In 1954, there had been hostility to the NNSC inspections by the South Koreans, and doubts by the UNC, Switzerland and Sweden about the balanced application of inspections. On 31 July, after warnings from the South Korean military that action would take place if the NNSC did not withdraw from South Korea, demonstrators attempted to enter the Incheon NNSC camp, but were stopped by United States guards. After discussion within the NNSC, and with the agreement of the Military Armistice Commission, the inspection teams' strengths were reduced by about half.
