“This time it could be big and convincing enough.”
Big and convincing enough to demonstrate a credible nuclear deterrent? Or big and convincing enough to force a S. Korean response?
People are getting tired of BS from NK and China. Few S. Koreans would pin hope on China's cooperation from now on. Most of them gave up. I am sure some in gov and big corporations would like to apologize for China, and they do have power. However, it can't stop the grassroot sentiment once it gets rolling.
