Investigative journalism is usually worthwhile reading, and The Secret War with Iran is no exception. Ronen Bergman's book, published in 2009, is, or can be, a difficult one to read in that, as he writes, there was no intention to write only about failures in Israeli and American intelligence, but unfortunately there were many important ones about which there had to be exposure. And, I would hope, that exposure will have, or will, in the future, serve as a preemptive warning re: such future failures. The book also includes the many successes, of course, and, in total, is an important historical report on Iran, Hamas, Hezbollah, Syria, and the war against the West and by the West against Iran and its proxies in the Middle East.
It seems, however, that today, warnings from Bergman's work, is being ignored by our current administration. Only time will tell.
One other point I would like to make. I rated this book 5 stars, as I have with a number of others I have read. I give that rating based upon the value of those non-fiction works - when they make you think, when they are relevant, then the 5 stars is appropriate; this book without question meets that criteria.
