If the reader is interested in knowledge about the inner workings of the radical right back in the fifties or sixties, then this is a useful book. But as far as relating that group to the murder of JFK, it is simply a dud. And a pretentious, bombastic, overlong and tedious dud at that. In this reviewer’s opinion, it is the worst book on the JFK case since Ultimate Sacrifice, concludes Jim DiEugenio.

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.

What could have been an important and sterling volume is seriously compromised with a lot of litter. Instead of being up there with Rakove and Muehlenbeck, it stands a couple of steps downward, with Thurston Clarke’s mixed bag of nuts, concludes Jim DiEugenio.

About the first fifty pages of Undeniable Truths is pretty much undeniable. The next fifty pages are a decided mixture of truth and question marks. Most of the last 200 pages do not at all merit the title. In fact, that part is, in large measure, nothing more than conjecture. And much of that conjecture is ill-founded, concludes Jim DiEugenio.
