South Koreans certainly have much to thank the Americans for. Without UN intervention in the Korean War, led by the US, the South would have been taken over by Kim Il Sung, the Great Leader, and their current freedom and prosperity would never have been possible.
南朝鲜人肯定有理由感谢美国。没有在美国领导下联合国对朝鲜战争的干涉，南朝鲜就会落到伟大领袖金日成的掌控之中，而它现在的自由和繁荣也就会成为永远的梦想。
