The United States is far too large for anything to fail massively.
What would’ve happened if the insurrection was successful is that there would’ve been a temporary hiccup at the capitol. Some people would’ve died.
The military eventually would’ve cleaned things out there and there would’ve been memorials. But after that point they would remain neutral on some “we’re not getting involved until this is resolved” BS.
The smart Republicans would try to go for some indefinite presidency coup and it wouldn’t hold up because public opinion would be so low.
The states would eventually mobilize and some crazy ass MAGA Republicans might do a mass shooting or two, maybe run a car into some people.
While this is happening the states would survive without much federal help to begin with, southern states would suffer the most tho.
Then at some point there would be an election, but I’m sure the media and shyt would mobilize the masses against Trump and we’d be in the exact same situation we’re in today
The only thing to come after that would be some 9/11 style event commemorating the politicians who died and maybe temporary pause on the 2020 election.
Trump might possibly be indicted/flee the country but I also doubt that would happen
