As India expands its strategic reach in the Indian Ocean, it will need friends that it can count on. The island state of Mauritius has long been one of India's closest allies in the region. This article discusses India's plans for a military intervention in Mauritius in 1983 to prevent a feared coup that may have threatened India's interests.
