As early as 1914 the Japanese and Americans were thinking of each other as possible future enemies. This potential came more sharply into focus when in the 1930s Japan openly embarked on a path of aggression. Beginning in 1931, Japanese actions clearly indicated that their goal was to dominate East Asia. The central issue between Japan and the United States in the period leading up to war was Japanese aggression in China. Not only did this aggression threaten China's integrity, but it jeopardized American trade interests. Despite the fact that it was not one of its primary national security interests, the United States remained committed to Chinese sovereignty. As the Japanese pressed deeper into China and prosecuted the war with increasing brutality, the Americans began to translate Japanese dependence on resources from the United States into economic pressure. Throughout 1940 the US ratcheted up the economic pressure on Japan in an attempt to curb Japan's imperial ambitions without war.
