U.S. Ambassador Joseph Grew implored Washington not to ignore Konoye’s offer, that the prince had convinced him an agreement could be reached on Japanese withdrawal from Indochina and South and Central China. Out of fear of Mao’s armies and Stalin’s Russia, Tokyo wanted to hold a buffer in North China.

On Aug. 28, Japan’s ambassador in Washington presented FDR a personal letter from Konoye imploring him to meet.

Tokyo begged us to keep Konoye’s offer secret, as the revelation of a Japanese prime minister’s offering to cross the Pacific to talk to an American president could imperil his government.

On Sept. 3, the Konoye letter was leaked to the Herald-Tribune.

On Sept. 6, Konoye met again at a three-hour dinner with Grew to tell him Japan now agreed with the four principles the Americans were demanding as the basis for peace. No response.

On Sept. 29, Grew sent what Hoover describes as a “prayer” to the president not to let this chance for peace pass by.

On Sept. 30, Grew wrote Washington, “Konoye’s warship is ready waiting to take him to Honolulu, Alaska or anyplace designated by the president.”

No response. On Oct. 16, Konoye’s cabinet fell.

In November, the U.S. intercepted two new offers from Tokyo: a Plan A for an end to the China war and occupation of Indochina and, if that were rejected, a Plan B, a modus vivendi where neither side would make any new move. When presented, these, too, were rejected out of hand.

At a Nov. 25 meeting of FDR’s war council, Secretary of War Henry Stimson’s notes speak of the prevailing consensus: “The question was how we should maneuver them (the Japanese) into … firing the first shot without allowing too much danger to ourselves.”

“We can wipe the Japanese off the map in three months,” wrote Navy Secretary Frank Knox.

As Grew had predicted, Japan, a “hara-kiri nation,” proved more likely to fling herself into national suicide for honor than to allow herself to be humiliated.

Out of the war that arose from the refusal to meet Prince Konoye came scores of thousands of U.S. dead, Hiroshima, Nagasaki, the fall of China to Mao Zedong, U.S. wars in Korea and Vietnam, and the rise of a new arrogant China that shows little respect for the great superpower of yesterday.

If you would know the history that made our world, spend a week with Mr. Hoover’s book.
