"As the Ukraine crisis has intensified over the past six months, Russia has been developing a new form of warfare – inserting special forces, provoking, and slowly, deliberately escalating the conflict. Russian actions flout international law and the agreements that have assured stability in the post-cold war world. But warnings and sanctions have thus far failed. The Nato summit in Wales this week offers the best, and perhaps last, opportunity to halt aggression in Europe without major commitments of Nato forces. But to do so requires a deeper understanding of the situation and much more resolute allied action."
