You are in no position to lecture anyone of civil discussion.
Read you last post boy. Who is everyone?
The world does not recognize PRC's claim and the only way to make it a legal dispute is either PRC lodge a claim to ICJ or seize it by military force closing any chance of the global society accepting PRC's claim.
From an Asian perspective, Japan has lost all respect. It has turned into a nation of whiners, turning to its master, the USA, at the sign of every little trouble, and always inviting Uncle Sam to poke its nose into East Asia. Japans double standard can be seen from its reluctance to join the AIIB, which would benefit all Asian nations. While Japan was a rich and developed country for a long time, it did very littel to help develop other Asian nations, which China is currently doing. It had been punching above its weight due to the sole support and unmitigated glorification from the West. Japan has become a number troublemaker in Asia and I hope it is put in its place, soon.
