Martial law was declared, and then quickly lifted, in South Korea. The declaration was allegedly clearing the way to root out North Korean subversion throughout the country. It was made by South Korean President Yoon Suk Yeol on Dec. 3. The country’s parliament voted to end martial law, which was lifted not long after. But the issue still stands over whether the country has been subverted by North Korea, and what may still be done to tackle the issue.
