To the history of the question: why in the summer of 1941 Soviet Union did not dare to preemptive strike on Germany?

The study is devoted to consideration of falsification of events of one of difficult and confused pages of Great Patriotic War. The understatement, concealment or perversion of the truth about Great Patriotic War inevitably generates a set of myths forging history of Great Patriotic War which cor-nerstone is the thesis about equal responsibility of the USSR and Germany for the war initiation. As starting point of this concept the authors specify false ideas of Soviet system essence, aggressive by nature and Stalin regime. Proceeding from these representations, some authors develop the concepts which do not have even a little evidential documentary base, are content with generally open sources of agitation and propaganda character, mem-oirs literature of quite doubtful historical character. Using and analyzing the documents of military and political character of this problem is followed by ignorance or conscious concealing or distortion of real facts. Thus falsifi-ers do not hide the involvement, do not use documentary materials and pub-lished memoirs of direct participants of those events from German side con-tradicting their concept. Conducted research disproves false versions about aggression preparing by Soviet Union against Germany. They are con-structed on historic facts falsification, using documents of agitation and propaganda character and unreasonable "creativity" of some sources.
