what if another country staged a coup in the US and deposed trump?

It could be argued that another country has already staged a coup, russia was pretty successful in its endeavour to install trump.

~~What if~~ another country staged a coup in the US and ~~deposed~~ keeps trump because he is a useful idiot.
Russia, mostly.

That ain't happening. If one were to occur here, a coup would be a popular movement or a military one.

The only countries capable of doing that are already getting exactly what they want
- They already staged a coup to install him.
  
  "coup"?
  They fucking brainwashed 70 million+ people to actually vote for it. 😭
  This is hardly a "coup", this is just peak human stupidity.

At this point I feel this is a self-coup, happening in America.
- Every one important nodding along with presidential powers over consititution, and election results, is not a coup. Fixing it would be a coup.

Only way that would happen is if the military lets it.
Is there any country the military trusts more than the current president?
Hmmmm… Canada would be my closest guess.
- Yea Canada would be the only one to even remotely manage that, and that's taking the gamble that the US doesn't launch a nuke before it finishes.
  Being said it would need to be the military, I don't think the average citizen would stop something like that. Especially if the invaders were another democratic leaning country. The only way I think you get civilians to fight is if it ends up being a communist country that tries to invade. The relational ties with Canada are pretty strong, many people have friends who are Canadian, and it's so unlike Canada that I don't think many would believe it was actually them if it was done.
  Hell we're talking a country that basically shrugged and said "oh well they deserved it" when someone shot a healthcare CEO, I can't see anyone batting much of an eye if someone deposed the sitting officials, especially the head of the country, at least in it's current state.
  Being said though.... if something like that did happen, I don't think it will be from a foreign government, I think it would be domestic. Not that it makes it any better.
- I for one welcome our Canadian overlords.
- No sorry I think you're mistaken. Canada is a national security threat
  
  If our barely-more-democratic government and consolidated healthcare is a national security threat, then let me just say this, as a Canadian.
  Sorry.

With all their experience, the CIA should brew one up right now, the country could use it. Just for one in your life, though, try not to install another dictator, install an actual democratic government, as this country really never has had one
- The "good ones" got shoved out the office already (probably out the windows next)

Based on recent events, I'd say South Africa. Because the afrikaners are still bitter about our role in ending their apartheid state, and a significant portion of the United States is racist enough to encourage it to happen.

A foreign country can't stage a coup, only foment one. If your looking for expertise, there are a bunch of CIA guys about to be unemployed.

Considering how powerful the US has in terms of geographical advantage and military prowess, I'd be horrified if any entity is capable of staging a coup in the US... Maaaybe if a few countries somehow convince Canada/Mexico to all work together. But all-things considered it certainly seems like a self-coup is much more likely for the US
- a self-coup is much more likely for the US
  Of course. You're seeing it now.

Ownership should revert to the UK. The founders experiment failed, so just re-establish the previous situation.
- Well, I think we'd have to give some of the Eastern seaboard to the UK. But some goes to France, some to Spain. And tbh a lot could be reallocated back to American Indian groups and councils. Oh, and a bunch would go back to Mexico, too.

  Don't stop there. Where my Clovis people at?

if someone would do it:
Cuba. Or Iran. Or a Palestinian faction.
Why:
Trump's government openly hates Cuba and has reversed Obama/Biden-era openness to Cuba.
Trump had Iran's most important foreign military leader assassinated, he is close with Iran's regional rivals and supports Iran's biggest enemy Israel.
Why a palestinian faction would try to do is doesn't need to be explained, I guess.
- None of those have funds for it without backing from a very wealthy state.
- Por que no los tres?
  
  Yeah, I think it would be the Cubans and Russians at the same time. And they'd get pretty far except for some meddling teens.
  Later, North Korea would reboot the effort.

DOGE cutting CIA funding or something? Gotta open source the intel apparatus now?

The problem is that I don't think any of the countries with the economic means to support a coup have any interest in doing so, and the small list of countries that would support another U.S. coup do not have the economic means to do so.
- Putin is currently staging a coup, and it's on the United States' dime. If all of this is somehow actually the machinations of Putin, you can't help but be impressed with it.

Trump is a symptom of a corrupt system. Removing him is like treating cancer with a bandaid. The entire system must be challenged and overthrown, which includes Democrats and Republicans alike.
Everyone in the comments mentioning Russia as if Israel isn't the largest threat to us.

Trump's children do it, because it is all just so shameful.

LOL
Ain't happening.
conservative 2nd amendment gun nuts will storm the capital and restore trump (or if he's dead, another Magat), most of the military voted trump, dude has full support. There ain't no "coup", you are describing an invasion/rebellion.

Never mind another country. No country's constitution is immune to the military taking over. Israel first, oligarchy 2nd, is a good case for military intervention that couldn't do any worse. Military rule doesn't mean aggressiveness towards other nations.
