The aim was also to prove that the "destruction of German fascism was not only the work of Army organizations, but that the role of partisans and resistance fighters were kept in good memory".

Also, as neo-Nazi graffiti 'became increasingly impertinent in Germany' and the desecration of the Cologne synagogue in December 1959, FIR suggested to convene an “International Conference against the resurgence of Nazism and anti-Semitism”.

Together with the International League for Human Rights, the Union of Israeli Jewish communities in Italy, the ANPPIA and ANED, FIR organized this conference in March 1960 in Florence, which was attended by 130 delegates from 13 countries.

A further step in the battle against the 'forces of the past' were found in the campaign against the HIAG (“Aid Society of former member of the Waffen-SS”), initiated by the FIR the International meeting against the re-emergence of Nazism and Fascism in October 1963 in Florence.

This was interpreted to mean to "disclose the historical truth about the resistance struggle, the reality of fascism and the role of the anti-Hitler coalition, the allied forces", "including the Soviet soldiers" who "bore the brunt of the war" – the destruction of the fascist barbarism".

Due to various activities and initiatives for disarmament and international cooperation, the Secretary General of the United Nations, on 15 September 1987, designated FIR as “Peace Messenger”.

The 27th Regular congress, hold in Prague on 18/19 November 2016, confirmed Vilmos Hanti in his role of President of the federation and elected Filippo Giuffrida Repaci, General Mikhail Moiseyev and Christos Tzintsilonis as Vicepresidents.
