AnswerThe USA had already given a huge amount of aid to the British and Soviet Union and was openly hostile to the ambitions of Germany.

On an ideological level America was viewed as an inferior, racially mixed nation.

Germany and Italy had signed a pact with Japan agreeing to cooperate in establishing a new order with Germany and Italy controlling Europe and Japan controlling East Asia.

The pact also guaranteed support if any country attacked one of the Axis powers, technically once the USA had responded to the Japanese attack on Pearl Harbour by declaring war on Japan, Germany was bound to offer support to Japan.

Japan, Germany, and Italy formed the Axis Powers in World War II, therefore, due to their alliance, a declaration of war against one was perceived as a declaration against all. Germany and Italy formalized this by declaring war on the United States in retaliation for their declaration of war on Japan.
