A substantially revised edition of a collaborative work on Iran (reviewed in Foreign Affairs, Spring 1983). For a quick look at today's problems and policies, and particularly at the internal situation on which knowledge is scanty, this is an excellent handbook. The authors whose assignment was to cover international relations (Gary Sick, William Miller and Richard Cottam) are no more complimentary in their comments on American policy than is R. K. Ramazani in the work noted above-and this was before the arms sales revelations.
