This book examines little-known facts of cooperation of the USSR with many states, peoples and national liberation movements during the Second World War. The important role of many states, including small European countries, in countering Nazi aggression against the USSR and a number of other countries, in strengthening the military-political and economic positions of the Soviet Union, as well as the entire anti-fascist coalition in different regions of the world, is shown. In addition, it tells about the forgotten anti-Nazi resistance in a number of countries - allies of Germany. Of particular interest is the description of the attitude of some politicians and cultural figures to the personality of Stalin.
