When originally published in 1981 this was the first book to bring together in one volume some of the most thoughtful work by British academics and specialists studying the political violence and terrorism which had recently challenged Britain and other Western democracies. Four chapters consider the strategy and tactics of the IRA and the problems of the Northern Ireland conflict. Other articles discuss the phenomena of international terrorism. Essential reading for courses on political violence, revolution war and staregic studies, this volume will also be of relevance for training course in military and police staff colleges.
