Review title: Clear & convincing
Product review: As others note here, this is a well-written and exhaustively researched account of the role of submarines in undercover operations during the Cold War. It contributes major understanding about that era. Inevitably, it asks whether the risks and expense were worth it; but it offers no answer. Here's one: Spying provided incontrovertable information to each side about the other's intentions, thus reducing threat of nuclear war. The effort was worth it, not for what it achieved,but for what it prevented. Everyone involved in these operations (even traitorous spies) helped prevent nuclear war. To those who did so from courage, their nation owes gratitude as surely as to those faced the perils of a shooting war.
