BLUFThe Manhattan Project was the WW2 primarily USA program to produce an Atom bomb and hopefully bring WW2 to an end.
Owen Rust writing in the Collector, describes the Manhattan project when reading worth considering the following points:
- Manhattan Project began in late 1942 to develop a single bomb that would cause so much destruction that Germany and Japan would surrender unconditionally.
- Operation Downfall was to be the invasion of Japan.
- Estimated casualties for Downfall to be: 'between 1.7 to 4 million U.S. casualties, including 400-800,000 U.S. dead, and 5 to 10 million Japanese dead'.
- H-057-1: Operations Downfall and Ketsugo – November 1945 (navy.mil)
- Casualty figures were estimated based on Japanese resistance at Okinawa. See: The Bloody Hell of Okinawa | History | Smithsonian Magazine
- The U.S. detonated two A-bombs on Japan.
- Japan surrendered unconditionally six days after the U.S. dropped the second bomb on Nagasaki.
