The country was in decline for at least a decade before Trump took office.

Well 4 years of that decade was Trump being in office, and 4 other years was the result of people being willing to vote in literally anyone who wasn't him. So really 8 years of that decade was Trump's fault. And the other two years? Not bad.

As for the rest, Trump is cutting funding for research like crazy. That won't just affect things today, that's going to make stuff shitty for decades. And that's exactly the kind of harm that the emotion-laden American news and social media simply won't cover. So I don't think there will be a backlash, rather the opposite - politicians will realize bullying scientists, government agencies, immigrants, and other voiceless Trump targets is just good politics, and keep doing it.

Of course future prediction is hard, so who knows what will happen. But I'm not seeing the path for this to turn around anytime soon. The same media that created MAGA, and made it even more popular 4 years after it proved itself to be a horrific disaster is the same media we have today. Democrats will probably win the next two elections because people can see what Trump is doing in real time, but after that I have no hope for America. If I have to predict the future, I'd guess the EU becomes the new global leader, driven by relatively high democracy and pro-science policies compared to the rest of the world. This could even occur in a relatively short time frame, like 5 years.

This usually happens, yes.

After millions people have died.

Not worth it. Trump and the other right wing extremists should have been stopped years ago.

Idk we got biden instead of Bernie Sanders in 2020... I doubt it will improve

For every action there's an equal and opposite reaction?

That is what I'm assuming too.

Would be nice if it wouldn't be causing so much death, destruction and suffering before you got there

Absolutely not, not only will this administration not make anything better everything will become significantly worse. For this example I will assume that there is an election in 2028 (massive assumption, ill get to what if there isnt):

1. The Democrats will run a Trump lite but with absolutely nothing Trump had that made him popular, instead the next Democratic candidate will essentially copy Trumps policies but not as bad and more efficiently. See how the Democrats responded to Reagan and Bush.
2. When the Democrats go significantly further to the right so will the Republicans, in 2034 the Democrats will be as right wing as Trump is today. This will become the new norm, Fascism will be an openly accepted talking point, and everything will get worse.
3. Bipartisan legislation will ensure fascism remains uncontested and nobody will vote third party since thats a "waste of a vote". People on world and other similar liberal platforms will insist its the fault of third party voters and nonvoters for not voting hard enough. Massive campaigns will occur where the Democrats insist that even though they only ever pass bipartisan legislation and that legislation is always fascist they're 5% better than the Republicans.

But we may not even have a 2028 election and if so:

1. People will make large protests that get shut down quickly.
2. Fascism takes hold, few resist
3. Things get worse

It will help change worldwide lol, not sure about the US

STUPID Libtard! I LOVE what Trump is DOING!

This is overly simple. You can't legitimately believe that an explanation only focusing on one person is sufficient to predict American politics. Nope, no chance. Meh.
