Proved true, huh. "The Business Plot" does not appear to have been proven at all. One man's testimony against that of many others. "The Manhattan Project" I would not call a conspiracy theory. Unless you consider all top secret weapon programs during time of war to be conspiracy theories. And, for matters that have been "proved true", there is quite of bit of use of the words "alleged" and "believed". All in all, not very impressive. But, you can still hold out hope for the million conspiracy theories that have not been "proved true" (and likely never will).
