This book throws new light onto the 1963-66 period confrontation between Malaysia and Indonesia. The Brunei revolt in December 1962 started Confrontation but who started the Brunei revolt? Most historical accounts still hold A.M. Azahari of Brunei as culpable, but this book vindicates his role: Roy Henry (from British intelligence) openly admitted responsibility for starting the Brunei Revolt.

This is but one result of accessing recently-released archival material and interviewing many former officials (some of whom are featured in the archival material). Documents which no previous works have accessed helped Dr Poulgrain piece together the genesis of Konfrontasi.

An American-British group called SIFE (Security Intelligence Far East) was the key to Konfrontasi. The British kept control of Brunei oil, even at the cost of manipulating the Sultanate; and in Singapore, they actively promoted Lee Kuan Yew; but in Indonesia, beyond the joint strategi of ousting Sukarno, the British and Americans were actually rivals.

This book looks into the vectors that generated Konfrontasi in early 1963, rather than the attempted solution (publication forthcoming) by President Kennedy in late 1963.
