An ‘Irish Cuba’ – on Britain’s doorstep? This book studies perceptions of the Soviet Union's influence over Irish revolutionaries during the Cold War. The Dublin authorities did not allow the Irish state’s non-aligned status to prevent them joining the West’s struggle against communism. Leading officials, such as Colonel Dan Bryan in G2, the Irish army intelligence directorate, argued that Ireland should assist the NATO powers. British and Irish officials believed communists in Ireland were directed by the British communist party, the CPGB.
