War occured between these two powers as the result of economic and political rivalry. America had long been the main influence in the pacific and South East Asia, having conquered the Phillipines, Samoa and other smaller pacific territories. The aggressive and imperialistic Japan wanted to achieve the same status in power and prestige as its American neighbour. However, the US would never allow this and in the years leading up to Pearl Harbour, attempted to stem the economic growth of Japan by placing trade tariffs (barriers) of oil etc. Ironically, these actions pushed Japan to seek colonial territories on mainland China, to aquire the resources which US had tariffed. It also brought Japan to the realisation that if it wanted a pacific empire, it would need to confront and defeat America. The rivalry came to its climax at Pearl Harbour, when Japanese bombers attempted to neutralise the US Naval Fleet. With this action, World War Two truly began.

The United States of America showed a distinct dislike for Japan, when Japan sneakily attacked Pearl Harbour. This 'Dastardly Attack' (as declared by President Franklin D. Roosevelt) led America to declare war on Japan, and a few days later, Hitler declared war on America.
