Bosnian War believed Operation Storm lent their diplomatic mission a chance to succeed, reflecting the opinion of US President Bill Clinton that the Serbs would not negotiate seriously unless they sustained major military defeats. In Serbia, Milošević condemned the Croatian attack, but the Milošević-influenced press also denounced the leadership of the RSK as being incompetent, while the most extreme politicians, including Vojislav Šešelj, demanded retaliation against Croatia. Bosnian Serb leader Radovan Karadžić begged for the Yugoslav Army to help while accusing Milošević of treason. In Croatia, HV units returning to their bases were given heroes' welcomes in numerous cities, and a commemorative medal was created to be issued to HV troops who took part in the operation.
