If there was a U.S.-China military conflict, America could easily attack China’s vital coastal regions. China would find it extremely difficult to break through American and Japanese missile defenses.
Every time China's diplomatic standing with its neighbors improves, the United States reappears to manufacture what it deems to be a suitable amount of tension.
Such action by the U.S. is driven by no other motive than to use religion as an excuse to meddle in China's 'household affairs' in the hope of fishing out political benefits for itself.
