In the mid 1200s, Goryeo, ( Korea ) became part of Kublai Khans Mongol Empire, ( China ). Between 1266, and 1273, Kublai sent six Mongol/Goryeon Diplomatic Missions to Japan, to demand submission to the Mongol Empire. These demands were refused. Between 1274 and 1281, Kublai launched major Invasions of Japan from the Goryeo Peninsula. Tsushima Island and it's inhabitants were virtually wiped out, and numerous atrocities were enacted on Japanese Civilians. Both major Invasions ultimately failed, but the damage was done. In 1592, and 1597, Japan Invaded the Korean Peninsula to enact vengeance for Tsushima. Both invasions failed. Fast track to the 1930s. Japan invades China for past offenses. Untold atrocities are committed in Shanghai, Nanking, and many other Chinese Cities. WW2 is soon underway. My point? Leadership decisions have lasting impacts on the people they are supposed to look after. Kublai only cared about his personal reputation via conquest, and the Kamakura Shogunate failed the People of Tsushima Island. Today? Today the CCP threatens not only Taiwan, but also the Philippines and Japan. Beloud
