In the book, "Confessions of an Economic Hitman", How did the OPEC Oil Embargo of 1973 change the way the U.S. government does business in the Middle East? What were the goals and strategies used to ensure that an event like the embargo would never happen again? Explain in detail the arrangement that our government struck with Saudi Arabia to secure U.S. national interests. Also, explain how this deal with Saudi Arabia differs from the triangle schemes used for poorer nations who aren’t rich and powerful like Saudi Arabia?
