Nevada isn’t just Vegas. There’s a big values dissonance between Vegas and the rural North, and if the country starts fracturing I don’t see them staying together.
I could actually see Vegas seceding from Nevada to either join with California or become an independent city-state.
Fallout: New Vegas would become real, in other words.
Well, I only know of two off the top of my head, but I really doubt they’re the only examples: Irish and Mandarin Chinese.
I think some Irish don’t even habitually use them when speaking English. If you ask them “Are you ok?” they’d answer “I am” or “I am not.”
