Didn’t know that about the stock market.
As for the raid, a Japanese fishing boat saw the carrier two hundred miles beyond what the range of the raid was meant to be. Figuring the jig was up, they launched anyway. Not much time to linger on target, but what damage was done was mostly psychological anyway.
Yamamoto was in the process of trying to get the Japanese Army to go along with his plans for the next step of the war. The Japanese were suffering from “victory fever” stemming from the success of Pearl Harbor, et al, and wanted the country to do something.
The Doolittle raid shocked the military into giving Yamamoto a mostly free hand, resulting in their disastrous attack on Midway Island, breaking the back of the IJN.
Yes. Japanese leadership had told the people they would never be bombed. Even though the damage caused by the Doolittle Raid was minimal the psychological shock was great. So the Japanese decided on the Midway operation in an attempt to destroy the remaining US Pacific fleet. They lost three carriers and in truth never recovered. We built thirty-three fast carriers during the war. The Japanese built .... none.
The Chinese paid a very heavy price for supporting airmen in the Doolittle raid. I have read that over 200k Chinese were butchered for the assistance.
