Operation Gladio was the codename for a clandestine "stay-behind" paramilitary network organized by
NATO, the
CIA, and
MI6 during the Cold War. While "Gladio" specifically referred to the branch in Italy, the term serves as an umbrella name for similar secret armies established across Western Europe. [1]
Core Purpose and Setup
- Soviet Invasion Strategy: The primary objective was to prepare a pre-planned underground resistance network. [1, 2]
- Guerrilla Operations: Units were trained for espionage, sabotage, and guerrilla warfare if the Warsaw Pact overran Europe. [1, 2]
- Secret Armaments: The CIA and allied agencies established hidden caches of weapons, explosives, and communications gear across the continent. [1, 2]
- Broad Footprint: Beyond Italy, networks operated in nations like Belgium, France, Germany, Greece, and even neutral countries like Switzerland and Sweden. [1, 2]
Subversion and the "Strategy of Tension"
The network's mandate mutated from defending against a foreign invasion to combating domestic left-wing political movements. [1, 2]
- Far-Right Recruitment: Intelligence agencies heavily recruited anti-communist extremists, neo-fascists, and former Nazi collaborators.
- Domestic Terrorism: In Italy, elements linked to Gladio became entangled in the "Years of Lead" (1960s–1980s).
- False Flag Operations: Operatives carried out or assisted in terror attacks blamed on far-left groups to terrify the public into supporting right-wing governments.
- Political Sabotage: The networks were used to manipulate elections, subvert socialist politicians, and maintain pro-Western alignment. [1, 2, 3, 4]
Exposure and Legacy
The secret infrastructure unraveled at the end of the Cold War, sparking widespread political outrage. [1]
- Public Revelation: Italian Prime Minister Giulio Andreotti officially exposed Gladio's existence to parliament on October 24, 1990.
- Judicial Discovery: The admission followed an investigation by magistrate Felice Casson into the 1972 Peteano car bombing.
- European Condemnation: The European Parliament passed a resolution sharply criticizing the secret military structures and demanding full investigations. [1, 2, 3, 4]
