What was the immediate governmental response to the book Jacob Riis published?

Doolittle Raid, (18 April 1942), a surprise attack on Tokyo, Japan, by U.S. bombers during World War II. Little damage resulted, but the raid was a boost to American morale at a low point in the war. Colonel Doolittle's psychological point was to bomb Tokyo and several other Japanese cities. This did little damage. It was an important psychological point for both Americans and Japanese: Japan was vulnerable to attack. It was the first mainland bombing in Japan, it did little damage but boosted American morale.
