In a recent discussion, the subject of Japans reason for not invading continental US was due to in part to US citizens being armed was brought up. I thought that it was mentioned in a WWII book. A quote by a member of the Japanese command?
I heard that the Battle of Midway was the battle that stopped the Japanese from attacking U.S. mainland. Their plans were to conquer Midway and Hawaii first and then proceed to U.S. mainland but due to their defeat in Midway those plans were stopped.
