Naziism is just an ideology that appeals to some common instincts, which becomes an issue when enough of them are in precarity that they warm up to making the ideas policy.

It doesn't make for a very good state. Incompetence and nepotism rises to the top. Data driven science is tossed aside for ideology-driven rhetoric. Officials govern on vibes resulting in famine, plague and war. Also the country turns into the very kind of shithole it accuses other nations of being.

Eventually, you have bombers from rival countries blocking the the sun over the capitol. International tribunals exercise judgement and enforce their law, since the nazis failed to provide rule of law to their own. Children pick up pieces of the trainwreck.

And we learn (or fail to learn) once again why we don't let the fascist autocrats take over, even when they are very, very rich.

We in the US have a choice: clean up the mess early, or let China clean it up for us. And China will make us jolly sorry if we make them clean it up. We'll be their buggery bitch for a century or two at least.
