The thing that strikes me about most conspiracy theorists is that they turn everyone into the all-powerful and omnicompetent incompetents around.
"We can destroy/freely manipulate the economy of anyone we choose at will but can't fix our own!"
"I can engineer a bipartisan, nationwide (if not worldwide) conspiracy from the day of my birth to get myself elected President even though I'm not an American citizen! And then I'll...uh...get really frustrated with my Congress?"
"We can run our false flag operation against the World Trade Center and the Pentagon to convince the American People to go to war, all so we can tank our economy and I can leave office with a terrible reputation that helps get the Kenyan quoted above elected!"
"We can hide evidence of the Roswell Aliens, JFK's real murderers, and the fake moon landings indefinitely, but can't stop on Army enlisted guy from blowing the lid off a ton of stuff by sending it to Wikileaks!"
