Indeed, this time Japan is playing the role of a trouble maker. Japan is hellbent on how to manufacture a military conflict between China and USA. If Japan continues this, no sympathy for them.
If China really has to engage USA in war because of Japan, China must make sure that Japan does not exist at all. No matter whoever wins, China or USA, trouble maker Japan must pay the ultimate price.
Japan has over 100 active volcanoes which account for 10% of world's all the active volcanoes. One has to figure out ways of how to destabilize the junction of the 4 continental plates Japan is located at. A slight shift will make all the volcanoes erupt furiously and simultaneously. All the flora and fauna of Japan will be roasted first and then their ashes will be washed away by gigantic Tsunami waves. Japan will be a mere history.
