I happened to buy a used book online--a 1955 book by Donald Shea, The Calvo Clause, which examines the question of intervention (or, as Calvo argued, absence of intervention) for foreign investors in Latin America (or indeed anywhere).
So this book was published at a time when U.S. policy makers were in a clearly interventionist mood and the Cold War would rage on for several more decades. As it turns out, the particular copy I got was originally from the State Department library (even with a stamp indicating the book was first received 1955 or 1956, I can't quite tell which), then subsequently withdrawn. In the back there is a check-out slip well glued in, with no evidence that there was ever any other previous slip. It was checked out a grand total of one time.
So I guess nobody in the State Department was particularly interested in learning more about Latin American ideas of non-intervention.
