EXPLANATIONS BELOW
Concept note-1: -The League of Nations was established at the end of World War I as an international peacekeeping organization. Although US President Woodrow Wilson was an enthusiastic proponent of the League, the United States did not officially join the League of Nations due to opposition from isolationists in Congress.
Concept note-2: -Motivated by Republican concerns that the League would commit the United States to an expensive organization that would reduce the United States’ ability to defend its own interests, Lodge led the opposition to joining the League.
Concept note-3: -In 1919 the Senate rejected the Treaty of Versailles, which formally ended World War I, in part because President Woodrow Wilson had failed to take senators’ objections to the agreement into consideration. They have made the French treaty subject to the authority of the League, which is not to be tolerated.
