    11 Dec 41 newspaper headline announcing that Germany
    and Italy have joined Japan in declaring war on the US

    Italian dictator Benito Mussolini made his declaration first, pledging the "powers of the pact of steel" were determined to win.

    Adolf Hitler then made his announcement saying he had tried to avoid direct conflict with the US but, under the Tripartite Agreement signed on 27 Sep 40, Germany was obliged to join with Italy to defend its ally Japan. "After victory has been achieved," he said, "Germany, Italy and Japan will continue in closest co-operation with a view to establishing a new and just order."

    Hitler accused President Roosevelt of waging a campaign against Germany since 1937 and blamed him for the outbreak of war in 1939.

    Technically, the United States never "declared war" on Japan, Italy or Germany in WWII. Rather, declarations were made in Congress that formally acknowledged the "state of war" that came into existence as each of the Axis powers made their formal declarations of war, authorizing and pledging the full resources of the US government and military to bring the conflict thrust upon the United States to a successful termination.
