 In response, the United Nations decided to intervene on behalf of South Korea, inviting member states to send forces to restore the situation.As a consequence, American ground forces were hastily deployed in an attempt to prevent the South Koreans from collapsing; however, they too were understrength and poorly equipped, and by early August had been forced back by the KPA to an enclave around Pusan, known as the Pusan Perimeter.Key US allies—Britain, Canada and Australia—also committed forces, although these were initially limited to naval contingents and were largely viewed as token efforts in the US.
