; a happier life in every way.".
