This study is an attempt to examine two essential features of the ‎ guerrilla movement, its credibility and its effectiveness. In ‎ investigating these aspects, the author touches upon closely ‎ related problems, such as those of strategy, information and ‎ communication, people's war, and of conditions of political ‎ settlement and peace. The author tried to confine himself to the ‎ point of view of the guerrillas and to convey the ideas and ‎ expectations of various spokesmen and analysts of the two ‎ dominant guerrilla organizations, Fateh and the Popular Front for ‎ the Liberation of Palestine.‎
