And Peron was a Marxist, no?
No, peron was more of a corporatist/caudillo. As I recall, although he was as much a socialist as anything at times, he was usually more of a corporatist (an essential economic element of fascism), but heavily nationalist at all times (another essential element of fascism), and always a populist. peron’s own example is part of what gives rise to the existence of a rightist Peronism, and a leftist Peronism.
