The book deserves attention from readers interested in maritime affairs, who may be particularly interested in the sheer length of historical concern over the canal’s functionality and vulnerability; in the history of technology, particularly of high modernism, technological mega-projects, and the history of failure; and in the growth of environmental lobbying, the ecological sciences, and their interactions with government. It also provides a fascinating angle on American political involvement in the isthmus, especially from the 1940s through the 1970s.
