A closer, and more literate/intelligent, guesstimate should be: "Didn't US almost took over Korea until China sent her troops?"
Answer would be: Yes. A quick review ...
- North Korean forces invaded South Korea on 25 June 1950.
- On 27 June, the Security Council adopted S/RES/83 : Complaint of aggression upon the Republic of Korea and decided the formation and dispatch of the UN Forces in Korea. As many as twenty-one countries of the United Nations eventually contributed to the defense of South Korea, with the United States providing 88% of the UN's military personnel.
- After the first 2 months of the conflict, South Korean and UN forces were on the point of defeat, forced back to the Pusan Perimeter.
- In September 1950, an amphibious UN counter-offensive was launched at Inchon, and cut off many of the North Korean attackers. Those that escaped envelopment and capture were rapidly forced back north all the way to the border with China at the Yalu River, or into the mountainous interior.
- In October 1950, Chinese forces crossed the Yalu and entered the war. Chinese intervention triggered a retreat of UN forces which continued until mid-1951. After these dramatic reversals of fortune, which saw Seoul change hands 4 times, the last 2 years of conflict became a war of attrition, with the front line close to the 38th parallel.
- The fighting ended on 27 July 1953, when the armistice was signed
Just check Korean war history, a lot available on the web. It does take much literacy or intelligence to do so.
Where did you learn that history? In Singapore, your hometown or somewhere else?
