Phi Beta Iota: This is an extraordinarily good contribution–a virtual compendium of every side of the secret world. Amusingly it acknowledges that 90% of what we need to know comes from open sources of intelligence without noting the irony that we spend $80 billion on everything other than open sources. It repeats the US Government mis-conception that open sources are “second-hand,” and it neglects multinational intelligence and counterintelligence precisely because the US Government refuses to be serious about that necessary evolution. Over-all, an absolute pleasure to read, a serious contribution.
