JFK sure seemed to think there was some sort of a conspiracy going on that intended to take over the world and control every human on it. Listen to the link below to hear a great Presidential speech.
Whatever he was talking about surely just went away and hasn't been plotting against us since then though...surely.
The cabal is alive and well...just watch WHO, Bill Gates, Google and FB now silencing ideas they don't like contrary to the BS the WHO/COMMUNIST China disapprove of.
It was pretty clear he was referring to the threat of international Communism and asking the press not to publish information that might be helpful to their cause. You had to live during that period (I did) to understand the real felt threat. And it was a real threat.
