We explore how World War II unfolded, with Nazi Germany's aggressive expansion across Europe, leading to the occupation of several countries. From the invasion of Poland in 1939 to the Battle of Stalingrad in 1942-43, we examine the real-life events that shaped the course of the war. #MrEarth #ww2 #countryballs #animation #history #countryball #polandball #worldwarii #worldwar #wwii #operationbarbarossa #callofwar #germany #stalin #sovietunion #ussr #battles #invasion #russia #easternfront #history #worldhistory #europe #SolarBalls #Moon #Sun #Education #Educational
