>Is war really about scarcity of resources or about conflict over resources, regardless of scarcity? I think there is a huge difference between the world before the green revolution and after, and I personally think that this difference is a big part of why we haven't seen major power wars after the middle of the 20th century. World war two was the last major power war, and it was also the last major power war fought when there were not enough calories for everyone to eat their fill. Coincidence? After world war two (well, after the 'green revolution' that happened in the mid 20th century) there was enough food, and... you could argue that we haven't had a direct major power war since then. I personally think that the fact that getting enough calories is generally not a problem anymore has a lot to do with the fact that we haven't seen any major power wars lately.
