At present, I have to agree. However, Shirer has a slightly dissenting point of view: "The next day [08 December 1941] Hitler hurried back by train to Berlin from his headquarters at Wolfsschanze. He had made a solemn secret promise to Japan and the time had come to keep it--or break it." -- The Rise and Fall of the Third Reich Shirer quotes 'Basic Order No. 24 Regarding Collaboration with Japan' of 05 March 1941: "It must be the aim of the collaboration based on the Three-Power Pact to induce Japan as soon as possible to take active measures in the Far East. Strong British forces will thereby be tied down, and the center of gravity of the interests of the United States will be diverted to the Pacific. . . The common aim of the conduct of war is to be stressed as forcing England to her knees quickly and thereby keeping the United States out of the war." After Pearl Harbor, "Ribbentrop claimed at Nuremberg that he pointed out to the Leader that Germany did not necessarily have to declare war on America under the terms of the Tripartite Pact, since Japan was obviously the aggressor." Hitler responds. "If we don't stand on the side of Japan, the [Tripartite] Pact is politically dead. But that is not the main reason. The chief reason is that the United States is already shooting at our ships." Shirer sees Hitler becoming more irritated with the USA, Roosevelt, and America's intervention in the war. "He had a growing hatred of America." Lastly, Dr Schmidt notes, "I got the impression that, with his inveterate desire for prestige, Hitler, who was expecting an American declaration of war, wanted to get his declaration in first." "We will always strike first!" -- Hitler, per Schmidt.
