This was a long and detailed report but I found no link with oil and speed limits. What I did find was a link with U.S. weapons manufacturers and wars around the globe. However, I also did some research and found something else. I am a believer in people's increasing need for dwindling resources can and does foster violence. I have been watching the scene in Yemen for a number of years and it is not good. One of the first things I do when looking at a countries problems is look up their demographics specifically their fertility rates and population density. Yemen is one of those countries whose population has been exploding with seemingly no end in sight. Push has come to shove, as it usually does and the result is war, violence and death. There is little any country can do in these cases and many take a side that provides the most profit. Now wars become global with each region fighting other regions and the country in which the problems started is caught in the middle. This is the world today.
