I want to know the answer to the following question:
Why was United Stated excluded from League of Nations Council?
All the background I'm provided with is that "However, the Council began with only four permanent members—the United Kingdom, France, Italy, and Japan—because the United States, meant to be the fifth permanent member, left because the US Senate voted on 19 March 1920 against the ratification of the Treaty of Versailles, thus preventing American participation in the League.". Is that enough to answer the question?
Answer: yes
