Amazon.com description: Product Description: Irish diplomats spied for the United States during the course of the war. Irish diplomats in Europe carried messages and supplied information to the OSS the predecessor of the CIA with the full knowledge and consent of de Valera. Behind the Green Curtain is a comprehensive account of Irish neutrality, focusing strongly on the American and to a lesser extent the Canadian connection. It confirms beyond any doubt that Ireland made a positive and partisan contribution to the allied war effort. Neutrality has become a shibboleth of modern Irish politics. Behind the Green Curtain explodes the myth behind that shibboleth in the most decisive way. From the reviews: Excellent and probably definitive account of Irish neutrality during the Second World War. Kevin Myers, Irish Independent With his brilliantly researched book, Dwyer confirms his status as a walking encyclopedia of Irish history as a work of scholarship, Behind the Green Curtain is nothing less than superb.
