Hiroshima Revisited: The Evidence that Napalm and Mustard Gas Helped Fake the Atomic Bombings by Michael Palmer (and Franklin Stahl) argues that the 1945 destruction of Hiroshima and Nagasaki was not caused by atomic bombs, but by conventional napalm and mustard gas attacks. The book claims official records were fabricated, using "pumpkin bombs" (conventional explosives) to fake a mushroom cloud. The book challenges the established historical narrative, suggesting a cover-up regarding the true nature of the destruction.
