This groundbreaking study offers a genuinely multidisciplinary exploration of cultural influences on foreign policy. Through an innovative blend of historical analysis, neoclassical realist theory, and cultural studies, Amelia Hadfield-Amkhan shows how national identity has been a catalyst for British foreign policy decisions, helping the state to both define and defend itself. Representing key points of crisis, her case studies include the 1882 attempt to construct a tunnel to France, the 1982 Falklands War, and the 2003 decision to remain outside the Eurozone. The author argues that these events, marking the decline of a great power, have forced Britain into periods of deep self-reflection that are carved into its culture and etched into its policy stances on central issues of sovereignty, territorial integrity, international recognition, and even monetary policy.
