Go to your library and borrow a copy of "American Caesar," a book about MacArthur's establishment of democracy in Japan. That book will no doubt have reference pages that will be of value to your young scholar. My high school US History book contained a political cartoon from that period depicting MacArthur as a baseball coach standing behind a Japanese batter and to the side of the Japanese catcher. The caption read "The object of the game is to hit the ball, not the players." If he could scan that cartoon into his project it would add value.
You're hired! LOL. The problem is we have to do this for free. :-)
great info, Thank You!
