Dissecting the Project for the New American Century

What is this project, why is it significant, and why aren't its connections to the current Administration more widely known?

The Project for the New American Century (PNAC) describes itself on it’s website as “a non-profit educational organization dedicated to a few fundamental propositions”, and “American leadership is good both for America and for the world; and that such leadership requires military strength, diplomatic energy and commitment to moral principle.” This description is interesting and somewhat misleading for a few reasons. If it’s non-profit how does it get it’s funding, what does American leadership mean, and what moral principles is it committed to?
