The article is really, and more importantly, about Hersh's revelations with regard to the secretive Catholic order called the "Knights of Malta". From time to time I've run across references to this organization, usually with connotations about conspiracies, and I've never known what to make of such comments.
The author starts with Hersh's revelations and adds information from a variety of other sources. Hence, I found this article very useful in shedding some light on this secret organization, and its associated charity called "AmeriCares". Phelan writes:
Nowhere was the alliance between the Knights of Malta, AmeriCares and U.S. Intelligence more pervasive and troubling than in Central America.
