I dunno know....ask the 100,000s who fled in rickety boats into pirate infested waters to escape the NVA wrath how it felt then.
The Ho and Giap generation has died off and liberalized the country no question of that
I always thought of those poor kids dying in the mud and red dirt as life oozed out of them and the thought that one day soon enough the folks who killed them would ask us back to Cam Ranh Bay etc to buffer Chinese intentions
War is about the immediate sadly and often seems such a waste in hindsight
