That&#x27;s ridiculous. Let&#x27;s take a long view on China from Japan&#x27;s perspective:<p>* Han Chinese displaced people in every direction, throughout what is now China and even into Malaya.<p>* Chinese moved south &amp; west, killing native peoples. (numerous Mongol, Dzungar and Tibetan elimination campaigns)<p>* China takes land from Tibet (1930-1932).<p>* &quot;Chinese unity&quot; includes a lot of places that aren&#x27;t Han Chinese. (routinely interfering in Mongolia)<p>* China previously demanded tribute from Japan.<p>* Republic of China oppressed the Manchu, killing hundreds of thousands.<p>* China wanted to kick Japan out of the mainland.<p>It was only logical to feel threatened by China. If properly unified it would outclass and defeat Japan. They had a momentary advantage and felt compelled to take action to protect themselves against a hostile China.
