Robert Green served for twenty years in the Royal Navy from 1962-82. As a Fleet Air Arm observer/bomardier-navigator, he flew in Buccaneer nuclear strike aircraft and anti-submarine helicopters. Commander Green's final appointment was as Staff Officer (Intelligence) to the Commander-in-Chief Fleet. He took voluntary redundancy in 1981 and was released after the 1982 Falklands War. The 1984 murder of his aunt Hilda Murrell led him to examine and then challenge the hazards of nuclear electricity generation - and nuclear weapons. He is now co-director, with his wife Dr Kate Dewes ONZM, of the Disarmament & Security Centre in New Zealand. His previous book, Security Without Nuclear Deterrence, was published in 2010.
