More specifically, the person who presented this was the chairman of the Joint Chiefs of Staff, and he was only removed from his position as chairman. About a year later he was appointed as Supreme Allied Commander of NATO.

And that was the last time our intelligence agencies ever planned a false flag operation in order to sway public opinion and get their way... phew!

And 18 months later Kennedy was dead and Lemnitzer was supreme allied commander of Europe

... and was later appointed by Ford to investigate the possibility of the CIA assassinating Kennedy.

It's worth noting that when this was presented to Kennedy, he didn't have the general criminally charged.

The aluminum foil hat argument here would be that this is the only reason why this is now public, and has no incidence on whether or not further (or past) US governments have actually done that.
