It is not my opinion it is the way things are. China has been always reactionary. It is in the DNA of the civilization. As long as Taiwan does not loss its mind and declare independence (or decides to have THAADs and American forces on her against Mainland) there is no way China will attack.Well, that's a very weak argument. People can dispute your argument without even rebuking your statement.
They will just say: "Sure, but today's China is fundamentally a different beast from that traditional China of 2000 years.", and you will have nothing to counter that.
