How did a shift in Nixon's thinking about murder weapons pave the way for SALT I?

Richard Nixon was telling Roger Stone that Lyndon Johnson murdered John Kennedy. Richard Nixon's code for the JFK as*sassi*nation was the "whole Bay of Pigs thing" which was his indictment of the CIA in the JFK assassination. LBJ indicted Texas oil and "renegade intelligence " LBJ as a diversionary tactic indicted Fidel Castro many, many times behind the scenes.
