I think your instinct is correct but you are missing a few things.
Nearly all high ranking intelligence official or bureaucrats from the 60’s, 70’s 80’s who have decided to “come clean” will point the finger at the USSR.

They only required a couple dozen conspirators to execute the coup.
They needed several hundred or thousand to cover it up.
They told these 2nd and 3rd level conspirators that the USSR killed Kennedy and left LBJ with 2 choices. He could either cover it up and “pretend” that Oswald acted alone or he could start a full thermonuclear war which would almost certainly end all human life on the planet.
That was the original limited hangout. Those who helped cover up the assassination, thought they were the “good guys” helping to save humanity. They didn’t think they were “bad guys” helping to coverup a coup and the murder of an innocent man.
The mention of the mob was introduced later to further cloud public opinion.
I think you splitting #2, #3 and the truth into separate sections is superfluous and unnecessary. There were many more reasons than Israel getting the bomb. The coup also had to do with defense contractors and Vietnam and central banks.
The result of the operation was ultimately the removal of a representative government by the people and the installation of a government by the globalist oligarchs.
The CIA was the tool that was used to accomplish it. These globalist oligarchs have been using them to move chess pieces on the board ever since.
Angleton was in the pocket of Mossad.
He was the “key player”.
Nothing makes sense if you ignore this element.
