Hi Jon, I looked thru the Atlantic website and found the following; "During coffee, the talk turned to President Kennedy, and Johnson expressed his belief that the assassination in Dallas had been part of a conspiracy. "I never believed that Oswald acted alone, although I can accept that he pulled the trigger." Johnson said that when he had taken office he found that "we had been operating a damned Murder Inc. in the Caribbean." A year or so before Kennedy's death a CIA-backed assassination team had been picked up in Havana. Johnson speculated that Dallas had been a retaliation for this thwarted attempt, although he couldn't prove it."
As you can see, no mention of the "Russians". If you know of another reference to Russia that I may have missed, could you post a link to it, please? Also, in Johnson's own words, his suspicions were just speculations. Former President or not, I don't hold Johnson's 'speculations' any higher than I would anyone else's.
As for the rest of your post, FWIW, I can't find too much I'd disagree with. I've often suggested that Oswald was playing a 'game' of spymaster with himself and in that capacity may have been a low-level snitch for one or more of the agencies, not important enough to be an asset, certainly not an agent. Just a 'snitch' occasionally coming up with something useful.
Consider that Eisenhower gave Nixon and the Dulles brothers broad leeway. The folder dated 2009 of the list of claims against the Castro regime is over 300 pages. Freeport Minerals direct losses may have been closer to $100 million than $50. Was LBJ intimating the Kennedy Bros. came along and built a new culture and S.O.P. inside CIA, and so quickly?
In 1961 the U.S. was nearly unrivaled in economic power and faced only one serious military adversary. All indications are Allen Dulles drank
his own kool-ade and talked his own book, predatory capitalism. The taking of Cuba could not stand, as a point of pride, precedent, the example it would set, and obviously the pain felt in the wallet. A description of the father-in-law of Edith Dulles Snare.:

I see corporatist concentration of political influence in that the two
parties, Freeport Sulphur and Frederick Snare Corp. that had been doing quite well taking US government subsidy to the tune of $40 million.
The part about Dulles brother's first cousin and widow of Frederick Snare, Jr. hosting the Iranian ambassador in her home in 1958 indicates to me she and her cousin Foster had an understanding . Frederick Snare Corp. as of 2009, was still listed with a claim amounting to $1.8 million against the Castro government.

Call me crazy, but the indications in the details I have posted in this thread support a Dulles and Langbourne Williams families conspiracy to
recover their losses in Cuba and then mop up the "loose ends" in the example of Stuart Johnson falling at the home of a Dulles cousin, and
in the pressure exerted on Billy Joe Lord, even more so considering Henry Hurt and Bemiss who Lord claimed Hurt consulted on pressure tactics to draw from to pressure Lord's cooperation. Fitzgerald "Gerry" Bemiss was a cousin of Freeport's president Langbourne Williams and Henry Hurt just so happened to have resided in tiny Kennebunkport immediately before marrying Langbourne Williams's brother's daughter.
