EXPLANATIONS BELOW
Concept note-1: -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: -On February 28, 1919, Senator Henry Cabot Lodge of Massachusetts began an assault on President Woodrow Wilson’s proposal to establish a League of Nations that ultimately culminated in the Senate’s rejection of the Treaty of Versailles.
Concept note-3: -The United States never joined the League. Most historians hold that the League operated much less effectively without U.S. participation than it would have otherwise. However, even while rejecting membership, the Republican Presidents of the period, and their foreign policy architects, agreed with many of its goals.
Concept note-4: -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.
