WORLD WAR II – the largest war in the history of mankind, which started in 1939 with the German attack on Poland. 61 states with a population of 1.7 billion people were drawn into the war. Military operations were conducted on the territory of 40 states, as well as in sea and ocean theaters. The total losses of this war amounted to approximately 70 million people (including civilians), and economic damage is estimated at $ 2.6 trillion (the total cost of the war is about $ 4 trillion). The war ended in Europe with the unconditional surrender of Germany in May 1945, and in the Asia-Pacific region with the unconditional surrender of Japan in September 1945. The main losses in this war were suffered by the USSR, China, Germany, Japan and France. The main contribution to the victory over German Nazism and Japanese militarism was brought by the countries of the anti-Hitler coalition (the Allies of World War II) - the USSR, United Kingdom, the US, and partly France.
