The idea that conventional explosives can split an atom causing it to split https://heiwaco.tripod.com/bomb.htm other atoms in a chain reaction is totally absurd. It's the bogus Big Bang theory on a micro level. As above, so below. Hiroshima & Nagasaki were fire bombed like all the other cities. The alleged radiation burns were from phosphorus & napalm. They rebuilt those cities with no concern about alleged radiation. For the tests they stacked tons of TNT in the desert & blew it up, hence the carbonaceous fireball, a conventional explosion. They also used Lookout Mt film lab for special effects. It's all science fiction, like the mumbo jumbo of astrophysics with the propped up front man Einstein, a high school drop out. The nuclear hoax allowed communism to keep the territory the West helped them take. The J-bomb is another big lie, like evolution & outer space. It's the bogeyman meant to scare us into the NWO. The bombing of whole cities by America & Britain during WW2 has got to be the greatest war crime of all time, but no trials are held for the victors. They write the history, a set of lies agreed upon.
