What are the known big conspiracies that have happened? I would argue that 9/11, JFK, Covid etc haven't been proven sufficiently, at least to the point that most everyone believes the conspiracy theory?
Another thing that is constantly talked about is false flag attacks, usually it's the other guy who engages in them or can conceive of doing one, like now with Russia. They are warning Russia can or will stage these in the war with Ukraine. What are some big false flag attacks that have been proven and perhaps admitted by the guilty party? One instance that comes to mind is the WWII Katyn forest massacre that was blamed on Nazis but was admittedly done by Russians only fairly "recently."
There have been some big coverups like I think Pearl Harbor is mentioned as one, it's claimed Roosevelt had foreknowledge, but it has not been proven sufficiently in my opinion. Many, many, including involved parties who were there, feel the USS Liberty incident was covered up to
spare Israel. Like the sailors were threatened after if they talked and many said they were afraid.
