There is a very good discussion of Grand Strategy over at Democracy Arsenal. The best I think is this post by David Shorr (with links embedded in his to the other discussions) as he manages to “transclude” [transcend and include] the other thinkers in the bunch.
Shorr’s discussion of a rules-based international order jives well with Barnett’s work.
While it is currently a time of intellectual ferment on the (heterodox) right on a number of fronts, foreign policy is not one of them. For that, need to look to the liberals.
