A. It showed its ineffectiveness in stopping international disputes as early as the 1930s.
B. It supported the buildup of arms in the U.S., which threatened Japan.

A. It showed its ineffectiveness in stopping international disputes as early as the 1930s.

The League of Nations was created after World War I with the goal of preventing another global conflict. However, its inability to effectively address and resolve international disputes, such as the Manchurian and Abyssinian crises in the 1930s, demonstrated its ineffectiveness as a peacekeeping organization. This failure to maintain peace and security contributed to the breakdown of global order and ultimately played a part in causing World War II.

C. It was unable to secure signatures on the Pact of Friendship in Europe.
The League of Nations' inability to establish agreements and treaties amongst European nations, such as the Pact of Friendship, further weakened its position as a mediator and arbitrator of international conflicts. This lack of unity and collaboration among member states undermined the League's credibility and ability to prevent aggression, ultimately paving the way for the outbreak of World War II.

Overall, the League of Nations' failure to effectively address disputes and secure agreements among nations ultimately contributed to the breakdown of global order and the eruption of World War II.
