UK-US intelligence and the wider Five Eyes community of Canada, Australia and New Zealand is primarily about one main thing, relationships. In this remarkable book, Anthony Wells charts fifty years of change, turmoil, intense challenges, successes and failures, and never-ending abiding UK-US and Five Eyes relationships. He traces the development of institutions that he firmly believes have sustained and indeed may have saved the free world, Western democracies and their allies from those ill disposed to the value system and culture of our nations. More than a chronology of the UK-US intelligence community during this fifty-year period, it is also a personal insight into key relationships and how the abiding strength of the US and the UK and its Five Eyes allies relationships. The author has relied on his own extensive unclassified collection of papers, personal notes, diaries, as well as his family library for source material to create this book.
