A series of recent blunt statements from U.S. officials have left no doubt that Washington blames China's maritime expansionism for rising tensions in Asia. Now, America's main ally in the region needs to hear a similarly forthright message.
Japan had been clamoring for the U.S. to speak out more forcefully after China imposed an "air-defense identification zone" over a set of islands claimed by both countries. Officials in Tokyo have warned that any hint of daylight between Americans and Japanese only encourages further bullying from the mainland. For that same reason, U.S. officials have tempered their criticism of statements and actions by Japanese leaders that irk China, not to mention other victims of Japanese aggression during World War II.
