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 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 todays ' sociaties so that WWII crimes would never repeat , stating that " unity and determination are the only true power against the new Aushwitz , Jasenovac , Ovčara and Srebrenica "
