The correct answer is Soviet Union
World War II, which took place between 1939 and 1945, left thousands of people dead, countless injured and redefined the balance of world power.
The main consequences of this conflict were the rise of the United States, the division of the world between capitalism and socialism and the rise of the UN.
The conflict, according to some estimates, caused the death of 45 million people and left 35 million injured. The largest number of victims was registered in the Soviet Union with 20 million deaths.
In Poland, 6 million casualties are estimated, while Germany accounts for 5.5 million. As a result of the conflict, 1.5 million Japanese people died.
In addition, World War II produced one of the most atrocious crimes against humanity: the murder of 6 million Jews on an industrial scale.
The physical elimination of these people was part of a project by Adolf Hitler (1889-1945), known as the Final Solution. To accomplish this, the Nazis devised a complex system of extermination in concentration camps and death camps.
