The Pentagon Papers describe the formation and power of the Viet Minh (1970). The Pentagon Papers were a series of classified documents that were made public.

"[T]he Viet Minh was the main repository [warehouse] of Vietnamese nationalism and anti-French colonialism. There were other such groups promoting Viet independence but none were competitive on a country-wide scale. It is also true that the disciplined, well-organized, and well-led Indochinese Communist Party was the controlling element in the Viet Minh...

ICP strategy was to unify nationalist elements to achieve the immediate objective of independence... [T]he Viet Minh was sufficiently popular and effective to turn itself into a Vietnam-wide government that could have extended its authority throughout the country after World War II - except for the obstacle of reasserted French power... However, it seems likely that in the absence of the French, the Viet Minh... would have overridden indigenous tribal, religious, and other opposition in short order."
