On June 27, President Truman tells Congress that he had already approved the use of the U.S. Air Force and Navy to defend South Korea. He calls it “a police action,” fully mindful that Congress would have to approve a Declaration of War.
On the same day, the United Nations Security Council passes American-drafted Resolution 83 that recommends “Members of the United Nations furnish such assistance to the Republic of Korea as may be necessary to repel the armed attack and to restore international peace and security in the area.”
The resolution marks the first time that the United Nations steps in to aid a nation against an invading force.
Also on the same day, South Korean President Syngman Rhee and his top government officials evacuate Seoul. A number of South Korean Assemblymen are captured and forced to swear allegiance to the North.
