"This brilliant book should be of wide interest to students of government, politics, sociology, and law, as well as to high-level policy makers and the general public concerned with nuclear nonproliferation and problems of global governance. Mallard draws deftly on a wealth of primary and secondary sources to provide us with a lucid and captivating account of the centrality of 'opacity' as a discursive strategy in transnational affairs." (Daniel Halberstam, University of Michigan)"
