Conspiracy is a great study often with much speculation upon facts along with some personal baggage.Pearl Harbor is a great study of this phenomenon of personal distortion of hindsight.
What is funny about conspiracies is that people get called conspiracy theorists then years later the records get released proving what was said all along. Look at how many years people said the government started the fires at the Branch Davidian Compound in Texas run by David Koresh in 1993. 80 people were killed including 23 children. But the government kept claiming Koresh started the fires until a few years ago after everyone had forgotten what happened. The a government spokesperson made an announcement on the news that the records showed that Koresh DID NOT start the fires and that the fires were in fact started by Federal agents.
And look at the JFK incident. If they have nothing to hide then why have they sealed the records until something like 2030 after everyone involved will be long dead?
