Nogo was a featured speaker at May 2011 a rally in support of Ratko Mladić held in Banja Luka, Republika Srpska, Bosnia and Herzegovina, following the former Bosnian Serb military leader's arrest in Serbia on war crimes charges. Nogo was quoted as saying, "There are more Mladićs in Serbia, they grow and will continue where he stopped." Two years later, he announced that Dveri would seek to bring criminal charges against Serbian government representatives who negotiated the 2013 Brussels Agreement, which normalized some aspects of Serbia's relations with Kosovo.
