United Nations Security Council Resolution 82 (1950) of 25 June 1950
The Security Council,

Mindful of the concern expressed by the General Assembly in its resolutions 195 (III) of 12 December 1948 and 293 (IV) of 21 October 1949 about the consequences which might follow unless Member States refrained from acts derogatory to the results sought to be achieved by the United Nations in bringing about the complete independence and unity of Korea; and the concern expressed that the situation described by the United Nations Commission on Korea in its report1 menaces the safety and well-being of the Republic of Korea and of the people of Korea and might lead to open military conflict there,
