If food and consumption are part of a nations identity, then could warfare be culturally determined as well? The short film that plays with this theme is called Food Fight by Stefan Nadelman: An abridged history of war, from World War II to present day, told through the foods of the countries in conflict. It's totally US centric and therefore historically inaccurate, but nonetheless great "fun" to digest.
Before the film was penned, I was imagining a history of ALL conflict. I quickly realized that it would not only take forever to do that, but I had no idea what ancient Egyptians where eating. So I narrowed the scope to American-centric conflict... with a dash of Israeli interest in there, from WWII on. From a production standpoint, these parameters seemed feasable. I kept it as simple as possible and in doing so, as many of you have pointed out, there are countries that don't get a proper say... and to that, I apologize.
