Brazil. I'd pick the largest geographical country that way if you are marooned in only one country you are stuck in a tiny zone.
I was going to say Brazil but they seem to be heading to hell recently.
If they were more stable I'd agree.
I would seek the protection of the Catholic Church. They apparently have an awesome underground railroad that makes people unfindable.
Cuba. For the food. Oh, and the music. Oh, and hot young Cuban men. Yeah, and I could take up smoking good cigars.
So yeah, Cuba.
Well my choice is not even on the list. I would stay in Hong Kong or Main-Land China. Great women, and a up-coming economy.
Many of those on the list is in various states of dis-array, good for vacationing to enjoy a change of pace, but after a few months that may get old.
For example ...in Cuba ..with cars from the 50's compared to Hong Kong watching the latest movies and even getting better I-phones than we have here in the US. Depending on your personality this would be a major issue.
Detroit. The American dream got lost there, so I imagine little old Snowden can certainly get lost there, too. After all, who'd bother to go there to look, anyway?
