Kim Il Sung Division of Korea At the end of World War II, the Korean Peninsula, which up to that point had been occupied by the
Empire of Japan, was divided along the
38th parallel north. The Soviet Union (USSR) had moved forces into the northern half of the country, overseeing its establishment as the communist
Democratic People's Republic of Korea (DPRK) under
Kim Il Sung, a figure who had previously risen to notability for his successes fighting the Japanese. As tensions rose between the US and the USSR, each government in Korea claimed it had sovereignty over the whole country. On 14 November 1947, the General Assembly's Resolution 112 established a temporary commission to monitor free elections in Korea. The UN had intended to reunify Korea under one government, As the pressure built, the North Korean government became more aggressive, with skirmishes between North and South becoming common. UN military observers were assigned to monitor the situation, ostensibly to prevent it from escalating. General Assembly Resolution 293, passed on 21 October 1949, recognized only the southern government as legal. The numerically superior North Korean forces overcame isolated resistance from the 38,000 South Korean soldiers on the frontier before it began moving steadily south. Most of South Korea's forces retreated in the face of the invasion. News of the invasion quickly spread around the world via ambassadors and correspondents in Korea. Journalists in the United States were reporting on the invasion within five hours of the initial attack, and United States Ambassador to Korea
John J. Muccio sent a telegram to the
US State Department at 10:26 KST June 24. As the combat grew more intense,
US Secretary of State Dean Acheson informed President Truman, who had been resting at his Missouri home over the weekend), and
Trygve Lie, the
Secretary-General of the UN, of the situation. The attack was particularly troubling to Truman, who likened it to the Japanese attack on Pearl Harbor, and to Lie, who was reminded of the
invasion of Norway during World War II. Fearing the attack would spur another general war between great powers, Truman resolved to act as quickly as possible to prevent an escalation of the conflict. Muccio met with Rhee, who informed him the South Korean Army would run out of ammunition within ten days, and would not be able to hold back the invasion on its own. He requested the United Nations and the United States assist South Korea in the conflict. Lie convened the Security Council for its 473rd meeting at 14:00 June 25 in New York City. He began the meeting with a detailed report from the
UN Commission on Korea, explained the situation to the delegates, and insisted that the UN take action to restore peace in Korea. According to the UN Commission on Korea, the situation was assuming the character of full-scale
warfare. The United States introduced a resolution stating that North Korea's invasion was a breach of peace in violation of
Chapter VII of the UN Charter. == The resolution ==
