Here, Herblock ties oil to the Iranian hostage crisis. On November 4, 1979, an Iranian mob breached security at the American Embassy in Tehran and held sixty-six people, who quickly became known as “the hostages.” At the beginning of their 444-day imprisonment, President Carter’s administration halted Iranian oil imports, which prompted the Revolutionary Council of Iran to ban oil imports to America. Herblock later wrote, “the United States itself became hostage to the Iranian situation.”
