Since you believer (sic) there was a conspiracy behind the assassination (Moscow did it) and also that Trump is a Russian agent (Moscow did it again) then I guess you need to add (c) Both of the above.
Wouldn't that be your answer?
Dear Steve M. Galbraith,
Perhaps the following will enlighten you:
1) Although the KGB officer at the Soviet Embassy in Mexico City, Ivan Obyedkov, who volunteered the Department-13 radioactive name "Kostikov" to Oswald or an Oswald impersonator over a sure-to-be-tapped-by-CIA phone line on 10/1/63 was a Kremlin-loyal triple agent (i.e., the CIA mistakenly believed it had successfully recruited him), I don't necessarily believe Oswald killed JFK for the KGB.
2) Although the *only* reason the CIA and the FBI believed Kostikov was Department 13 in the first place was because a Kremlin-loyal triple-agent, Aleksei Kulak (J. Edgar Hoover's shielded-from-CIA FEDORA at the FBI's NYC field office), had told the FBI a year earlier that Kostikov's charge at the UN, Igor Brykin, was Department 13, I don't necessarily believe Oswald killed JFK for the KGB.
3) Although Silvia Duran and Eusebio Azcue at the Cuban Consulate described the "Oswald" they'd dealt in such a way that closely matched short, blond-haired, skinny, very thin-faced, 30-something KGB Colonel / "Third Secretary and Assistant Cultural Attache" Nikolai Leonov, I don't necessarily believe Oswald killed JFK for the KGB.
4) Although a probable KGB "mole" in the CIA's mole-hunting Office of Security by the name of Bruce Leonard Solie (look him up) probably sent former Marine sharpshooter Oswald to Moscow in 1959 as an ostensible "dangle" in a mole-protecting planned-to-fail hunt for "Popov's U-2 Mole" in the wrong part of the CIA, I don't necessarily believe Oswald killed JFK for the KGB.
5) Although Oswald said he'd sliced both wrists but Boskin Hospital said just one, I don't necessarily believe he killed JFK for the KGB.
6) Although Oswald lived half-a-mile from a KGB school in Minsk for two-and-one-half years, I don't necessarily believe he killed JFK for the KGB.
7) Although KGB true defector Major Pyotr Deriabin (1954) said Marina had to be at least a low-level KGB informant and that Oswald may have been sent back to the U.S. to do something else and "gone rogue," I don't necessarily believe Oswald killed JFK for the KGB.
8 ) Although Deriabin and KGB true defector Major Anatoliy Deriabin (December 1961) said that it was the policy of the KGB for the First Chief Directorate's Department 13 (assassinations and sabotage) to interview ALL military defectors -- yet-false-defector-in-'62-and-rogue-defector-in-'64 Yuri Nosenko, who claimed to have been Oswald's case officer, said nothing about it and neither did any of the "documents" that the Kremlin so graciously gave the U.S. after the assassination, I don't necessarily believe Oswald killed JFK for the KGB.
9) Although CIA Counterintelligence analyst Clare Edward Petty determined by reading some VENONA decrypts in the early 1970s that George DeMohrenschildt was very probably a long-term KGB "illegal," I don't necessarily believe Oswald killed JFK for the KGB.
10) Etc., Etc., Etc. (I could go on and on),
What I am sure of is that, as part of its 1959-on strategy of trying to get us to tear ourselves apart by waging Sun Tzu-like disinformation, "active measures," and strategic deception counterintelligence operations against us and our NATO allies, the KGB* has made so much "hay" from the anomaly-replete JFKA over the past sixty-two years that the conspiracy theories it has promulgated about that tragic event (and the HIV/AIDs epidemic, The Crack Cocaine Explosion in "The Ghetto," "Vaccinations Cause Autism," The Moon Landings, 9/11, Hillary's Server, etc., etc., etc.), enabled "former" KGB counterintelligence officer Vladimir Putin, with help from his professional IRA trolls, Paul Manafort, GRU officer Konstantin Kilimnik, Oleg Deripaska, Roger Stone, and Harley Schlanger (look him up), et al. ad nauseam, to install The Traitorous Orange Bird known as Donald J. Trump as our "President" in 2017 and 2025 . . . and now he's doing a bang-up job of destroying our country.
