When I heard the president of Iran, Mahmoud Ahmadinejad, declare that the Holocaust was a "myth," I couldn't help asking myself: "I wonder if the president of Iran would be talking this way if the price of oil were $20 a barrel today rather than $60 a barrel."

When I heard Venezuela's President Hugo Chavez telling British Prime Minister Tony Blair to "go right to hell" and telling his supporters that the U.S.-sponsored Free Trade Area of the Americas "can go to hell," too, I couldn't help saying to myself, "I wonder if the president of Venezuela would be saying all these things if the price of oil today were $20 a barrel rather than $60 a barrel, and his country had to make a living by empowering its own entrepreneurs, not just drilling wells."

As I followed events in the Persian Gulf during the past few years, I noticed that the first Arab Gulf state to hold a free and fair election, in which women could run and vote, and the first Arab Gulf state to undertake a total overhaul of its labor laws to make its own people more employable and less dependent on imported labor, was Bahrain. Bahrain happened to be the first Arab Gulf state expected to run out of oil. I couldn't help asking myself: "Could that all just be a coincidence?

The more I pondered these questions, the more it seemed obvious to me that there must be a correlation — a literal correlation that could be measured and graphed — between the price of oil and the pace, scope and sustainability of political freedoms and economic reforms in certain countries.

I would be the first to acknowledge that this is not a scientific lab experiment, because the rise and fall of economic and political freedom in a society can never be perfectly quantifiable or interchangeable. But I think there is value in trying to demonstrate this very real correlation between the price of oil and the pace of freedom, even with its imperfections.

The First Law of Petropolitics posits the following: The price of oil and the pace of freedom always move in opposite directions in oil-rich petrolist states. According to the First Law of Petropolitics, the higher the average global crude oil price rises, the more free speech, free press, free and fair elections, an independent judiciary, the rule of law and independent political parties are eroded. And these negative trends are reinforced by the fact that the higher the price goes, the less petrolist leaders are sensitive to what the world thinks or says about them.
