I read Morris Morley and Chris McGillion's Reagan and Pinochet: The Struggle Over U.S. Policy Toward Chile (2015). I'm finishing up a review for Latin American Politics & Society. The upshot is that I enjoyed the book.
The book makes two main contributions. First, it explains why U.S. policy toward Chile evolved in ways that were not obvious when Reagan first took office, and how that was shaped by internal administration schisms. Second, it explores the difficulties and frustrations U.S. policy makers had influencing events in Chile.
It is based on extensive archival work and interviews, so it's a very nice insider view of the bureaucratic machinations going on. I actually found it more useful than the authors themselves give it (or seem to give it) credit for.
I don’t believe I’ve ever had reason to criticize academic authors for being too modest, yet that’s what I felt as I read. Morley and McGillion don’t situate themselves in any particular scholarly context. It is a bit frustrating that the introduction begins immediately with a chronological account of U.S. policy toward Latin America but does not first lay out the book’s key arguments, contribution and structure. In fact their foreign policy analysis is more useful than they even try to claim.
My full review will be much longer. I definitely recommend it.
