Records of Volunteers Aiding Korea

This is a decision made under the conditions of extremely complex international situation and severe domestic situation in our country, with a lot of waste waiting to be done and many difficulties. So why did Mao Zedong insist on sending troops? Does it seem correct today? Why did Stalin go back on his word? What was he hiding? Chiang Kai-shek, who had retreated to Taiwan, attempted to send troops into the DPRK. For what reason did he fail to send troops later? This is a confrontation with a huge disparity in power. The enemy is the so-called "United Nations Army" composed of 16 countries headed by the United States and the South Korean army. Our side is the two armies of the Korean People's Army and the Chinese People's Volunteers. The enemy has almost all modern weapons and equipment such as aircraft, tanks, artillery, and warships, but I only have backward equipment such as rifles and grenades. This is a typical "asymmetric combat." So, what is the combat effectiveness of the US military? How do we win or lose? What is the reason for my victory?
