I only recently discovered this podcast and through the several dozen episodes I've heard, I've learned things from each one; been entertained by most and appreciated the books presented. I especially look forward to reading Richard Keer's "The Dark Side of Paradise," because he seems like an honest guy who could be a great writer.
As to the complaints about politics, other than Gen. Michael Hayden's passionate yet impeccably reasoned defense of the efficacy of torture, I found the politics rather DC normal. The complaints in these reviews seem to come from Conservatives who seek only confirmation for their delusions and grow frustrated with fact-based conversation. Their rejection of Dr. Houghton, as some sort of flaming liberal because he does describe himself as 'a liberal" is a joke. That strikes me as political filler coming from people who don't know what a hard left liberal sounds like.
Also for those who read critics of Vince Houghton's interviewing style, who claim that he is intrusive and dominates the conversation, I'd recommend his interview with Eric O'Neill, the FBI agent who trapped Robert Hanssen, which I saw as creative give & take. I'd recommend that as good place to see what you think...
Anyway, if someone wanted to listen to real people sharing what is sharable about their experience in the shadowy world of espionage, this is a very good source of credible mostly first-hand, if filtered, information.
