[3] Giannettini participated in a colloquium on "revolutionary warfare" on 3–5 May 1965 in Rome (Parco dei Principi hotel), which was organized by the Institute Alberto-Pollio, "quasi-exclusively financed by the SIFAR"[5] military intelligence agency.

"[6] Following this colloquium, in which about 20 students participated (among them, Stefano Delle Chiaie and Mario Michele Merlino[6]), Giannettini and other intervenants were hired by the Italian secret services.

[6] According to Frédéric Laurent, author of L'Orchestre noir (p. 75), "more than half of the Italians (...) returned from Athens suddenly converted to Anarchism, Leftism, or to Communism, preferably Chinese".

[7] In 1966, Giannettini published with Pino Rauti "Red Hands on the Armed Forces" (Le mani rosse sulle forze armate).

[8] During this trip, the two men would meet the newly elected Chancellor Willy Brandt and his Defense Minister Helmut Schmidt at the Italian embassy.
