 In early 1943, while in Buchenwald, Trifa was among the prominent Legionnaires who agreed to disavow Sima's policies (the group also included Vasile Iasinschi, Ilie Gârneaţă, Constantin Popovici, Dumitru Grozea, and Corneliu Georgescu).According to historian Radu Ioanid, this move was mediated by German officials, who hoped to obtain a reconciliation between Antonescu and the Iron Guard.Ioanid, who described the Legionnaires' internment as a "bearable regime" in comparison to that of other prisoners in the same camps, noted that they were visited by high-ranking Nazi officials who warned them not to engage in any political activity.
