Did WWII start before Pearl Harbor was attacked or after?
You probably have all the information you need; you just need to take another look at it. The Japanese attack on Pearl Harbor led the United States to join the fighting in World War II. The war had already been raging in Europe and Asia for quite some time before U.S. troops got involved. Take a couple of minutes to re-read your source material about the Pearl Harbor bombing attack. You’ll see it doesn’t say that’s what started World War II. It says the war was already going on, and the Japanese attack is what got the U.S. into the war.
