Something misfunctioning doesn’t mean it doesn’t exist. A massive economy, industry and war machine are still here. Pretending that doesn’t exist because it doesn’t work the way we like is an expression of exasperation, not a description of reality.
Those things are exactly what destroyed the nation. The military industrial complex and the billionaires who removed the teeth from institutions that used to prevent the accumulation of power (see also: antitrust litigation against Standard Oil). Those entities are now in complete control and democracy is nothing but a sham, a clown show between two faces of the same coin.
The US as a country didn't fail with Trump. It failed when Microsoft got away scot-free. This was the biggest sign that the country was no longer a serious entity, because a serious entity would try to preserve its own power, while the United States of Burgers is something to be sold to the highest bidder.
This level of doomerism is absurd. Of course the US will survive this administration. I blame the news for making every breathe by whichever opposition seem like the next WWIII.
That is gone my friend, with the wind like a sulfuric fart, for good. US is becoming a global terrorist and enemy #2 of free world and certainly whole Europe (right after its biggest and only 'friend', russia which coincidentally keeps trying to make you a thing of the past). This comes from somebody who strongly believed in your role in global hegemony despite your numerous well documented fuckups in the past. All on the whims of one visibly mentally sick man, with absolutely nobody standing up to him despite nobody really believing in any of that bullshit. No principles, just plain greed and firm fuck-the-rest approach. Right now, if Europe needs a strong big ally it will be #1 China, and then... nothing.
The fact you voted him in, and he still has massive support, and there has been 0 overthrow attempts of the biggest traitor to US in its history tells me and everybody else in the world many things, but nothing positive. Even if next election, if they will happen, will have 98% win of the democracts with that ridiculous unfair and undemocratic system of yours, it won't change a permanent shift that started and keeps happening. US has no real allies, in same vein russia or China has no real allies.
Empires rise and fall, inevitably, there was never a reason to think US would be an exception.
