World War II in HD

World War II (1939–1945) was a global conflict involving major powers divided mainly between the Allies (including the U.S., Soviet Union, UK) and the Axis (Germany, Japan, Italy). It originated from unresolved issues of World War I, aggressive expansion, and totalitarian regimes. The war saw devastating battles, Holocaust atrocities, and widespread destruction. It ended with the unconditional surrender of Axis powers, leading to the occupation and reconstruction of defeated nations. The conflict reshaped the world order, led to the United Nations' formation, and marked a pivotal moment in 20th-century history, emphasizing the importance of international cooperation to prevent future wars.
