What statement about world war 2 is not true?

A common misconception about World War II is that it began on December 7, 1941, with the attack on Pearl Harbor. In reality, the war in Europe started earlier, on September 1, 1939, when Germany invaded Poland. The conflict expanded globally after the U.S. entered the war following the attack on Pearl Harbor, but the war had already been underway for over two years by that point.
