I think your normalcy bias might be showing here:
> In reality, the US government is one of the most static, unchanging organizations on the planet.
The changes in that past couple of months are, objectively, enormous disruptions to the previous status quo (of the last 50+ years).
NATO may still exist on paper, but not in the world. The US has estranged almost all of its closest allies that it's had for my entire lifetime — I'm 50 — and in ways that are offensive, threatening, and simultaneously weirdly petty, and which would take a decade or more to repair even in the unlikely event that somehow the current administration was somehow replaced today, and efforts began immediately.
The US president has also opened up avenues for corruption and out-in-the-open bribe-taking (meme coin, banks of hotel rooms, his wife's vanity projects, etc etc etc) that are absolutely unprecedented in US history, of the ilk historically seen more in places like Malaysia, Peru, or the Philippines under Marcos. (Even Silvio Berlusconi was substantially more tactful and less obvious about it.)
At the same time, the administration is performatively flouting the rule-of-law, in ways completely unprecedented in the past 50 years. Openly defying judicial orders. Disappearing people without due process (yes, like all fledgling autocracies, they are starting with the already marginalized; purported gang members, brown-skinned or Asian permanent residents).
The childhood parables like "The Emperor's New Clothes" never actually, like, literally occurred in the America I knew, until this guy. Last time it was just "my crowd was bigger than Obama's" but this time it's "Ukraine started the war" (somehow arranging to be invaded by a murderous dictatorship waging a campaign of rape, torture, and mass child abduction).
> Nothing is going to happen in the next 4 decades let alone the next 4 years.
Way more than "nothing" has already happened. More substantial, self-directed change has already happened in 2-3 months than in Trump's entire first term, or any term of any president, in 50-100 years. I strongly suspect this trend will continue.
As you can no doubt infer, I am not a huge fan of this administration. But neither am I a partisan; I would characterize this administration as worse than any administration, Republican or Democrat, of my lifetime — and by a lot. (I include Trump's first term in that, but only because that static, glacial-pace US government you think still exists did still exist then, so even though the graft and weird dictator-fetish/emulation was present then, too, it didn't have the impact that it's already had in this term.)
Whether you think it is worse or better, I mean, we all have different priorities but it is unarguably very different — and has already made the US government very different — than anything seen in the past 50+ years.
