Below is a statement from President Harry S. Truman, June 26, 1950. Our concern over the lawless action taken by the forces from North Korea, and our
sympathy and support for the people of Korea in this situation, are being
demonstrated by the cooperative action of American personnel in Korea, as well as
by the steps taken to expedite and augment assistance of the type being furnished
under the Mutual Defense Assistance Program.
Those responsible for this act of aggression must realize how seriously the
government of the United States views such threats to the peace of the world. Willful
disregard of the obligation to keep the peace cannot be tolerated by nations that
support the United Nations Charter.
