As a South Korean citizen and medical professional, I am deeply troubled by North Korea's recent ballistic missile tests, particularly those involving cluster munitions. These actions not only heighten regional tensions but also pose significant humanitarian risks. Cluster munitions are notorious for their indiscriminate nature, often resulting in civilian casualties and long-term dangers due to unexploded ordnance. The use of such weapons is a blatant disregard for international norms and human life. It's imperative that the international community addresses this escalation decisively to prevent further destabilization in the region.
