World War 2 was a series of regional conflicts that interacted strategically and politically. It included about 5 wars that involved small battles.
World War 2 allies were the United Kingdom and the United States. Japan and Germany were referred to as axis.
Even though each of the regional wars of WW2 began for different reasons it was believed that is occurred because of Axis aggression.
WW2 started on July 7th, 1937 when Japan invaded China although the U.S. joined the war when Japan attacked Pearl Harbor on December 7th 1941.
WW2 took place across the globe. Most of the violence and action took place in Europe, East Asia, and islands in the Pacific Ocean. Countries like Poland, China, Russia, and Germany were directly involved in war and suffered terribly
Some WW2 legacies still impact our lives today. The Japanese government still faces criticism to this day, while Nazi hunters continue to track down war criminals who were never brought to justice
