China is a bicameral government and always has been. Civilian doesn’t hold the ultimate decision making power. It’s shared by civilian and army. The civilians didn’t come across the Yalu river 1 million men strong back during the rout of America back to the 38th parallel. The Chinese military did that. The Chinese military wants the weak water Obama administration out of their sphere of influence. North Korea is their mad dog. We will back down because Obama and his crew lack the balls to stand up for South Korea.
I can agree that PLA has the ultimate veto power and they are the one which is shaping China’s policy on NK.
