This book, first published in 1986, is a major study of semialignment and a review of the individual nations within NATO to which the model could be applied. Towards the end of the Cold War, there arose within NATO this intermediate category between alignment and nonalignment, whereby a member state enjoyed the status and facilities of NATO membership while disassociating itself from certain NATO programmes. This book analyses the phenomenon, and the possibility that it weakened the credibility of NATO deterrence and the defence posture versus the Soviet Union.
