Operation Gladio: Europe’s Secret Armies

Episode Description from the Publisher

In 1990, Italy admitted the existence of Operation Gladio: a secret Cold War stay-behind network built to resist a Soviet invasion that never came. But when hidden weapons caches, intelligence links, and decades of political violence came into view, Europe was forced to ask a darker question: had secret armies created to defend democracy become a threat inside democracy itself?This episode of Unexplained History investigates the documented reality of Gladio, the European Parliament’s alarm over clandestine networks outside democratic control, and the unresolved allegations connecting Cold War security structures to Italy’s Years of Lead, the Piazza Fontana bombing, and the chilling idea of a “strategy of tension.” The truth is not as simple as conspiracy or coincidence — and that is what makes Gladio so disturbing.Become a supporter of this podcast: https://www.spreaker.com/podcast/unexplained-history--6429156/support.🎧 Unexplained History explores the myths, mysteries, and misunderstood moments that shaped our world.
