What the author is doing has three layers.  First, he is giving us a history of the Castro revolution.  At the same time he is showing how the USA reacted to that epochal turnover, stage by stage in its evolution. Third, he is tracing certain people and movements who will return to the stage in 1963, after Kennedy changes policy, and begins a détente attempt with Cuba.  Other authors have tried this before, but never on this scale or with this intricacy, writes Jim DiEugenio.
