During the Korean War, because of the intervention of the United States, North Korea was in a difficult situation for a while, so it chose to ask its boss, the Soviet Union, for help, hoping that the Soviet Union could send troops to the Korean Peninsula like the United States to help itself. However, for various reasons, the Soviet Union did not agree to the dprk's request, but instead consulted with China, hoping that our country could send troops, and then they provided assistance behind their backs, plus the DPRK also sent a request, on the other hand, China also considered its own security and finally decided to enter the war. However, during the Korean War, the United States wanted to expand the battlefield to China several times, so why did it finally give up?
After China joined the battlefield, the one-sided war situation finally began to change, and after several confrontations, the United States realized that although the volunteer army was not as well equipped as them, it was really not easy to deal with, which also made the United States feel very angry. However, the United States absolutely did not want to lose, because they also invested a lot in the Korean War, and the longer the war lasted, the more unfavorable it was to them, so the IDEA of pushing the front line to China itself was born within the US military, and even the atomic bombs were transported to Japan at the worst time. As for why they eventually gave up, it was mainly because there were two reasons.
The first is that even if they attack China, they cannot be sure that they can win. China's territory is very large, and it is difficult to solve China at one time, and the encounter with Japan at that time is the most typical example. If the United States really sends troops to attack China, they will need more weapons and troops, and that kind of attrition is very terrible, even if the United States is as rich as the United States does not dare to try easily. In the Korean battlefield, the United States already had a deep understanding of the combat strength of the volunteer army, and they knew that this was definitely a vicious battle, so they had to be more cautious.
The second was that they feared that a shot at China would involve the Soviet Union in the battlefield. China and the Soviet Union are geographically closer, plus Sino-Soviet relations are relatively friendly, and more importantly, the Soviet Union has always been providing assistance to China, if the United States has hit China itself, the Soviet Union will have no reason to continue to secretly help. If the Soviet Union entered the war, the probability of the outbreak of the three wars was even higher, and this is exactly what the United States and the Soviet Union wanted to avoid.
Therefore, it is impossible for the United States to really burn the war to China itself, although they are shouting very hard, but if they want to say it themselves, they may also say that this is a matter of gain and loss. The US military's words are so frightening, mainly to intimidate and threaten our army.
