"Atlantis Lost is a painstakingly researched and balanced book that reaches a number of thought-provoking conclusions."
— Presidential Studies Quarterly
“Throughout, Reyn’s focus is on writing a detailed history of these various issues. But it would be wrong to think that he has produced merely a dry, traditional diplomatic history. […] The result is an impressive level of complexity, out of which Reyn draws two sets of conclusions. At the end of the book, Reyn points to his grand themes: the clash between de Gaulle’s conservatism and the generally liberal America of the 1960s; the lack of leverage of even such a powerful hegemon as the United States in this period; the fact that, while de Gaulle shifted European perceptions of America, his actions also altered the American view of the ‘Old World’, particularly by shattering the pre-1963 Atlanticist vision. But, at a more detailed level, Reyn also adds much to the literature. For instance, he reinforces the growing consensus that the private Kennedy was far more pragmatic than his lofty rhetoric suggested, and that Johnson was a savvier diplomatic tactician than was once thought. Or, to take another example, by exploring the differences between policies and day-to-day interactions on the one hand, and the clashing viewpoints within various administrations on the other, Reyn also sheds important light on how, for instance, the low-level anti-Gaullism of State Department officials during the Kennedy years made it difficult for the president to pursue his grand design.
Overall, this is an excellent study which deserves to be read by anyone with an interest in US foreign policy of the period.”
