Important legal scholars have launched assaults against both the consequence and legitimacy of international law. These challenges are useful by way of testing international law's theoretical underpinnings, which, in the modern period at least, have never been very secure. With THE LIMITS OF INTERNATIONAL LAW, Jack Goldsmith and Eric Posner have done a service to those who put more faith in international law as a meaningful quantity. Especially in these the field's early renaissance years, understandings of international law should be considerably strengthened by the attack. Though I doubt the authors would thus conceive of their project, THE LIMITS OF INTERNATIONAL LAW may ultimately serve the object of their skepticism.
