That’s very interesting about the Vietnamese family structure. Would Ngo Dinh Diem have been the Tuc for his family?

Big Minh wound up being President right at the very end of South Vietnam’s existence. When Saigon fell he advocated surrender rather than fighting to the bitter end and that surely made him a collaborator to some people. He probably feared that they would come looking for him.

The Tuc would have been someone at least a generation older than NDD.
An elderly man of quiet and scholarly mien who would have lived in an inconspicuous but very comfortable residence carrying out his duties with trusted messengers carrying cryptic hand written messages to others or to the post office or to the cable office.

You are right of course that Big Minh, who probably had at least part of one foot in the VC camp had a lot of Viets right in Honolulu who considered him an arch traitor both for 1Nov63 and then the events of 1975.
