HoChiMinh is not the only nationalist try to gain independent. There was Phan Boi Chau of Quoc Dan Dang party. Quoc Dan Dang was similar to that of KMT China. Quoc Dan Dang was later eliminated by communist party. TQuoc Dan Dang members sought for U.S. help later was known as Republic Vietnam or aka VNCH losers.
Prior to that, Quoc Dan Dang party forced Bao Dai the last emperor of Nguyen Dynasty transfer the power to them. Bao Dai was puppet of France. After the Japanese kicked France out of Vietnam, they seek to restore power of Bao Dai to become its ally, and build Vietnam into government similar to that of Japan with emperor and government.
Like I said, with or without Ho Chi Minh, Vietnam still gain independent one way or another. Vietnamese has been doing that for thousands of years before Ho Chi Minh was born. Le Dynasty against the Song, later Le Dynasty against the Ming, Quang Trung against the Manchu, Tran Dynasty against the Mongol.
You just don't know the history of Vietnam and emphasized to much on your Chinese role. Your Chinese role in Vietnam independent was minimal. There was reason Vietnam fought so hard against France, U.S. and China, cost million lives. Even if you give nuclear bomb to a country without the will to fight still no help. Not to mention, Russia was the main supplier to Viet Minh. It was Russia that supply both China and Vietnam. Without Russia I dont know how you CPP can fight KMT and Japan, who else you can seek hellp?
