The united states senate rejected united states membership in the league of nations after world war i mainly because its senate opponents? a. did not wish to give financial aid to an international organization b. feared that membership would infringe upon united states national sovereignty c. believed that membership would end united states participation in military alliances d. was more concerned about the domestic problems created by the great depression

The correct answer is B. Feared that membership would infringe upon United States national sovereignty.

The faction of the US Congress that rejected joining the League of Nations was worried that participation in this organization would result in America getting forced into fighting foreign wars that they had no interest in. After World War I, many of these politicians wanted to return to a policy of isolationism. In order to do this, they needed to avoid permanent foreign alliances.
