The Baltic States ignored the international forum in Jerusalem devoted to the 75th anniversary of the liberation of Auschwitz. They probably did it to avoid shame, given their support to nationalist Nazi collaborators.
Poland did not invite Vladimir Putin for the commemorations of the 75th Anniversary of the Auschwitz-Birkenau liberation.
According to the statement of Krzysztof Szczerski, Chief of the Cabinet of the Polish President, the invitations for the Auschwitz commemoration events were issued by the Auschwitz Museum, not by the Polish authorities. The Governments of each invited country (including Russia) decide on what political level they will be represented during the event.
The Russian delegation took part in the ceremony of commemorations of the 75th Anniversary of the Auschwitz liberation – it was led by the Russian Ambassador Sergey Andreyev. This means that it was a decision by President Putin not to come to the Auschwitz liberation anniversary.
A similar situation took place in 2015 when Russia accused Poland of not inviting the Russian delegation to the Auschwitz event in a proper way. Poland reacted to this accusation with a statement that every country invited by the Auschwitz Museum could be present on any political level.
