We hope to visit South Africa at some point, with our friend. I'm not really interested any more in the Caribbean. I would avoid Israel now for sure, I thought it was fine when we were there last year. I guess Istanbul is in eastern Europe. I'd go to Poland, not really high on my list.
We have Taiwan on our itinerary, obviously that could change, hopefully not, and Hong Kong. India sounds interesting, we will only touch it for three days though. I'd go to Nepal/Tibet.
Our crazy Turk friend goes to crazy places in Africa, he's in Algeria at the moment. But he goes to Zambia/Congo/Guyana/Ethiopia, etc. He's says they are "OK" mostly.
He traveled the "Solk Road" a couple years back starting in eastern China ending in Pakistan. I'd avoid the latter, and probably the former.
