Difficulty: MediumWorld War I: Diplomacy, Military, and Postwar Peace

"It is either the League of Nations or a return to the old system of alliances, the system of balance of power, which has always broken down and will always break down. The League of Nations is the only hope of the world. . . . If we do not make the League of Nations a reality, we will have to maintain a great standing army, we will have to be ready for war at any moment, we will have to live in a state of constant tension."
— President Woodrow Wilson, Speech in Pueblo, Colorado, September 1919

Which of the following best explains why the United States Senate ultimately rejected the treaty that contained the organization advocated in the excerpt?

  1. Concerns that joining the organization would compromise United States sovereign authority to declare war and make foreign policy decisionsAnswer
  2. B
    A widespread public desire to return to a policy of absolute isolationism, completely cutting off all economic and trade relations with European nations
  3. C
    The belief that the treaty violated the Monroe Doctrine by committing the United States to establish a permanent military alliance with Latin American nations
  4. D
    Popular anger over the sinking of the Lusitania, which led Congress to demand a declaration of war against Britain and France instead

Answer

Concerns that joining the organization would compromise United States sovereign authority to declare war and make foreign policy decisions
The correct answer is correct because the chief obstacle to the ratification of the Treaty of Versailles in the United States Senate was the concern that Article X of the League of Nations Covenant would mandate military action, thereby undermining Congress's constitutional power to declare war.

Step-by-Step Solution

1
Identify the historical context and the primary advocate in the source.
The excerpt shows President Woodrow Wilson defending the League of Nations in late 1919.
This establishes that the core debate centers on the ratification of the Treaty of Versailles and the League Covenant.
2
Analyze the arguments raised by the domestic opposition in the Senate.
Critics, notably Senator Henry Cabot Lodge and the Reservationists, feared that Article X would bypass Congress's constitutional authority to commit American troops to conflict.
This explains the specific political conflict that prevented the United States from ratifying the treaty.
3
Evaluate the choices to select the statement that accurately represents the Senate's motives.
The choice highlighting sovereign authority and the power to declare war correctly explains the Senate's rejection, while the other choices present historical inaccuracies or misconceptions about interwar policy.
This confirms the correct option based on historical evidence.
