Sep-07-21  BIDMONFA: Coenraad Zuidema


Aug-29-22  phantasmagorium: Hmmm... a Dutchman born in the Dutch Indies (now Indonesia) during the Imperial Japanese occupation period. Interesting. I hope I am not opening an old wound, but I do wonder if he (or his parents) might have a few harrowing stories of those days.
Aug-30-22  Olavi: Or perhaps about the Dutch Politionele acties of 1947-49 (read: colonial wars) against the Indonesians.
Aug-30-22  phantasmagorium: <Olavi> Yup. Those would not have been an easy time for anyone there too. I could only wonder, when he/his parents moved to the Netherlands.
