The Calculus of Intelligence Cooperation, Richelson, International Journal of Intelligence and Counterintelligence, vol 4, no 3 (Fall 1990).
Author elaborates on the types of intelligence cooperation, the benefits and the costs. He mentions well-known agreements and pacts between UK, USA, Australian and other Western agencies, but also lesser known relationships between Israeli, Turkish and Iranian intelligence, various Eastern Bloc networks and the influential position of South Africa. However in 17 pages Richelson cannot discuss all the information now available.
