One of the first things I saw coming to NYC in 1963 was a graffiti (also a first) painted on the granite steps in Morningside Park. It said "Madame Nhu Go Home!!" Madame Nhu's obit is in the Times this morning and recalls her visit to the US in the fall of '63 to bolster support for the Diem regime in Saigon (her brother-in-law and her husband). Didn't work out.
