“Ironic that Dulles, who he fired as head of the CIA was on the Warren Commission.”
Not ironic at all. As an infiltrator, he had a purpose.
There were two named “Dulles” at high levels when all of this was going on. Brothers, I think. They were making decisions and taking actions without JFK’s knowledge — running things behind his back. IIRC, JFK fired both of them.
It was Allen and John Foster Dulles. John Foster, who the DC Airport is named after was United States Secretary of State under President Dwight D. Eisenhower from 1953 until his resignation in 1959 (due to his colon cancer diagnosis) and was briefly a Senator from New York in 1949.
