Verified answer

Roosevelt was definitely a product of the old system. He established the "Roosevelt Corollary" which extended the usage of the Monroe Doctrine. On the other hand, Woodrow Wilson wanted the United States to be more involved in the world after WWI. This change from isolationism to internationalism manifested in the League of Nations. Before WWI, however, there was in fact little difference between the two of them. Wilson ran on the motto "He kept us out of the war".
