"Dragon Lady" Passes On: RIP Madam Nhu

A shadow from the past has passed on-the widow of President Diem (South Vietnam).
She died at age 87, without (to my knowledge) ever writing her memoires.

I suppose it is the wrong place to ask, but did she ever express her bitterness at having her husband killed (with the acquiescence of the US)?

Wikipedia quotes her:

“Whoever has the Americans as allies does not need enemies”

-Madame Nhu.

So yea, I’d say she was a little bitter.
