Take this as a lesson from us Jews.
Los Angeles, Phoenix, Las Vegas, they're just places, metal and stone.
When the walls come tumbling down, when you lose everything you have, you always have family. And your family always has tribe.
I found it really interesting that you brought up the experience of the Jews. One thing that has always struck me about secular Jews is that they made one very bright, self preserving move during the middle of the 20th century: they established a homeland. A place of refuge where Jews could be somewhat safe.
I often refer to the dispersion of conservatives across the country or world as a diaspora. Because the parallels are uncanny.
