Sixty years after his death, the life and thought of the economist, John Maynard Keynes, continues to be a subject of the greatest interest to scholars. Yet one of the most significant areas of Keynes' thinking has been strangely overlooked - international relations, a subject that was always of central importance to him. The purpose of this book is to explore comprehensively, for the first time, the evolution of Keynes' thinking on international relations , and to show how this is linked to the changing of his opinions on economic matters, in a way which deepens our understanding of both.
