Here is a pretty good, fairly thorough, short summary about the Gladio false flag terror wave of the 1970s-80s across western Europe, well supported by official documents and facts:
https://wikispooks.com/wiki/Operation_Gladio
Operation Gladio is a NATO-backed paramilitary network established after WW2, originally inspired by fear of the USSR. It was also called the "Stay behind network", since if the Red Army invaded Europe, its members would 'stay behind' enemy lines and disrupt Soviet control. Officially non-existant, secrecy was such that these networks were hard for NATO/MI6/Deep state officials to control. Gladio was responsible for bombings, kidnappings and assassinations to such an extent that the network was publicly exposed in Italy in the 1980s and was the subject of a BBC documentary by Alan Francovich some years later.[1] The project was adapted in the mid 1990s as "Gladio B", using "Moslem terrorists" as a substitute enemy image for communists.
Operation Gladio first came to light in Italy in 1990, after over 40 years of clandestine operations. Members of the project revealed that similar projects existed in most if not all countries of Western Europe.[2] These stay-behind networks were, in essence, super secret armies in at least 14 European countries, which were kept secret from the official governmental structures of the host countries – being controlled by other forces such as the CIA and MI6. They remained mostly dormant but were also involved in anti-communist activities including anti-democratic agitation and false flag "terrorism".
The name Gladio, (or ‘Sword’ in Italian) was technically the name given to their operations in Italy, but has since come by extension to stand for the phenomenon as a whole. Evidence of such arrangements, which had been kept secret from both public and politicians democratically elected governments in the host countries for a quarter of a century was revealed through a series of scandalous revelations in Italy and other NATO countries during the 90s, and meticulously documented by Swiss historian Daniele Ganser in his 2004 book NATO’s Secret Armies,[3] arguably the most shocking book ever to be ignored by the corporate media.
The evidence contained in Ganser’s book, of terrorism directed against the people by secret armies funded and organised by NATO and answerable to deep state elements within NATO, MI6 and the CIA rather than the respective governments is so shocking that the initial reaction of most people would be to reject it. And yet the claims have been substantiated by juridical inquiries in Italy, Switzerland and Belgium and have been debated (and condemned) in the European Parliament.
Exposure
In 1984 an Italian judge Felice Casson reopened the case of a car bomb in Peteano in 1972 and uncovered a series of anomalies in the original investigation. General Mingarelli, head of the head of the caribinieri in the Udine region, was later found guilty of diverting this investigation and sentenced to 10 years (later reduced to 2½ years).[4]
Following the discovery of an arms cache near Trieste in 1972 containing C4 explosives identical to that used in the Peteano attack,
Casson's investigation revealed that although originally blamed on the communist Red Brigades, the bombing in Peteano was the work of the military secret service Servizio Informazioni Difesa in conjunction with Ordine Nuovo.
Judge Casson’s investigation also revealed that the 1972 Peteano bombing was the continuation of a series of bombings begun at Christmas 1969, the most well-known of which, on the Piazza Fontane in Milan, killed 16 and injured 80. The bombing campaign culminated on 2 August 1980 with a massive bomb in the waiting room of Bologna railway station which killed 85 and injured 200.
The Strategy of Tension
During his trial, Vincenzo Vinciguerra revealed that, in addition to discrediting left wing political groups, there had been a second aim behind the bombings -
to inculcate a climate of fear among the general populace. This was known as the 'strategy of tension' which was intended to generate a pervasive sense of fear which would encourage the population to appeal to the state for protection. As Vincenzo Vinciguerra summarized during his trial:
‘You had to attack civilians, the people, women, children, innocent people, unknown people far removed from any political game. The reason was quite simple. They were supposed to force these people, the Italian public to turn to the State to ask for greater security.’
In Francovich's documentary on Gladio, he described
the aim as to ‘destabilise in order to stabilise’… ‘To create tension within the country to promote conservative, reactionary social and political tendencies.’

In 1990 Judge Casson was given permission by prime minister Giulio Andreotti to search the archives of the Italian military secret service Servizio informazioni sicurezza Militare (SISMI) where he found proof of the existence of the Gladio network, and links to NATO and the United States. Following this, on 3 August 1990 prime minister Andreotti confirmed to parliament the existence of the Gladio networks but claimed they had ceased operating in 1972. This was subsequently revealed to be false by the Italian press. Andreotti then admitted the existence of the Gladio networks and their connection to NATO.
The secret Gladio army, as Andreotti revealed, was well armed. The equipment provided by the CIA was buried in 139 hiding spots across the country in forests, meadows and even under churches and cemeteries. According to the explanations of Andreotti the Gladio caches included 'portable arms, ammunition, explosives, hand grenades, knives and daggers, 60 mm mortars, several 57 mm recoilless rifles, sniper rifles, radio transmitters, binoculars and various tools'. Andreotti's sensational testimony did not only lead to an outcry concerning the corruption of the government and the CIA among the press and the population, but also to a hunt for the secret arms caches. Padre Giuciano recalls the day when the press came to search for the hidden Gladio secrets in his church with ambiguous feelings: 'I was forewarned in the afternoon when two journalists from "Il Gazzettino" asked me if I knew anything about arms deposits here at the church. They started to dig right here and found two boxes right away. Then the text also said a thirty centimetres from the window. So they came over here and dug down. One box was kept aside by them because it contained a phosphorous bomb. They sent the Carabinieri outside whilst two experts opened this box, another had two machine guns in it. All the guns were new, in perfect shape. They had never been used.'

But he denied the claim of Vinceguerra that the Gladio armies had been involved in the domestic terrorism the country had witnessed. Despite that,
a parliamentary commission in 2000 investigating Gladio explicitly rejected his denial and concluded to the contrary:
‘Those massacres, those bombs, those military actions had been organised or promoted or supported by men inside Italian state institutions and, as has been discovered more recently, by men linked to the structures of United States intelligence.’
