At least since 2003 and Tony Blair’s decision to join the Bush administration in the invasion of Iraq, agreement with US international agendas and decisions has been the guiding light of British foreign and security policy. This has been true even when these decisions have clearly contradicted Britain’s own interests, and to an extent that earlier British leaders (including even Margaret Thatcher) would have found unacceptable. To unpick the reasons for this subservience, and explore key aspects of the US hegemony that Britain serves, Anatol Lieven, director of the Eurasia Program at the Quincy Institute, is joined by Tom Stevenson, author of Someone Else’s Empire: British Illusions and American Hegemony (Verso 2023).
