Ang describes the development of the Five Power Defence Arrangements (FPDA), an important security regional arrangement, from its inception to the present from the perspectives of the five FPDA allies. The book recounts the establishment of the FPDA in 1971 from the Anglo-Malaysian Defence Agreement and its development in the first 20 years to the end of the Cold War in 1990. Based on declassified archival documents and secondary literature, it explores how the FDPA has evolved and adapted to provide different benefits to each of its partners after the Cold War. Ang contextualises the FPDA within existing scholarship and offers a glimpse into possible future trajectories. A valuable resource for scholars, students, researchers, and professionals interested in international history, defence, and security.
