South Korean President Yoon Suk Yeol, has just shown that a lot can be done and undone overnight. The 61-year-old President declared a nationwide emergency by imposing martial law, one that would replace the current civilian government with military rule, in a public address on television on Tuesday night. He said that the “anti-state forces” and sympathetic outlook of his political opposition for North Korea led him to take the sudden step. The move was important to "rebuild the free Republic of Korea” and protect the country from “North Korea’s communist forces”, he added.
