Question

write about WW2 briefly

Answer 1

World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's countries —including all of the great powers —eventually forming two opposing military alliances : the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort , erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centers  (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki ), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict   in human history.

The World War ll ended in the Summer of 1945. It is estimated that more than 50 million people lost their lives during World War ll.
