Operation Gladio

NATO secretly armed and trained paramilitary networks across Western Europe to resist a Soviet invasion that never came — and Italy's own prime minister had to publicly confirm it existed after decades of official denial.

Operation Gladio was the Italian codename for a network of clandestine NATO-backed "stay-behind" paramilitary organizations established across Western Europe during the Cold War, intended to resist a potential Soviet occupation. Their existence was officially confirmed by Italian Prime Minister Giulio Andreotti in 1990, and some networks have been separately linked to allegations of domestic political violence.
