Allen Dulles, mastermind of it all?

Still trying to wrap my head around the fact that former OSS/CIA head and founder Allen Dulles is linked to:

Project Paperclip MKUltra Assassination of JFK The UFO coverup Funding of Nazis and Fascists Government coups The looting of Yamashito’s treasure (big money)

What did I miss?

Thanks to u/36_39_42 for the lead.
