Not OP, but I somehow share his sentiment and I'd say that out of your list any would do. Terrible things are happening right now, and people find their way out, for instance the war in Ukraine. But then again, they have visa cards, they can book travel and accomodation online and flee from the country. A lot of jews have fled from Europe during and before WW2 when things were not so much connected, but still, it was modern day, people had access to press, radio, telegrams and telephones. But if you live in a rural village and everyone you knew died to a famine that sounds like something you might not want to carry any further.
