"Much of the social warfare between the United States and Japan involved instilling within their people both a strong nationalistic pride for their own country as well as an incendiary hatred for the other. This was done with the help of the media—newspapers, books, radio, and film—that were consequently used as propaganda against the enemy. Much of the material was racist and catered to such ideas as racial inferiority and ethnic supremacy. One’s own nation was always the civilized one while the enemy was depicted as barbaric, sub-human, and in some cases, demonic.
he United States was not fighting Japan simply because of their surprise bombing of Pearl Harbor. There are even those who might say that the attack really should not have come as much of a surprise at all, that the United States methodically provoked the Japanese to attack in order to give the United States a reason to jump into the war. Up until that point, the United States had only moderately contributed on the European front, and was looking for a way to join in the fight. The reasons for the United States entering the war vary, and it would be difficult to argue that they entered the war for any one sole reason. One explanation is for economic reasons. The war created jobs and boosted domestic industry. In Asian, Japan was building a stronghold of Asian nations that included China, Korea, and also the Philippines, which the United States had vested interest in and to whom they were still a major influence. The United States still had valuable assets that they needed to protect in Asia, as did European nations, such as Great Britain and France who still held colonies in Singapore, Hong Kong, and French Indochina.
