Final answer:
Following the defeat of French forces at Dien Bien Phu in 1954, Vietnam was divided, affecting the Viet Minh by blocking the reunification they sought under HoChiMinh's leadership. The South, under Ngo Dinh Diem, resisted the promised elections, maintaining a separate, non-communist state.
Step-by-step explanation:
Impact of New Government on the Viet Minh
After World War II, the French intended to regain control over Vietnam, their former colony. This led to resistance from the Viet Minh, a nationalist group led by HoChiMinh, who fought for Vietnamese independence. Following their defeat at Dien Bien Phu in 1954, the French were forced to abandon Indochina, leading to a temporary division of Vietnam at the seventeenth parallel. The Viet Minh controlled the North while a non-communist government was supported in the South.
Eventually, Ngo Dinh Diem became the leader in the South, refusing to follow the Geneva Accords that called for national elections, thus impacting the Viet Minh by preventing reunification under their favoured leader, HoChiMinh.
