Considering how many Americans would have been killed in an invasion of Japan, NOT using the Atom Bomb would have been a war crime. We killed more Japanese with firebombing than with the atom bomb, but Stewart probably hasn’t read enough history to even be aware of it.
The atom bomb in the end saved even more Japanese lives than American lives, according to the estimates of casualties from a land invasion of Japan.
The Japanese sowed the wind with their little fire balloon stunt trying to light California on fire. They reaped the FIRESTORM a couple years later.
If you live in rice paper houses, don't throw firebombs.
Tokyo went up like a MATCH. Waves of flames looked like the surface of the Sun. Far more died in that than in Atomic fire. But nobody cares, it is the morality of using the ultimate weapon that weighs on their conscience, not how many lives were lost or how many were saved.
