South Korean President Yoon Suk Yeol said on October 1 that North Korea will face the end of its regime if it attempts to use nuclear weapons, warning a "resolute and overwhelming" response from the South Korea-U.S. alliance. President Yoon made the remark during a speech marking the 76th Armed Forces Day, as North Korea has intensified its nuclear threats with the first public disclosure of its uranium enrichment facility last month.
