On August 8, 1945, the Soviet Union declared war on Japan and invaded Manchuria. The following day, a second atomic bomb was dropped on Nagasaki, and Japan's resistance to the Allies was quickly ended. Japan decided to give Kim and Vietnamese nationalists the full independence and territorial unification that they had sought for decades. Kim was urged many times to come to Saigon to officially accept control of Nam Bo. Multiple factors prevented Kim from leaving the capital. From August 8 onward, Pham Khac Hoe, Bảo Đại's office director, was instructed by Ton Quang Phiet (the future chairman of the Viet Minh's Revolutionary Committee in Huế) to persuade the Emperor to abdicate voluntarily.
