====Japanese Invasion of Manchuria alarmed the Hoover administration====

The Japanese invasion of Manchuria and subsequent push to gain control over larger expanses of Northeast China in 1931 led President Herbert Hoover and his Secretary of State, Henry Stimson, to establish the Stimson Doctrine, which stated that the United States would not recognize the territory gained by aggression and in violation of international agreements. With the Stimson Doctrine, the United States expressed concern over the aggressive action without committing itself to any direct involvement or intervention. Other conflicts, including the Italian invasion of Ethiopia and the Spanish Civil War, also resulted in virtually no official commitment or action from the United States Government.
