During the early Cold War, Great Britain supplied heavy weaponry to neutral Switzerland. The relationship between the two countries is analyzed from 1945 to 1958, focusing on arms transfers, neutrality, and Britain's role. The research uncovers unique aspects of the Anglo-Swiss relationship, explores the reasons for Switzerland's weapons purchases and Britain's arms sales, reveals insights into the Cold War arms transfer system, and questions the sustainability of neutrality during the East-West conflict. The study sheds new light on the motivations of the countries involved and challenges the idea of neutrality in the face of the Cold War, as well as Britain's role as a western neutral and small power.
