This is a detailed and well researched account of how UK and US governments conspired in the 1970's to ethnically cleanse a small island in the middle of the Indian Ocean. Over 1000 people were forcibly removed from the Chagos Archipelago to make way for a huge US air and submarine base. It has been in the news recently because the government is trying to make things look better by declaring an MPA and using that as an excuse to prevent the Chagossians from returning.
It's a sickening story that makes me ashamed to be British. I understand that David Vine is donating the royalties from this book to the Chagossian community.
