The Doolitle Raid of April and May 1942 boosted American confidence during the World War II as it proved that Japan was vulnerable to attack.
Operation Doolittle was the first American air raid during the Second World War on Japanese territory.
The first and most important consequence of the Doolittle incursion was clearly psychological, since it was a dose of confidence for the Americans, as it showed that the Japanese Empire was vulnerable to its attacks. The direct results of the bombing in Japanese territory totaled 50 dead, 250 wounded and 90 buildings destroyed, in addition to warehouses, factories and gas tanks. The damage inflicted on the enemy by the Americans was classified as minimum.
