Which of the following was not one of Joseph Stalin's ten blows during World War II?

The Vistula-Oder Offensive is not considered one of Joseph Stalin's ten major military operations during World War II. The main reason is that it was primarily conducted by the Soviet forces under Stalin's command, whereas the other major operations involved a collective effort of various Allied powers. While the Vistula-Oder Offensive was a significant military campaign in which the Soviet Union successfully advanced towards Germany, it was not specifically attributed to Stalin's strategic planning or recognized as a crucial blow against the Axis forces, unlike the other operations that were widely acknowledged for their impact on the outcome of the war.
