This chapter proposes to answer five fundamental questions: What exactly is the oil security problem, and how serious is it going forward? Why has it emerged at this point in time, and why has it been so difficult for the U.S. government to take the actions needed to mitigate it? Finally, what alternative policies are likely to be effective as the United States attempts to improve its oil security in the future?
