No one appreciated America’s emerging influence more than the man who, after William McKinley’s assassination, became president in 1901. Theodore Roosevelt was an avid student of world affairs who called on “the civilized and orderly powers to insist on the proper policing of the world.” He meant, in part, directing the affairs of “backward peoples.” For Roosevelt, imperialism went hand in hand with domestic progressivism. He argued that a strong federal government, asserting itself both at home and abroad, would enhance economic stability and political order. Overseas, Roosevelt sought to arbitrate disputes and maintain a global balance of power, but he also asserted U.S. interests.
