In the political circles of European countries attempts to reformat the history of World War II has been continuing. Poland is particularly active; there at the official level, as well as in the articles and in the speeches of politicians, political scientists and historians crude attacks against Russia for its commitment to objective assessments of the military past are allowed. Though, as the authors of this article mention, Russian politicians have not always been consistent in evaluation of Soviet-Polish relationships, hoping to reach a certain compromise. If there were any objections, they were mostly unconvincing. Obviously, as the article points, some statements and speeches are not without emotional colouring that is characteristic, when expressing mutual claims. However, the deliberate falsification of historical facts and evidence, from whatever side it occurs, does not meet the interests of the Polish and Russian peoples, in whose memory the heroes of the Red Army and the Polish Resistance have lived and will live. The authors point in the conclusions that it is hard to achieve mutual respect to key problems of World War II because of the overlay of the 18th – 19th centuries, connected with the “partitions of Poland”, the existence of the “Kingdom of Poland” as part of the Russian Empire, Soviet-Polish War of 1920. There can be only one way out, as many Russian and Polish scientists believe – to understand the complex twists and turns of Russo-Polish history, relying on the documents. Otherwise, the number of pseudoscientific, dishonest interpretations will grow.
