The confluence of marginal & improbable characters surrounding Sirhan's, uhhhh, training, points to some larger questions.
One of the things that used to consistently surprise me about organized crime research, due to dumb assumptions, was the matter of agency -- that power flows from legitimate, overt government to these cut-outs and fronts; there have to be marching orders, right?. If human beings were remotely simple (or obedient), doing intelligence work would be far simpler stuff. It ain't.
We learned about mind control during the glory days of limited hangout and English majors designing lies. The narrative, as it was handed to us, should be more suspect: that the United States initiated ARTICHOKE and then MKOFTEN/ULTRA in response to the alarming potential threat of Soviet brainwashing.
Now, to be clear, there absolutely motherfucking was a huge Soviet mind control program. Which is interesting, right? It's an obvious strategic aim for any new government; a weapon you have to have to compete. (I doubt we'll see anything get declassified in China until the NPC falls in flames, but: they're currently doing anti-Islam "re-education camps", so...let's just chalk that up as a "PROBABLY SO" from the Magic 8 Ball of making sweeping claims based on zero original research. I would definitely grant that whatever program they had during the cloak and dagger 50's was run by people who were starving to death, and thus probably pretty ineffective.)
But: why would all this start after World War II? Was hypnotic or technological mind control a strategic factor in that war? More interesting still, to me, is "Why would all this start after World War II when the existence of hypnosis was a matter of public fascination for centuries already?"
I would propose that this stuff actually predates WW2. I would propose that it may stretch back centuries, especially through European royal families and through, naturally, The Jesuits, founded by a hypnotist. I would propose that this secret has been the currency of covert power for quite some time now, and is institutionalized into cultures around the world.
Which brings us back around to the question of agency again. Oglesby's Yankees and Cowboys never finished their war -- and never fully started it, either. Through institutions like the FBI and the CIA, we see permanent establishments working across, through and against each other. Through institutions like Goldman Sachs or Lockheed Martin, we see conglomerates too byzantine to even account for their own actions, ideal settings for small groups with large goals to work covertly.
As we lurch towards a century of anarchy in the USA, there are a lot of players to account for as the monoliths stop marching in formation. Surveillance states are turnkey systems now. Nuclear weapons programs are just a matter of consultants and money. Everything is for sale, and effective mind control is part of that market, too. Results are going to be disastrous for society, but good news for calloused researchers, because a lot of occult tradecraft is already spilling out into the open.
We're left to debate mechanisms -- or sadder still, the authenticity of John D. Marks or L. Ron Hubbard's muddy narratives -- while this gets operationalized against us, day after day. And just like UFOlogy, the, uhhhhh, research community around mind control sure looks like a captured, controlled environment, run by the same perps they're claiming to expose. So it's definitely worth questioning if any of the assumptions they're selling are remotely real.
