[87], The possibility of a demonstration was raised again in the Franck Report issued by physicist James Franck on 11 June and the Scientific Advisory Panel rejected his report on 16 June, saying that "we can propose no technical demonstration likely to bring an end to the war; we see no acceptable alternative to direct military use." In 1945, the Pacific War between the Empire of Japan and the Allies entered its fourth year.
