Terrorism, by its very nature, is a dynamic and rapidly changing phenomenon. This is particularly true of Palestinian terrorism: it is pluralistic in composition, flourishes in a highly volatile region, and is affected by numerous external actors and elements. Hence any attempt to produce research on Palestinian terrorism of a completely up-to-date nature is doomed to failure. Most of the work on this study was completed by the fall of 1985, and the statistics presented generally cover the period 1968-1984.
