This article is an attempt to answer the questions that have long been bothering historians, political scientists, sociologists and lawyers, as well as ordinary people, nationals of the former anti-Hitler coalition and members of the fascist Berlin-Rome-Tokyo coalition: namely, who really won World War II and who lost the peace that put an end to the war in Europe and the world? Who had reasons to celebrate victory, and who suffered a bitter defeat and enslavement?
The main thesis of this article is the observation that, in military terms, World War II was won by the states belonging to the anti-fascist coalition, and lost by Germany, Italy, Japan and their allies. However, in political and economic terms, World War II was won by Western countries led by the United States, and lost by Central and Eastern European countries, with the Soviet Union at the forefront. In international terms, the war and peace were won primarily by the United States and the Soviet Union. These countries have become global superpowers that created a new international order, called the Yalta-Potsdam governance.
