When you look at LHO's peregrinations and actions after the return to America, they resemble the movements of someone who's being told he has to work something off, some debt or misdeed. Probably his precocious pro-Soviet stance in the military earned him the opportunity to become an intelligence-trained false defector, but the desire to defect was his original sin, and after his return the threat of prosecution was held over his head. Every move he made thereafter inculpated him as a dangerous influence in America, regardless the reasons given to him for making those moves.
Is that what he tried to outflank when he sought Honorable Discharge status? Maybe the dates of LHO's efforts and letters there hold a key to understanding the forces pressuring him to play Lefty Lee the Marxist, right to the end.
Was the FPCC a CIA front, an intellectuals' honey trap? Then LHO'= was a state asset. However, a "witting" (Bagley) intelligence-trained former false defector could be diverted from there into a "rogue" plot.
If we could definitely associate him with Clay Shaw, is he an asset or a patsy?
Larry, are you saying that, returned to America, LHO was never an asset, but only made to feel that he was one, and getting paid for it, so that at the end of the long game he could be set up? It seems that the chicanery with his CIA files, and a part of the later cover-up, were meant to conceal his asset status.
