After their visit to Greece , the Italian neo-fascists also engaged in false flag operations and embarked on a campaign of infiltration of leftist , anarchist and Marxist – Leninist organisations . One of the neo-fascists conducted frequent provocations and infiltrations in the months leading to the Piazza Fontana bombing on 12 December 1969 . The Greek junta was so impressed with the manner their Italian counterparts were paving the way toward an Italian coup d'état that on 15 May 1969 Papadopoulos sent them a congratulatory message stating that " His Excellency the Prime Minister notes that the efforts that have been undertaken by the Greek National government in Italy for some time start to have some impact "
