This is pretty outrageous stuff, but it is either true or it isn't.
If Corso is telling the truth, this is likely the prime mover behind this "space force" idea...that and China, of course.
BTW, Corso was on the staff of President Eisenhower's National Security Council for four years (1953–1957).
In 1961, he became Chief of the Pentagon's "Foreign" Technology desk in Army Research and Development, working under Lt. Gen. Arthur Trudeau.
Am inclined to mostly believe Corsi. Hard to discern which specifics might be misinformation or disinformation. By almost all accounts, he believed what he published.
