The history of the USSR's entry into World War II continues to be a "sore" topic for Russia. A striking example of this is the commercial success of the extremely tendentious book by V. Suvorov (Rezun) "Icebreaker." One of Suvorov's main opponents since the mid-80s is the author of this book, the famous historian Professor G. Gorodetsky, director of the Cummings Center for the Study of Russia and Eastern Europe at Tel Aviv University. Polemicizing with Suvorov, Gorodetsky on a huge factual material proves the inconsistency and provocativeness of Suvorov's versions.
