If we take a look at the way China has been treating Taiwan over the past few years, we will find that it has been using unorthodox methods that have made it a laughing stock in the international community. The incessant attacks on Taiwan make it clear that the mental make-up of Chinese leaders is different from that of normal people. In most international conflicts, there has been hatred between the opposing peoples and national borders have changed, but this hatred has subsided with time. It is rare that such national hatred continues for decades. Except for the hatred between Arabs and Jews, this kind of hatred is probably only found within the Chinese nation.
China has been defeated once by Britain, once by France and three times by Japan. These humiliations have been deeply impressed in the Chinese nation's collective memory. The goal for modern China, whether under the leadership of the Chinese Nationalist Party (KMT) or the Chinese Communist Party (CCP), has been to restore China's past glory.
