EXPLANATIONS BELOW
Concept note-1: -Some senators who opposed the Treaty of Versailles believed the proposed League of Nations would infringe upon U.S. sovereignty and Congress’s power to declare war.
Concept note-2: -Overview. 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-3: -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-4: -Weaknesses of the League of Nations: The League was supposed to present the world and encompass all countries, but many countries never even joined the organization, of which the U.S. was the most prevalent one. Some members only remained members for a short while, before ending their membership.
