What was failing between the United States and Japan AND how did the United States

respond to Japanese aggression

1. Tensions were escalating between the United States and Japan due to Japan's aggressive imperialist expansion in East Asia, particularly its invasion of China in 1937. The United States viewed Japan's actions as a threat to regional stability and its own interests in the Pacific.

2. In response to Japanese aggression, the United States implemented a series of economic sanctions against Japan, including the freezing of Japanese assets and an embargo on oil and steel exports. These measures were intended to pressure Japan to withdraw from its conquests and end its aggression in the region. However, instead of backing down, Japan responded by launching a surprise attack on the U.S. naval base at Pearl Harbor on December 7, 1941, leading to the United States' entry into World War II.
