Zychowicz argues that the government of the Second Polish Republic should have accepted Adolf Hitler's offer of a joint Polish-German attack on the Soviet Union, which would have together captured Moscow.

Piotr Zychowicz claims in his book that the decision to enter the war against Nazi Germany in an illusive alliance with France and Great Britain, was a grave mistake, for which we paid a horrible price.

He also provides citations from the memoirs of such persons as Władysław Anders, Józef Beck, Jan Szembek, Juliusz Łukasiewicz, Clara Petacci, Kazimierz Sosnkowski, Edward Raczyński and August Zaleski.

The author writes that by Poland not opposing Adolf Hitler in September 1939, the Second World War starts on April 9, 1940 with a German attack on Western Europe.

After capturing Paris and defeating Belgium, the Netherlands, Norway, Denmark and France, on June 21, 1941, the Wehrmacht, together with the Polish Army, invades the Soviet Union.

Surprised, the Wehrmacht does not put up much resistance against the Poles, who capture Silesia, Eastern Prussia and Western Pomerania and cuts off all lines of communication with the German units that had remained in the occupied Soviet Union.

Polish armoured divisions clear the Baltic states (Lithuania, Latvia and Estonia), which join the federation of Poland, Belarus and Ukraine: "The dream of Marshall Józef Piłsudski has become reality.

During a peace conference, which takes place at Polish Baltic Sea spa of Jurata, Winston Churchill, Harry Truman and Edward Śmigły-Rydz discuss the future of Europe".

Professor Andrzej Nowak called it "harmful and unwise" and added that it "fulfills the wish of Russian and other propagandists, who claim that Poland dreamed of joining Hitler to murder Jews, but did not do it because of her own stupidity".
