The 1959 Cuban Revolution was a major change and an axis of division between political forces. Joe Baxter was fascinated by the Cuban experience and its stand against the USA — which only became complete in 1961, when Fidel Castro announced his choice in favor of socialism. At that time, Alberto Ezcurra and his followers became serious opponents of the Cuban revolution. Furthermore, many activists struggled alongside the trade unions and associated themselves with the Peronist Youth (JP), which wasn’t well viewed in all sectors of the MNT. Thus, in March 1960, the priest Meinvielle, opposed to the alliance with Peronism, accused the original core of Marxist deviations. Meinvielle then created the Guardia Restauradora Nacionalista (GRN) which imposed the membership requirements of European ancestry and a family history of at least six generations of residence in Argentina.
