President Lee Jae Myung is set to host a governmentwide regular security meeting Monday to assess the nation's security posture and response measures, Cheong Wa Dae said. The integrated security meeting, the first since he took office in June 2025, comes with the U.S.-Israeli war against Iran entering its fourth week and appearing to move to another dangerous escalation as U.S. President Donald Trump gave an ultimatum to Iran to reopen the Strait of Hormuz. The meeting will bring together Prime Minister Kim Min-seok, Joint Chiefs of Staff Chairman Gen. Jin Yong-sung, acting National Police Agency chief Yoo Jae-seong and senior officials from relevant ministries to discuss coordinated security measures. Attention is expected to focus on whether Lee will address the situation in the Strait of Hormuz, which has effectively been closed following Iranian retaliatory strikes in response to U.S.-Israeli military operations. Meanwhile, Cheong Wa Dae denied a media report that National Security Adviser Wi Sung-lac has been planning to visit Washington.
