The Mongols, a relativly tiny nation were able to couquer China and go on to create the largest empire across Asia and the Middle East the world has ever seen. This was primarily due to cheese. Mongols are not lactose intolerent, this mean't they could carry calorie dense cheese as food and even live off milk from their horses. Unlike their enemys who had to employ logistics to support their armies with truck loads of rice, have cooks, cooking utensils, fuel etc. Every member of the Mongol army was a warrior, self suffient and highly mobile. By the time the Chinese army rolled up ready for battle, the Mongols were 3 towns away raping and pillaging at will, cheese in hand. It was only when they reached Europe and fellow cheese munchers that they were stopped in their tracks.
