Whether you like them or dislike them, you just can't deny the fact that they are capable of making things happen.  As for Xi Jinping's policy regarding S China Sea, I wonder if it is the right course.  Most Asian countries might want to look up to China as their big brother not as their big bully.  If President Xi becomes too aggressive in his territorial claims, US will eventually proves its China Threat to be true or at least justify its China Threat Theory.
