This essay investigates the development of political, institutional and personal relations between the representatives of the French Parti Socialiste Unifié and Israel (with specific reference to Mapam) between 1960 and 1974. The author traces back to the Third-Worldist ideology the paradigm according to which the French party defined its own action at the international level and framed global phenomena, specifically the Arab-Israeli conflict. The essay reappraises the analysis proposed by the Psu in historical perspective, the changes within its political leadership and the effects of major global events on the definition of the party’s international relations with Israel. The essay describes the path made by the party in three different periods, which determined the passage of the Psu from an open supporter of the Zionist perspectives to a promoter of the Palestinian national cause, tracing the reasons for this passage in the dichotomous definition of international politics promoted by the Third-Worldist interpretation paradigm. The proposed analysis makes use of documentary material found mainly in the Psu collection in the French national archive of Pierrefitte-sur-Seine, the articles published in the Psu weekly Tribune Socialiste and the Cercle Bernard Lazare magazine, the Cahiers Bernard Lazare.
