Only time will tell. In Europe, World War 2 is considered to have begun on September 1, 1939, with the Nazi German invasion of Poland. In 1940 Nazi Germany invaded and occupied most of France. Eventually the Germans occupied most of Europe. In 1941, Hitler abrogated his treaty with Stalin by invading the Soviet Union.
Historians do not agree on the exact date when World War II began. Most consider the German invasion of Poland on September 1, 1939, to be the beginning of the war. Others say it started when the Japanese invaded Manchuria on September 18, 1931. Others even regard World War I, which culminated in the Peace with the Central Powers in 1921 and World War II as parts of the same conflict, with only a breathing spell in between.
