Why do we need in their bunker? Seriously let’s just scare them in there watch them seal the doors and then push a boulder onto their vents and doorways.
Boom modern pharaohs buried with all their wealth and followers and then we can just garden up here. Why do we need anything in their bunker unless they end their world with themselves in which case ok it’s all over.
I see nothing wrong with the wealthy locking themselves in a box in the ground and leaving the whole world to the rest of us.
