"normal" America is exactly what allowed things to get where they are now.
At root, it's 'cuz we're running the beta test Constitution, and deliberately sabotaged it to get the slave states to sign on. That's why 70% of our senators represent 30% of the country. If it were balanced, the first thing Americans would have used their democracy to do is free the slaves, and that couldn't happen. So we ended up with a traditional European feudalism sporting a superstructure of bullshit democracy.
The surprise is that the bullshit held together this long, rather than that it dissolved so easily.
Americans are way too comfortable starting wars because we've never seen the devastation it causes. Even in the Civil War, not much real damage was done. Not like Europe after either World War. I really hope we can outgrow this without being invaded and having our nose rubbed in it.
