Via Mark Safranski at Zenpundit - Disputing Global Dystopia: Phillips on "Our Dark Age Future".
... I am sympathetic to Col. Phillips' criticisms of the overly abstract and detached nature of IR in regard to the nature of international law and sovereignty. You can certainly see that "arid" and "imperialistic" attitude in many academics and NGO activists who like to present their novel theories and interpretations as "international law" when they lack any historical basis whatsoever (and are usually gamed to be highly restrictive on the authority of Western sovereign states to use force and permissive/exculpatory of the actions of Marxist/radical/Islamist terrorists or insurgents). Much of Phillips' condemnation of IR smacking of unreality from a practitioner's perspective is spot on.
That said, while definitely fuzzy and spottily adhered to in practice international law is not entirely "illusory", nor is it a byproduct of 20th century Wilsonian American exceptionalism as Phillips argued. Perhaps Hugo Grotius rings a bell? Or Alberico Gentili? Or the long history of admirality courts? Like common law or an unwritten tribal code, international law has evolved over a very long period of time and does exert some constraint upon the behavior of sovereigns. Statesmen and diplomats think about policy in terms of the impression it will make on other sovereigns, and international law is one of the yardsticks they contemplate. Admittedly, at times the constraint of international law is quite feeble but in other contexts it is strong. An American military officer, who can see firsthand the effect of creeping JAG lawyerism on command decisions on the battlefield ( in my view, greatly excessive and harmful ) and in the drafting of byzantine ROE, should know better than to make such a silly statement...
