Russia should be ashamed to even make these requests after its clear hostile actions towards Israel supporting terrorist groups and Iran on the Northern Borders.

than Poland ever did to help liberate Jews from Nazi atrocity.

From Wikipedia:

In 1948 Pechersky was arrested by the Soviet authorities along with his brother during the countrywide Rootless cosmopolitan campaign against the Jews suspected of pro-Western leanings. Only after Stalin's death in 1953 was he released from jail due in part to mounting international pressure.[2] However, the harassment did not stop there. Pechersky was prevented by the Soviet government from testifying in multiple international trials related to Sobibor, including theEichmann Trial in Israel.[3] The last time he was refused the permission to exit the country and testify was in 1987, for a trial in Poland.

Such horrific place like Sovivor should be a place of reconciliation between the nations. We the yesterday's next generations have the duty to show maximum respect to the victims. That utmost respect implies that any nation that want to express tribute to the murdered should be allowed to do so. The Polish are playing politics in a place that should be above politics. This Polish cynical behavior disrespects many tens of thousands of members of my nation who lost their lives in that cursed inferno. I hope that my country - Israel - will insist that Russian representatives participate in the memorial. They are more than welcome. Especially as a nation that contributed so much to the defeat of fascism in Europe.
