I've Have Gained Nothing From This
I appreciate the point that you're trying to make with this cartoon but I'm afraid your view of world history may be a little on the simplistic side. I don't know if I can think of any war that was fought merely because two people/nations had a disagreement over something-- certainly not World War 2 as you pointed out in your comments.
Apart from that, you yourself pointed out that this isn't the complete version of your film, and the link you provided to youtube does not function (although I'm not sure we should be grading you based on something we've seen on an outside site).
