Reciprocation now key to Korean Peninsula peace

It is always good to hear Pyongyang vow to denuclearize. Even better when it comes with a timeline.

Such a dramatic turnaround will surely rekindle hopes after the United States president canceled a planned visit by his secretary of state to Pyongyang citing lack of progress.
