'Meyer, De Franco, and Otto show that the problem of warning needs to be conceptualized broadly and seen as part of an interactive foreign policy process, with important warners being not only government officials, but NGOs, the media, and informal advisors. The sophisticated analysis is supported by detailed case studies drawing on a wide variety of unusual sources, and the result is a book of great interest.' Robert Jervis, Adlai E.
