Once was enough

“Some historians, armed with knowledge of subsequent events, argue that the capture of Okinawa was unnecessary. It did not bring Japan’s surrender a day closer. Yet to those directing the operation at the time, it was perceived as an indispensable preliminary to invasion of the Japanese home islands. [The Battle of] Okinawa exercised an important influence on the development of events thereafter, through its impact upon the civilian, military and naval leadership of the United States. To capture an outpost, American forces had been obliged to fight the most bitter campaign of the Pacific war. The prospect of invading Kyushu and Honshu in the face of Japanese forces many times greater than those on Okinawa, and presumably imbued with the same fighting spirit, filled those responsible with dismay. . . . [A]ny alternative which averted such necessity would be deemed welcome.” – Max Hastings, Retribution
