What we have been witnessing, in effect, is a reign of what Dr. Hans Blix called "ad hockery", wherein one or a handful of countries circumvent multilateral processes and laws to advance their own interests, and the expense of our international legal regime and the civilized society that such a law-based regime builds.

Ad hockery is the noun form of ad hoc, an adverb meaning "for the special purpose or end presently under consideration," translating literally from Latin as "for this." It entered English in the late 1800s.
