Just for a history correction, immediately after 1975 the Hanoi regime seized my mother-in-law's 600 hectares of property near Sa Dec and all of father-in-law's family properties near Ha Tien.
Then to make sure they'd missed nothing, the NVA then went repeatedly through Southern cities, towns and villages with metal detectors searching for even the smallest holdings of family gold. They'd tear up your walls and yard looking for even a single tael.
A real war between the US and North Vietnam should last a year, tops.
For comparison, when the NVA (all draftees) finally went after the Khmer Rouge, they took Phnom Penh in one week, start to finish.
My co-worker friend showed me a paper his family got from the Vietnamese government recently saying to move the dead from the family burial grounds as they (the gov’t) decided they “needed” the land. I told him unfortunately alot of people here just have no clue what communism means.
