Sadly, that is the parallel I see.
What is infuriating is that the “fracturing” is INTENTIONAL for political advantage. It would be one thing if we were facing insoluble problems, but the problems we have such as this MASSIVE invasion from the South IS 100% solvable, we had the solution, we had the laws in place, but...
One party (though, not ALL one party) seems intent on breaking the solutions for their own political purposes.
It’s not all bad. The Roman empire fell apart but the eastern half lived on and on.
