During the 1960s and 1970s, the Radical Left in Lebanon took shape through its critical stance towards the Lebanese Communist Party, the USSR, and pan-Arab movements, and was embedded in transnational protest networks. I propose to explore the modes of reference to Vietnam in order to deci- pher the interplay of tensions and convergences between the redefinition of strategic challenges and the reframing of a transnational universe of mea- ning, oriented by revolutionary hopes. I show how the multifarious references to this distant model are at play in both the transformations in the militant landscape and the reconfiguration of meanings and values.
