We had a north/south situation in Vietnam and we lost 50,000 US soldiers and we lost that war. We lost against an opponent that had inferior technology to USA back then. Even McNamara predicted victory in months and it would be a cake walk. Unfortunately that was incorrect and 10 years later, 50,000 dead americans and the NVA/North Vietnam won and the country was unified under communism. I wonder if we are repeating history and making an assumption of an easy victory again like we did in the 1960s.
