I read Kissinger’s book many years ago when I was still a run-of-the-mill conservative and liked it. I’m sure I’d evaluate it differently today.
Unfortunately, most of the foreign policy specialists out there who write books are Council-on-Foreign-Relations types. I’m not aware of a decent survey of modern diplomacy from a libertarian perspective. Pat Buchanan’s books (e.g. A Republic, Not an Empire) have a lot of good anti-imperial stuff in them. Also search the archives of publications like Left and Right or the daily articles on mises.org for info on specific events you might be interested in.
