I have asked before if anyone has read Michael Huemer's libertarian book, and aparently nobody has. (David Gordon told me over e-mail that he is planning to review it one day.) I still haven't had a chance to read it myself, but here is an article on Cato Unbound in which Huemer outlines basic points of his book:

(Warning: He does not use "NAP" or "property rights" anywhere. I know, the first one alone drops him a whole letter grade. I don't think he thinks NAP is a cohesive concept, but maybe he doesn't fully understand the way it's used by libertarians. But seriously, I think the fact that he does not define property rights makes his position weaker.)
His definition of terrorist should specify civilians imo.
