"This is an excellent book. It studies the global role of former leaders, frames it within the broader setting of the shifting nature of global governance, and elucidates its many dimensions with great verve and gusto. In shifting from the general to the particular (with its detailed, mini-portraits of individual leaders) Cooper makes the narrative come alive. The book makes an important contribution to the literature on diplomacy and IR more generally."Jorge Heine, Wilfrid Laurier University"Cooper superbly uncovers the emerging phenomenon of life-after-politics for policy entrepreneurs with global celebrity status, a phenomenon about which the rest of us are only superficially aware. He both explains and conceptualizes the trend, carefully scrutinizing its limits and opportunities for global governance."Geoffrey Wiseman, University of Southern California
