Back Seat History Lesson

Seriously, what is this child reading? Conversation with my 6-yr-old on the way to the grocery store yesterday:

Youngest Weed: Mom, do you know who tried to defeat us in World War II?
Me: Who?
YW: Hitler, Benito Mussolini and the Empire of Japan
Me:  (!) /stifled laughter because he's so dang serious and also ever-so-slightly aspirates the "s" of Mussolini

Fearfully ignorant of Stalin, though.
