Status	PARTIALLY SUBSTANTIATED
Summary	Operation Gladio refers to clandestine 'stay-behind' armies organized by NATO and Western intelligence agencies during the Cold War to resist a potential Soviet invasion or communist takeover. Proponents claim these networks were involved in covert operations, including terrorism and political manipulation, that were kept secret from public and parliamentary oversight. The existence of such networks was confirmed in the 1990s, but the extent of their involvement in domestic terrorism remains disputed.
Origin	The concept originated in the early Cold War, with roots in World War II resistance organizations like the Special Operations Executive (SOE). The Italian branch, codenamed Gladio, was exposed in 1990 by Italian Prime Minister Giulio Andreotti.
Claimed	NATO and the CIA organized secret stay-behind armies across Western Europe to counter Soviet invasion and communist parties. These networks operated outside parliamentary control and were involved in covert actions, including bombings and assassinations, to discredit left-wing groups. The Italian Gladio network was linked to the 1969 Piazza Fontana bombing and other 'strategy of tension' attacks. Similar networks existed in many countries, including Belgium, Germany, Greece, and Turkey, with various codenames. The US and UK intelligence agencies (CIA and MI6) provided training and support, sometimes recruiting former Nazis and right-wing extremists.
Evidence / consensus	Historical evidence and official investigations confirm the existence of NATO stay-behind networks, including Gladio, and their secret nature. However, direct involvement in specific terrorist attacks remains unproven and is contested by many historians and official inquiries.

> OBSERVER NOTE:
File contains verified existence of clandestine networks, but the darker allegations of state-sponsored terrorism remain murky. The line between contingency planning and active subversion is thin and poorly documented.
