It’s my understanding that the CIA was created by Truman. And I’ve read more than one account of his angst after the Kennedy assassination and the op-ed he wrote about the CIA being dangerous to the country and he wished it could be disbanded. Over 50 years ago. But he’d unwittingly created a monster.
Many good Americans still refuse to believe the CIA could have ever been involved in that. No way could there have been conspiracies at that level. Poppycock. Now? I would say it’s a safe bet most of those folks no longer subscribe to that notion.
