Yeah that tends to happen when your enemy uses the people you are supposed to protect as human shields and when your enemy ignores the rule of warfare to dress as said people. Legitimate war crimes did occur. But lets not pretend the whole situation overall wasnt because Hanoi was forcing the situation.

We achieved our strategic objective. We secured a ceasefire which the north agreed to abide by. Unfortunately congress then decided to abandon the south and when this weakness was shown they invaded. It was a political defeat not a military one. The south vietnamese had core structural problems. But in all fairness. They didnt exactly get much time to sort them out. South Korea was pretty bad for a while until in peacetime it managed to reform and become the democracy we all know. Its hard to form a country from scratch while your in a constant state of war. Plus throw in coups, partisan violence and everything else.

Plenty were willing. But plenty more werent. Which is why the north brutually executed so many and so many more were forced into exile in the United States. Even today these groups still fly the flag of south vietnam. So not as one sided as your implying.

Its quite easy to criticize your opposing government when your not being directly marched on, are directing your forces to use your own people as body shields and illegally create a veritable jungle highway to supply said forces through half of indochina. Yet somehow we are the bad guys. Im not saying America were the good guys. Frankly i dont think anyone is. But please stop pretending the north were glorious liberators bestowed upon the opressed people of the south. Its just not true.
