"The Japanese followed a very resolute tactic in unleashing this conflict. They simply pounced on the enemy that wanted to strangle them and attacked him. I trust that the Japanese still have a few things in reserve; for they generally pursue very cautious, traditionally conservative policies; they will not negligently risk their empire, and they surely have a whole series of military options, about which even we know nothing. They did not inform us in advance of their intention to attack suddenly, and this was also necessary to maintain the secrecy of their plans. All these events are still rather unclear for the time being. But the war is a fact. Tojo was more dependable after all than we had assumed at first. The Führer and the whole headquarters are overjoyed at this development. We are now at least temporarily secure from a serious threat. In the coming weeks and months Roosevelt will no longer be as insolent as he has been in the past. Now this war has become a world war in the true sense of the word."
