The 31st anniversary commemoration of “Operation Storm” in Knin, Croatia, on August 5th, was marred by disturbing displays of hate speech and threats of violence. Reports indicate attendees chanted Ustaše songs – associated with the fascist ideology of WWII – and issued calls for violence against Serbs and Serbia. These expressions fueled tensions and sparked condemnation, raising concerns about the resurgence of nationalist sentiment. The event highlighted deep-seated animosity stemming from the 1995 military operation which resulted in the expulsion of a large Serbian population from Croatia. Authorities have yet to comment extensively on the incidents, prompting criticism from regional observers. This display undermines efforts towards reconciliation and peaceful coexistence in the Balkans, raising fears of renewed ethnic conflict. The incident underscores the importance of addressing historical grievances and fostering inclusivity.
