Book excerpt: This book, originally published in 1982, analyzes the process of radical foreign policy change – how states restructure their foreign relations, and why they do so. Using a common analystical framework, the authors examine Bhutan, Burma, Canada, Child, China and Tanzania. They distinguish between piecemeal foreign policy change and adaptation, and the fundamental re-ordering of foreign policy. Their analysis underlines the extent to which non-military and sometimes imagined threats, such as dependency and external economic and cultural penetration, can constitute an important cause of radical realignment activity.
