I lack the imagination necessary to guess what would be next. I agree with you that America ending is the only eventual conclusion. But I think the actors involved don't even know how to do it. None of these people know what genuine conflict is or how to do it. Their lives are built on comfort.
We're at the precipice and all actors involved are confused and comfortable. Abbott doesn't want a civil war. He's a millionaire. No elected official in America is prepared for a situation where they might reasonable be assassinated or their house burned down. None of them want a warzone in their front yard. They want to continue their happy little lives going to PF Chang's every Sunday and trips to Venice every year.
It's all theater until the moment they're ready to die.
