Not a complete waste of time, but too much of this feels cobbled together from pamphlets and conference reports. The book is a mishmash of historical, sociological and political approaches to proliferation, most of which felt quite basic, although I suppose that's not a hugely fair criticism to make of a general introduction, and generally I feel I was introduced.
A lot of time is spent emphasising the role America could and should be playing in the non-proliferation community; when the book was written in 2006 I imagine this might have been intended as a call to arms against Bush's overt policy of counter-proliferation and regime change. However, the passing of the baton to Obama has coincided with a more nebulous rhetoric vis-a-vis US security and militarism, and most of Cirincone's criticisms are too specific to have lasting relevance, while being too narrow to function as a decent history of American foreign policy.
This is also true of the political analyses of N.Korea, Pakistan and Iran in my opinion, which never delve deep enough to be genuinely convincing. That said, I thought the explanation of why unsecured materials are a greater threat than 'rogue states' was eloquently put, and I found it reassuring to note the substantial progress made in non-proliferation over 60 years. It's good to know that there's more to nuclear diplomacy than brinkmanship, even if Cirincione's account of it is relatively slight.
