These were choppy political waters, but Mohamed bin Laden surfed them adroitly. He became the Saudi government’s preferred builder. At the same time, he did so much business with the United States that he retained an agent in New York. He built classified projects for the U.S. military, including air bases and garrisons around Saudi Arabia’s western coast. He sent his oldest son, Salem, to England for a Western education. Four other sons would go on to study civil engineering in the United States.
