According to his thought, Fascism had to return to its origins, that is to the revolutionary movement of 1919, ideally linked to the experience of the first squadristi and the Arditi of the Great War; "a more radical revolution combined with the recovery of a more fundamentalist tradition".

More than the political statements of the Sansepolcro manifesto, however, Giani exalted the struggle of young people against the bourgeoisie in the early postwar period; Fascist mysticism considered itself the representative of this youthful world inspired by the love of country, a guard of the permanent revolution in contrast with the opportunists and careerists.

[11][12][13][14] In 1939, after long pressuring by Giani, the official seat of the School of Fascist Mysticism moved to "Il Covo", with a ceremony presided over by the secretary of the PNF Achille Starace.

Over the years the "Covo" had been transformed into a permanent museum of the Fascist Revolution, and starting from 15 November 1939 the entire building had been proclaimed a "national monument" complete with an "honor guard" made of squadrists and war veterans.

Between 19 and 20 February 1940, on the occasion of the tenth anniversary of the school's foundation, Giani organized the "National Convention of Fascist Mystic" in Milan, which in his intentions should have been the first of the a series, but none followed due to Italy’s entry into World War II.

Finally, on 9 November 1940 he was able to leave for North Africa as war correspondent of Il Popolo d'Italia, Cronaca Prealpina and L'Illustrazione Italiana, attached to the units of the Regia Aeronautica.
