In May 2010, Josipović met the leaders of the Republika Srpska, Rajko Kuzmanović and Milorad Dodik, as well as the prominent Bosniak leader Sulejman Tihić, and visited the site of the Sijekovac killings to pay respect to the victims. The site and the visit provoked some controversy in the Croatian public, with allegations of impropriety levelled against President Josipović and the authorities of Republika Srpska for misattributing some of the casualties. During a visit to Israel in February 2012, Josipović apologized for atrocities committed against Jews by the Croatian Ustaše regime during the 1940s. Josipović's apology was accompanied by criticism in Croatia because his predecessor Stjepan Mesić had already apologized earlier for the crimes. Josipović also said that "he is the son of Tito's partisan". During a speech at the commemoration for the victims of the Jasenovac concentration camp in May 2014, Josipović described the crimes that happened in Jasenovac as genocide. During his speech, Josipović stressed that the vast majority of Croatian people fought against Ustasha policies during the Second World War by participating in an anti-fascist movement, urging everyone not to forget that "exclusivity, hatred and intolerance and the evils of fascism and other totalitarian ideologies" are still present in today's societies so that WWII crimes would never repeat, stating that "unity and determination are the only true power against the new Auschwitz, Jasenovac, Ovčara and Srebrenica".
