Well, I’ve seen a few “Janet and John” style depictions of just how the Second World War came about, but none quite so simplistic as this. Japan starts it all off with it’s invasion of Manchuria, then Italy invades Ethiopia and, finally, Hitler takes Austria and the Sudetenland - all with overwhelming force and little resistance either locally or internationally. Perhaps it was aimed at American children, as the animation is almost as rudimentary as the history, but if you’re looking for detail then you’re going to be disappointed.
