Evita was too much of a caricature to be Jewish. The look could be anything, Lenni Bernstein had a Jewish nose prothesis. When she later arrived as an American singer in Israel, a french singer in Sachsen, a danish queen with Parkinson's in Berlin, a sadistic Miriam Naor in Israel, this just makes the British attribution more absurd and therefore plausible.

The most amusing part was the appearance of me and Jolanda in Amsterdam in 1965 in a wedding ceremony. A Jewish heavy area liberated two years later. Now the Dutch identity of Jolanda arranged a lot of FBI connections in Washington. That's something you couldn't do from the London office directly. It would have lost any corrupt credibility on day 1.
At the same time, bleaching the Ass of the British rep in Tel Aviv Jewish textile became impossible on the long run.
