Another focus of Isac's political activity was mediating a Hungarian–Romanian reconciliation, both before and after the 1919 military conflict, while reaching out to both Hungarians in Hungary and the Hungarian community in Romania. As noted by literary historians John Neubauer and Marcel Cornis-Pope, Isac was one of the Romanian authors who could combine a nationalist outlook with respect for minority cultures: in his articles for the Bucharest-based "Ideea Europeană" magazine and the Hungarian "Napkelet" of Cluj, he demanded equal cultural rights for all of Greater Romania's communities. His call to the "great masses" of Romanians and Hungarians, read: "There is only one possible politics in Romania: the politics of true democracy. By its very nature such politics safeguards the rights of everybody, [including] Hungarians, who lead today an isolated life in Transylvania. [...] it is the duty of Romanian writers to initiate divorce proceedings from the negative traditions".
