In the 80s I had the pleasure of visiting sites in Iraq and in the 90s in India. To me it was fascinating to see and actually meet ancient communities there - of not only Jews but Mandaens, Zoraostrians, Assyrian Christians, etc. etc.
Besides the visit to Kresy/Polin when the quarantines finally get lifted, I would also suggest visits to Kochi in southern India - the synagogue there with a community history dating back to 500 BC (as I’ve noted in my other posts) is something the West forgets - thinking that Judaism and Christianity are purely “European/Western religions”
My doc is an Afghani “Son of Solomon.”
