The sweet smell

[Vuk]

Uh I'm from New Orleans. The Dykes did fall. They fall all the time.

Cities can be rebuilt Yoyoma. The US cannot. It was created in unique circumstances that allowed for its creation. If the US falls, you will never see its like again in history. And I am not sure if you noticed, but bad things happened to the inhabitants when the dykes broke. The point, generally, is to prevent that.
