On May 25, 2009, North Korea conducted its second nuclear test, escalating regional tensions and leading to swift international condemnation and calls for unified responses from South Korea and the U.S. Despite no radioactive material being detected in the aftermath, the test was perceived as a tactic to draw attention away from North Korea's economic struggles and to assert its nuclear capability. The U.N. Security Council adopted Resolution 1784, imposing severe sanctions on North Korea, which was met with threats of military retaliation from Pyongyang.
