I think it is more along the lines of “this has been known for years” kind of thing. But, you are right to post it. The mainstream press has never reported this and has actually buried it. So it is new to many people. Had I not been a FR junkie I might have not known either.
But they didn’t have the Soviet archive evidence.
Without even knowing at the time about the Swimmer’s ouverture to the Soviets, I saw in 1982 how Kennedy was pushing for a “nuclear freeze” as a premise for strategic talks, which would have left USSR/Warsaw Pact with a tremendous advantage in missiles already installed.
BTW, I was stationed in Germany at the time; leftie demonstrations were everywhere against installing new Pershing III (?) missiles and they even went nuts over the brand new Patriot antimissile systems.
The crazies in Western Europe knew thay had Kennedy & others on their side. When Kennedy’s KGB connection was exposed, his chief of staff merely replied, “Well, you can’t afford to get picky in your choice of allies for the cause of world peace!”
Kennedy will not be missed.
