President Wilson was completely devastated by World War I, but even more so after the war.  He wanted to create the league of nations to prevent another world war, but the American public didn't go along with the idea.  So Wilson toured all over the United States to garner support, but to no avail.  The senate confirmation bill to ratified the league of nations was voted down.  Afterward, he lived a life of a ghost, finally dead a year later, a broken man.\n\nFor Roosevelt, he wanted to realize his goal of the four world policeman to prevent another world war. He had litte doubt that the allies would win the war. Therefore, he focused most of his efforts with secret diplomacy with Stalin, the best known being the "blue pencil" agreement.  Stalin always carried a blue pencil around.  When Roosevelt was discussing post war world with Stalin, Stalin took out a pencil and basically draw out parts of Eastern Europe as the Soviet sphere, American sphere and British sphere. However, Roosevelt never saw his plans become reality and he kept all of it secret from his vice president, Harry Truman.
