If the reports are true that Prime Minister Benjamin Netanyahu intends on expressing support for the campaign that Russian President Vladimir Putin is conducting against Poland over the past few months, then it is a bad joke at the expense of the victims of the Holocaust, and its survivors, in whose name world leaders are gathering on Thursday at the Yad Vashem Holocaust memorial center in Jerusalem. At the center of Putin’s campaign is the accusation that Poland caused the outbreak of World War II, while minimizing the large role played by the Soviet Union.
