In the years since, I have of course realised, that perhaps it wasn't the most useful course of study to take (but I sure am glad I've got the piece of paper!), and this has just been reinforced by the following video. Much of what I studied, funnily enough, was how different players interact with each other, of which war has been a common thread.
So I give you: the history of modern warfare illustrated by food. It all makes sense now...If you need some help figuring out which country each food represents, check the cheat sheet.
