Answer 2

Oil is Power!” I don’t just mean power as in “energy,” I mean power, as in being a primary factor in the process of asserting and maintaining political dominance and control. Oil is needed to grow food, build infrastructure, advance technology, manufacture goods and transport them to market. It lubricates the mechanisms of both national and international politics. Those who can consistently get their hands on the most oil, at the best prices … will rule!

So what makes oil so highly valuable that individuals, companies and sovereign states would actually be willing to go to war, if necessary, in order to defend or fight to win their “beloved?”

First, “Oil is Universal!” It is a staple of our very existence! Oil plays a major role in practically every aspect of our lives from technology and transportation to the very food and business necessary for our survival.
