Answering the Argument from Numbers Involved....
From another forum....
To perpetrate this giant hoax, one would have to involve thousands of scientists, engineers, politicians, military people from at least three of the services, and god knows how many civilians. And it's held up over a period of decades. ... The ineptitude of both the government and the military to keep secrets is legend and yet you believe they have kept this giant hoax without anybody blowing the whistle. ...
The supposed bomb was shipped before supposedly being tested; the alleged test did not have the effects claimed; the bomb wasn't fitted with its aerials, which wouldn't have worked anyway; it couldn't have been aimed accurately; accounts of the aiming are wrong; the crews were isolated and the planes not watched; accounts of the effects contradict each other - the supposed 'mushroom cloud' is described in contradictory ways and was clearly an invention, and the film of it could not have been taken at the claimed time; Japanese witnesses didn't know it happened; Japanese accounts describe fire and nothing like the supposed effects of a hugely high temperature blast; aerial photography of the after-effects were indistinguishable from bombing raids of the time, with no central blast zone; the film crew specifically sent to record the event, didn't do so;
the Indianapolis which carried the supposed bomb was sunk on the voyage back to the USA, and was left four days without any assistance; the Japanese weren't told the events were 'nuclear' until long after, when they had to be told by propaganda films; trams were running three days later; the claims about shadows of bodies are wrong; there were no radiation effects; here are no seismic indicators that the supposed events took place; the story is still not consistent to this day.
The 'Holocaust' is a huge fraud which your wonderful government has done nothing to expose. Mass-murder in Armenia, the USSR and Ukraine, and in Vietnam has been covered up. The Kennedy murder, NASA and 9/11 are further examples of cover-ups. The whole paper money/ Fed issue is never mentioned by official sources. The CIA involvement in drugs, murders etc is only being uncovered by 'alternative' people.
If there are tens of thousands of scientists, engineers, politicians, military people as stupid as you, I can see no problem in hiding anything.
