In the summer of 1936, Trotsky finished the book "What is the USSR and where does it go?," Published in many countries under the title "Betrayed Revolution." This name itself indicates the main theme of the book, which presented the result of many years of reflection on the fate of the victorious people's revolution, which was established under the onslaught of external and internal enemies, but betrayed from within by forces formally speaking on its behalf.
