I do not believe Oswald was a false defector or tool of the KGB.
Whether or not Oswald killed JFK for the KGB, wouldn't his being sent to Moscow (thinking he was on a mission for the CIA) to unwittingly protect the KGB mole in the CIA who had sent him make him a tool of the KGB?
I think this is the game of Newman, Morley and others - they dazzle their followers with so many names, acronyms and dubious "smoking gun" documents and so much dark speculation that the followers fail to notice that nothing but the dark speculation really has anything to do with Oswald or the JFKA.
It seems to me that Newman's and Morley's and DiEugenio's, et al. ad nauseam, "dark speculations" about the CIA's (or the Army's) putative use of Oswald in the JFKA are based on their gullible acceptance of KGB disinformation and their concomitant hatred of "The Deep State" / 'National Security State."
What's
not based on KGB disinformation is 1) Newman's realizing way back in 1995 that the incoming non-CIA cables about Oswald's defection didn't go to where they should have gone in the Agency -- the Soviet Russia Division -- but to the mole-hunting Office of Security (where naive Angleton's confidant, mentor, and mole-hunting superior, Bruce Solie, was the CIA's principal mole hunter), 2) his learning from Tennent H. Bagley's 2007 Yale University Press book,
Spy Wars, that Yuri Nosenko (who was eventually "cleared" by Solie in 1968) was a false defector sent to the CIA in Geneva in 1962 to divert attention away from the "mole" (Solie) who had betrayed Popov way back in early 1957, and 3) his finding Solie's travel documents on genealogy.com -- which show his highly unusual trip to Beirut in February 1957 and his two trips to Paris within 30 days in mid-1962.
For these discoveries / realizations, John "Nut Case" Newman is to be commended, IMHO.
