Regarding the Nov. 26 editorial “Air control”:

Tension over the East China Sea has reached a new level, and the risk of miscalculation or a shooting incident is increasing. That would imperil not just China and Japan but also the region’s peace and its momentous economic advances.

This is a matter of immense concern for the United States and the rest of the world. So who can speak out against this unfolding madness? Superficially, the islands’ sovereignty dispute is among China, Japan and Taiwan. But the United States has a return-to-Asia strategy. The Obama administration has a duty to warn China and Japan before it is too late.
