>Hitler thus welcomed Japan's sudden entry into the war with its air raid on the American naval base at Pearl Harbor on 7 December 1941 and its subsequent declaration of war on the United States and Britain, just as the German army suffered its first military defeat at the gates of Moscow. Upon learning of Japan's successful attack, Hitler even became euphoric, stating: "With such a capable ally we cannot lose this war."[64] Preceding Japan's attack were numerous communiqués between Berlin and Tokyo. The respective ambassadors Ott and Ōshima tried to draft an amendment to the Tripartite Pact, in which Germany, Japan and Italy should pledge each other's allegiance in the case one signatory is attacked by – or attacks – the United States. Although the protocol was finished in time, it would not be formally signed by Germany until four days after the raid on Pearl Harbor.

I always thought Hitler's pact with Japan was defensive only.
