Joe Biden is in Serbia at the moment, offering friendly noises about “mutual respect” and agreeing to disagree over the Kosovo question. His warmness is not entirely reciprocated. “Biden, you Nazi scum, go home,” ordered a poster from the Radical Party. “We believe that the statements and policies of Joseph Biden are contrary to the interests of Serbia and the Serbian people,” said Jovan Palalic, of the Serbian Democratic Party. Another politician, Aleksandar Vulin, added that Biden “is not welcome in Serbia.” Most reports have marginalized Biden’s critics as “nationalists.” But can one entirely blame some Serbs — “nationalist” or not — for resenting Biden? He was, after all, instrumental in ramping up Bill Clinton’s aggression towards them in 1995. As Chairman of the Senate Foreign Relations Committee, his advocacy of a “lift and strike” resolution encouraged Clinton to initiate the NATO bombing campaign, which killed so many Serb civilians.
