As you said, the SoP can support giving aid to both Contras and Solidarity types of organisations. In short, the PNAC SoP is perfect marketspeak bafflegab; it sounds nice without actually saying very much, beyond the fact that the US needs to have a foreign policy.

Well, duh.

The question is, what shall that policy be based on? What are the base principles upon which policy shall be formulated? That's the real question, and one that's not answered anywhere. To get a handle on that, you have to go trolling through the various papers available on the website.
