I'm a bit upset that, toward the end, the author puts politics in an article about history and archaeology, and does it poorly to boot.
For their analogy of "How were the survivors treated today," they cite Border Patrol migrant camps and NYC tent cities.
However, that's not really a good comparison. In both of those examples, the displaced people are foreigners fleeing political / economic disasters (or just seeking a better life).
A closer comparison might be Hurricane Katrina, where the displaced people were (mostly) legal residents or citizens, fleeing a natural disaster.
