The U.S. must respond to China’s increasing aggression in the South China Sea.

I note this concern in light of what occurred on Sunday, when a Chinese warship sailed within 45 yards of the front of the USS Decatur, forcing it to change course to avoid a collision. This action occurred in international waters and was a wanton breach of international law. Indeed, it was an outrageous breach: The Spratly Islands chain where the incident occurred is 700 miles from Chinese soil.
