 During an award ceremony for Imre Kertész, Soros said that the victims of violence and abuse were becoming "perpetrators of violence", suggesting that this model explained Israel's behavior towards the Palestinians, which led to walkouts and Soros being booed.In July 2017, a Hungarian billboard campaign backed by Prime Minister Viktor Orbán, which was considered to be anti-semitic by the country's Jewish groups, vilified Soros as an enemy of the state, using the slogan "Let's not allow Soros to have the last laugh".The campaign was estimated to have cost 5.7bn forints (then US$21 million).
