If I was doing a PhD in modern history I would study the transition from the (relatively) sane world of the 60s and 70s, the changes brought in during the 80s by Reagan/Thatcher and their effects we are still experiencing today.
Didn't feel like it at the time, but the 70s seem to have been the last decade when the general consensus was that society was important and we didn't have a world where success was measured by how many people you could climb over to get nearer to the top.
We now have a world led by people brought up in the 80s and 90s who don't know any different and they believe their world is normal and good.
In order to save the state Trump has to destroy it, that's why he sits at his desk waving his pen, signing stuff into being that in many cases he has no authority to do, stuff that runs straight into a roadblock in the courts.
This is wrecking ball stuff in a hurry, he's a destroyer not a creator, he has no clear ideology beyond unfettered self interest. He isn't even a fascist, fascists actually believe in something. He's a sociopath, a ragbag of right wing prejudices, he has no clear ideas that last longer than his last utterance, the thoughts of the last guy in the room. He uses fascist tactics for sure, because fascists are authoritarian and he's an authoritarian and it's the only way he can get rid of stuff fast, stuff that prevents him from winning for himself and his buddies and winning is what it's about,
But winning, winning a lot and all the time, creates losers, lots and lots of losers.
So it's fuck Ukraine, fuck Mexico, Canada, Greenland, Gaza, The EU, NATO, America's standing in the world, all that wonderful soft power decades in the making, fuck his followers, the poor and even fuck the American economy, which he reckons he'll patch up, sort of, somehow, someways down the road.
But when he fails miserably, which he will, it'll be fuck the lot of you! Coz he'll still declare a win, coz it will be for him and his mates, because, as we all know, in the end that's all that matters.
