Oh damn. Yeah that’s a rabbit hole I have certainly never gone down. Never even heard of it, but might be fun to explore it. I find that one hard to accept though because the propaganda it would take to convince the Japanese that there was a bomb that destroyed entire cities that didn’t actually happen or with fake images of the aftermath would be a very complex undertaking with many many “leaks” in the narrative, imo.
I could certainly believe that the magnitude and power of the ones that are supposedly “a thousand times bigger than Nagasaki!!!” Is overblown bullshit and we don’t actually have bombs big enough to wipe out the bottom third of the eastern United States. But that they don’t exist at all is a road I have never ventured down 🤔
