Vandals smeared swastikas and slogans comparing Prime Minister Ariel Sharon to Adolf Hitler on the Central Zionist Archives building on the road to Yad Vashem. "Sharon is following in Hitler's footsteps," said one slogan; another read, "Sharon, Hitler would have been proud of you." Police believe right-wing Jewish militants opposed to Sharon’s plan to pull out of the Gaza Strip this summer are responsible for the graffiti. Some Sharon opponents have compared his plan to evacuate 8,000 Gaza settlers from their homes to the “ethnic cleansing” carried out by the Nazis. Asked about the analogy, Sharon said: "Anyone who attempts to compare these things is making a serious mistake." Sharon made the remarks aboard a plane to Poland, where he attended the annual “March of the Living” between the Auschwitz and Birkenau death camps.
