When reflecting upon it today, that the Pearl Harbor attack should have succeeded in achieving surprise seems a blessing from Heaven. It was clear that a great American fleet had been concentrated in Pearl Harbor, and we supposed that the state of alert would be very high.
The moment the first American soldier sets foot on the Japanese mainland, all prisoners of war will be shot.
Despite Japan's desires and efforts, unfortunate differences in the ways that Japan, England, the United States, and China understood circumstances, together with misunderstandings of attitudes, made it impossible for the parties to agree. Up until the very end, these were important reasons for the outbreak of war, and from Japan's point of view, this is a matter of great regret.
