This week marks the one year anniversary of Honduras ceasing to recognize Taiwan and instead only recognizing China. Over that time period, China and Honduras have gone through several rounds of negotiating a free trade agreement, with trade expanding. Additionally, they have just signed a $275 million cooperation agreement, providing education infrastructure for Honduras.
The other major news piece relevant to Honduras is the battle against Prospera, a US-based crypto libertarian firm that sought to buy a private island in order to create an ancap paradise, in which Bitcoin would be legal tender. In 2022, Honduras killed the island's special status that made the deal possible, and so Prospera is seeking $11 billion in compensation.

A thought experiment for Hexbears (not a spoiler for the Three Body Problem series, I’m not going to say how it played out in the books, but certainly inspired by it):
If America had launched a first strike against China that will wipe out 90% of its population, should China retaliate?
If yes, then hundreds of millions of innocent Americans - who played no part in the aggression - will be killed in a mutually assured destructive process. The retaliation will not in anyway bring back the lives of those who had been targeted during the first strike. It only adds more suffering to the world’s innocents. Worse, it will trigger a global thermonuclear war with a very high probability of wiping out human civilization altogether. The end of humanity as we know it.
In this case, does it make sense to retaliate against a first strike then? Is vengeance that important, even if it means killing millions of innocent people as a result, the end of the entire human race?
Or should the survival of the human race be upheld as the priority, or rather, the utmost priority to harm no innocent, even if it means some people had to be sacrificed in the process because of the “mistakes” of certain bad actors?
Can humanity collectively learn from such “mistakes”, if the receiving side had restrained themselves from retaliating, and thereby giving the rest of humanity a chance for survival and to learn from their previous errors?
This is a peak Chinese liberal thought experiment. The population of every other nuclear power (except maybe the soviet union before it collapsed) knows the importance of MAD and would unequivocally advocate for revenge. Westerners have been fantasizing about exterminating all none-white for centuries. American politicians quote the Turner Diaries when they think nobody will notice. In Oakland, a city with one of the highest Asian populations in America, they have a square called "Jack London Square" named after a man who wrote about how he wanted to use biological weapons to exterminate all Chinese and then hunt down all the survivors. They teach this man's writing in gradeschool. For every person protesting Israel in the west there are 2 more who derive genuine pleasure from the suffering of Palestinians. Where do you live? I'm genuinely curious how anyone can come up with a thought experiment this naive. Have you just like, never talked to a westerner outside of hexbear or something?
The doctrine of nuclear deterrence only works if there is a credible threat of a second strike. Once it has been established that nuclear victims will not retaliate, it is open season for atrocities beyond your comprehension.
The credible threat of a second strike prevents a first strike. In order to have a credible threat, you must be actually willing to go through with it.
The best way of making a credible threat is to make it so that you have no choice in the matter. Russia's Dead Hand system automates the second strike, removing all human agency. Computer systems do not think about philosophy before dropping the other shoe.
The best way of making a credible threat is to make it so that you have no choice in the matter. Russia's Dead Hand system automates the second strike, removing all human agency.
This is actually a very good point. But do you think the fate of humanity should be trusted entirely on a computer system? With no input from an actual human being at all?
If there is indeed some level of intervention from humans, then it already defeats the purpose of having an automated second strike. Because that one (or a few) people with the power to intervene will hold all the cards to end humankind as we know it.
Dead hand only gets activated in times of great military tension. One of the proposed ways to get around MAD is a "decapitation strike" where you prevent a retaliatory strike by destroying the other side's command infrastructure. The point isn't to make the decisions for humans, the point is to make sure Russia/The Soviet Union still has second strike capability even if everybody in Moscow has been turned into radioactive ash.
If America had launched a first strike against China that will wipe out 90% of its population, should China retaliate?
Yes, the destruction would lead to world socialism and eventually galactic communism /j
but honestly yes, if country tries to wipe another one with nuclear weapons then the country in question should retaliate, i dont think humanity would collectively learn from that mistake if the china doesnt strike back, the world saw the destruction 2 atomic bombs did and it didnt stop the developing and constructions of more bombs with even worse destructive ability, only way we learn is if we experience a nuclear war and if that means the extintion of Humanity then it was probably deserved for building such terrible weapons
Can’t say I disagree, but damn that’s a bleak view of humanity. Do you think the American people would rise up against the reckless use of nuclear weapons, thereby bringing down the global hegemonic empire for good? Not even a small chance?
Damn, we are truly doomed then if the response to a nuclear genocide is one of celebration.
I suppose they will simply justify the action by equating China to the nuking of Japan nearly a century ago, which in many of their minds were fully justified.
nope, if they arent punished in any way i dont think they will learn anything, only reason they didnt let macarthur use nukes to stop the chinese advance in the korean war was the fear of escalating the war, Germans only revolted against the Kaiser when the empire was on its last legs with martial law, food shortages and other stuff after suffering from the horrors of world war 1 which they cheered and supported at the start
if the USA did that and it wasnt punished i dont think its people would just grow a concience and try to be better if anything i think they would become worst, after that great crime who could stop them from doing it again against those who cant strike back like Venezuela, Iran, etc.
I think this is why Israel ended up the way it did. Germany didn't suffer enough for its crimes. zionists decided that if Germany can be forgiven in a few decades, Israel should do the same.
if you don't enact MAD when it counts then we'll live in a hellscape with open nuclear attacks going unchallenged. The 10% of people who survive got to remember the lesson or it will happen again and again.
Also, yes they should do it because fuck Amerikkka they can't keep getting away with it.
In principle, I agree. But what if America nuking its enemies finally led to its docile people to rise up against the reckless imperialism, ending the global hegemonic power of the US empire for good?
If it is instead followed by a second strike, then it’s game over for all of us. Everyone loses. There will be no future - let alone a socialist future - for the billions of the world’s population who had nothing to do with the initial aggression in the first place.
finally led to its docile people to rise up against the reckless imperialism
The people in this forum are an extremely small minority. People regularly justify the use of atomic bombs on Japan. White Americans literally "joked" about nuking China 24/7 during Covid. The west is literally committing a genocide on Palestinians as we speak.
That term reminds me that some scifi like Halo and Ender's Game will literally just offhandedly go "and btw the Aliens killed all the Chinese/Indians" and users will treat it as a positive.
Big stick diplomacy is in effect for the vassal allies too though maybe it's more rare to have it spelled out publicly. At least there's that famous Kissinger quote about US friends and enemies.
As first reported on social media by Jacob N. Kornbluh of the Forward, Governor Hochul stated to an audience of the United Jewish Appeal-Federation of New York that “If Canada someday ever attacked Buffalo, I’m sorry my friends, there would be no Canada the next day.” The statement was made on Thursday, February 15, and went viral the following day.
Hochul, who hails from Buffalo, New York, added that she “loved Canada, but we did have the War of 1812 and they did burn Buffalo.” She further elaborated, “But think about that. That’s a natural reaction. You have a right to defend yourself and to make sure it never happens again.”
Yes. MAD is why governments exert extreme controls on their own nuclear protocols and the whole point of MAD is that China, Russia and the US would retaliate and kill the entire population of the aggressive nuclear power. Of course China 'should' retaliate, because that is what prevents the scenario from happening in the first place.
What is irrational is the french nuclear doctrine of 'if you sink one of our ships, we'll nuke you'.
If 90% of China was killed in nuclear war the USA would not let the remaining 10% survive. They would hunt the rest of them down with drones or sanction/blockade them to death. At that point it is more important to return fire with every thing they have because the only way for the Chinese people to not be exterminated is if USA is in as bad or worse a situation.
Yes. In order for MAD to work, there has to be a credible threat of retaliation. By not having a second strike policy, you allow the first strike to happen.
The question is only really a philosophical problem if you're assuming that China and the US are the only two nations on the planet. Given that other nations, especially nuclear nations, exist, then I think a second strike against America (and perhaps the UK and France and other Western nuclear nations, but not necessarily as they don't have the ability to dominate the world in nearly the same way that America could hypothetically do if America had a competent imperialist strategy unlike today) is the only correct choice. America and China are irradiated hellholes and billions have or will die, but it's a world with one less hegemonic imperialist power, and that's a world that does still have a potentially communist future.
Someone other than me would have to make the call about whether preventing a global fascist future (that might even go spacefaring and propagate colonialism and imperialism throughout the galaxy and universe) is worth the death of absurd numbers of people - all I can do is say that this is the decision Stalin made, and I regard him as a pretty smart and competent person.
It wouldn't matter. There is no way to replace the global industrial output of China on the world stage if the labor force from which that industrial output is derived is knocked out. The globe would immediately spiral into a recession the likes of which no one has ever seen, particularly with the vaporization of most of the world's smart phone manufacturing infrastructure, battery infrastructure, and components infrastructure.
They would be ethically obliged to retaliate, but the world would be essentially fucked for the next three to four decades regardless of any other actions.
yes. not responding would potentially allow america to begin nuking its enemies anyways, hell fear of opening themselves to that kind of reprisal I'm pretty sure is why they haven't nuked tehran yet
Not surprised at this answer looking at your username lol.
I guess the question is what is the use then if all the people are dead anyway? Provocatively, do American children deserve to die in a nuclear firestorm just because their leaders are insane enough to commit a mass genocide? Do the people from the imperial core still have the redeeming quality of bringing down their genocidal regime in response to the reckless use of weapons of mass destruction?
do American children deserve to die in a nuclear firestorm
American children regularly "joke" about nuking other countries and exterminating other cultures/races. As we speak some middle schooler is probably justifying the use of nuclear weapons on Japan in some history class discussion.
Do the people from the imperial core still have the redeeming quality
No
Did Guanyin get a hexbear account or something. This is kindness to the point of immorality. If China doesn't retaliate in this situation would only embolden the West to kill billions more in India/Pakistan/Iran/Russia etc. Breaking MAD would doom humanity to extinction.
I actually agree with you that it would be necessary to retaliate, but saying shit like "yes the children do deserve it" is vile. It's would be a necessary evil to prevent the Western world, and especially the US, from feeling they could annihilate whomever they want.
Hopefully nobody ever has to make such a decision.
I grew up with these children. All the IOF soldiers we see acting like complete sociopaths are around 18yos. These people were children only a couple months ago. If the genocide in Palestine is how westerners act when nuclear powers like NK /Iran openly oppose them, can you imagine the depravity they will engage in when there is absolutely no threat to them?
Yeah, the genocide that "israel" is perpetrating is awful. It's terrible what you can get your population to do when you dehumanize your enemies enough that your people think that the enemy's children deserve to die.
Again, I'm not saying that the west isn't dangerous or that a nuclear strike could be left without response, I'm saying that if you think that children deserve to die, you need to reassess, because that's a disgusting thing to believe.
To quote Che Guevara:
At the risk of seeming ridiculous, let me say that the true revolutionary is guided by a great feeling of love. It is impossible to think of a genuine revolutionary lacking this quality.
You can't be guided by love if you thirst for the murder of children.
normally i hate this kind of white room nerdlording, but in all cynicism, the widely broadcast and exceedingly graphic genocide of 33k civilians in the geostrategic backwater of palestine has netted us 1 aaron bushnell.
discounting the fact that nuclear genocide of the chinese would not be nearly so publicized nor evocative given their status as a peer competitor and ideological enemy (not to mention the means of extermination), in the current best case scenario we'd have 42k bushnells for 1.4b chinese.
42k is not a small number by any means, but i am uncertain of the effectiveness of such a group given that their only trump card is being white while their opponent is a regime that just glassed an entire country.
edit: maybe 82k actually, i remembered that one lady in atlanta
I'm just not sure what you're trying to argue here?
It sounds like maybe you're arguing that the American people wouldn't rise up and destroy the nuclear genocide perpetrating American government and therefore it would be necessary to do a retaliatory nuclear strike?
If so there's no need for argument, because I fully agree.
My point of contention with Oregoncom was that that he claimed that in fact, American children, deserved to be killed in a nuclear blast because some of them are racist. This is laying moral judgement on children who had nothing to do with the hypothetical first strike. This is fucked up.
No child ever deserves to be killed and I'm honestly fucking disgusted that that statement is getting so much pushback here.
it's not so much about what the citizens of a country "deserve" as about stopping the US government. i think the future for humanity is brighter if the US government is destroyed in global nuclear war than if they were just allowed to use nukes at will and no one was willing to stop them.
just aim all of your nukes at washington or wherever else the ghouls keep their doomsday bunkers. you have to retaliate in some manner or america will just successfully take the entire planet as its nuclear hostage. imagine the belgian congo but across the whole planet for at least a few decades if not centuries or millenia, and assisted by modern military and surveillance technology, and with no hope of resistance due to the nuclear trump card. don't give america all your money? get nuked. give in to their demands? now they can afford more cops to brutalize you and more drones and etc. to watch and control you. The question then boils down to whether you think extinction/death is better than eternal fascism. once a hypothetical competent america achieves nuclear-based economic, political, and military dominance, there will be nothing stopping them from enforcing racist eugenics programs at best and genetic engineering at worst to design their own twisted caste system, doing their best to manufacture the perfect workers and consumers, the most obedient population possible. think something along the lines of reproductively sterilized, disposeable workers with cranial bomb and tracking devices installed at birth to ensure compliance with any orders. america would also have a monopoly on the resources to attempt space travel. if this is successful, this fascist techno-dystopian america will be the only 'humanity' that spreads to the stars, any non-edited humans being genocided into extinction by this point, not hard given total global military dominance and air superiority and manufacturing control enabled by this hypothetical nuclear houdini america's inevitable extortion of every other country's resources and wealth.
Hot take: revenge is not an entirely useless thing. It shows everyone you have the capability to retaliate when you are wronged. If you don't do revenge some will think they can wrong you as much as they want which might create future situations of you being wronged again. And on the wrongdoer side, you cripple their ability to do same again or punish them so they don't it again. Send nukes so that remaining people can live
No, because the amount of nuclear firepower needed to kill 90% of China's population would be enough to generate firestorms that would doom humanity to mass starvation.
China should not give the Americans the mercy of a quick nuclear death.
Mao actually said that in a nuclear exchange, even if half of the world’s population is dead (2.7 billion at the time), then as long as the imperialist states are dead, and if the world’s socialist states could prevail, in a number of years the world will still re-populate to 2.7 billion people anyway. You might be on to something.
People all over the world are now discussing whether a third world war will break out. On this question, too, we must be mentally prepared and do some analysis. We stand firmly for peace and against war. However, if the imperialists insist on unleashing another war, we should not be afraid of it. Our attitude on this question is the same as our attitude towards any disturbance: first, we are against it; second, we are not afraid of it. The First World War was followed by the birth of the Soviet Union with a population of 200 million. The Second World War was followed by the emergence of the socialist camp with a combined population of 900 million. If the imperialists insist on launching a third world war, it is certain that several hundred million more will turn to socialism, and then there will not be much room left on earth for the imperialists; it is also likely that the whole structure of imperialism will utterly collapse.
If America had launched a first strike against China that will wipe out 90% of its population, should China retaliate?
It's not a case of "should". The PRC will retaliate with nuclear force should any country armed with nuclear weapons do the unthinkable against the PRC.
This is the PRC's nuclear deterrence policy.
Communists must not be pacifists because mercy does not exist for us. Peace and prosperity is our desire and the world's desire, and any attempt to spoil it must be crushed ruthlessly.
Stated policy is irrelevant once the missiles are in the air.
China needs to say that they'll retaliate, because that's the deterrent, but if deterrent has already failed then we can start thinking about whether China should retaliate, because retaliation really achieves nothing materially beyond revenge at that point.
You literally did say that China will retaliate. You made no mention of the possible difference between policy and practice, which I thought was interesting enough to introduce to the discussion. Why are you being so hostile? There's absolutely no need for it.
What does hope have to do with it? Either they do or they don’t. Our path to a future for humanity runs through mass organising and dismantling imperialism either way
Honestly I love how the book played me like a fiddle there lol. The whole time I was on the side of the protagonist that if people are less likely to respond it will help reduce the tensions with the Trisolarians and potentially avoid the conflict. Then as soon as the attack happened and the author explained that a MAD doctrine works only if both sides are ready to push the button and thus the only way to minimize casualties is by being prepared to kill everyone, it all suddenly made sense
Before nuclear Holocaust is unleashed it is necessary for their deterrence to work, and arguably the only moral choice, to have no disambiguity whatsoever. Everybody needs to be painfully aware that you will retaliate in full force in the case of a nuclear attack. You preferably need something like the Russian Dead Hand system, ensuring that you will retaliate even from beyond the grave.
If the Americans gets just a tiny hope that they can do a nuclear attack without being destroyed themselves the risk of them doing so increases dramatically.
But that everything changes once the first volley of nukes are flying. At that point your deterrence obviously didn't work and you're toast no matter what. Humanity as a whole is going to have an extremely hard time as a result of the American attack. Retaliating at this point would only serve as vengeance and add untold misery on top of the already unfolding cataclysm. The moral case for pushing the button at that time is much weaker. Personally I come out in favour of not doing it.
So in essence, the best position is the impossible position of fully believing in and preparing for retaliation but not actually doing it if push comes to shove.
The world is is kind of fucked either way. If MAD has broken down and the nukes are actually flying the entire planet will be destabilized as various environmental systems break down. More nukes don't help and I can't in good conscience say that I should make the decision or know what would be best for humanities future. The capitalist empire can't really sustain itself either way if nuclear hellfire has scarred and destroyed the world. There would only be global hatred for the Americans if they nuke the chinese like that.
I can understand both decisions from the Chinese though. It would only be fair, after all, for the chinese to retaliate.
Here's a tweak: based on what we know about America's antique nuclear ICBMs, if America attempted to launch a first strike and a significant portion of the launches failed in mid-air and the majority of the rest were intercepted by China's defenses (I assume they're working on if not already have hypersonic interceptor missiles), should China retaliate?
I would say the answer to both your and my hypothetical situation is yes.
My first reaction was to say that, despite it being an incredibly bitterly pill to swallow, the coldly rational choice is to do nothing.
I’ve been trying to work out how this isn’t the case, but so far haven’t figured it out. To do nothing is so unsatisfying. It’s exactly the kind of response someone like Gorbachev would have. But ending all life on earth, if that is the outcome, closes all doors. If you are ending humanity, then the nuclear response is ultimately pointless revenge. I suppose if you relax that assumption some - that there’s still a remnant of humanity that carries on - then I might agree with what zed says about how you are just leaving humanity in horrible position if you don’t respond. Where the US acts with impunity and starts dropping nukes like the US imposes sanctions today. Because if we’re talking about actual Americans… there’s no way most Americans will even flinch at killing hundreds of millions of people they think “deserved it”. This will not lead to some mea culpa on the part of America where they decide to build a better world and are ashamed of what they did.
The point of a second strike isn't to get revenge. The point of a second strike is to prevent a first strike. But if the first strike has already happened, hasn't the second strike already failed? If so, what's the point of launching it?
But the first strike is only launched when there is no fear of a second strike. If American intelligence finds out that Chinese nuclear commanders would not actually launch a second strike, you can bet your ass we begin bombing in five minutes.
If American intelligence finds out that Chinese nuclear commanders would not actually launch a second strike, you can bet your ass we begin bombing in five minutes.
They'll never know for sure though, so MAD still works. Honestly a country could explicitly state "we will not fire back" (as Jeremy Corbyn kinda did) and MAD still functions. You can't roll the dice on existential issues like that.
They'll never know for sure though, so MAD still works. Honestly a country could explicitly state "we will not fire back" (as Jeremy Corbyn kinda did) and MAD still functions.
I think it's pretty clear that if your country is going through a pacifist movement of self-disarmament, you will not be able to return a second strike.
Political leaders can say whatever they want in times of peace. Once the nuclear powers are at each other's throats, nuclear pacifist rhetoric becomes dangerous. Imagine if there was a nuclear pacifist movement in the USSR that was succeeding during a time of high tensions. Khrushchev says that the USSR would not return a second strike if the USA nukes them first. Bombing would've begun in five minutes.
You can't roll the dice on existential issues like that.
If they're verifiably getting rid of their warheads, sure, but otherwise? What if leaders have a change of heart in the moment? What if military leaders have hidden access to weaponry even if civilian leadership disagrees? What if a display of pacifism is actually just a weird ruse?
What if a display of pacifism is actually just a weird ruse?
What on earth are you supposed to gain from this? There is literally nothing to be gained from doing this. This is like trying to convince the (imperfect) predictor in Newcomb's paradox that you will pick both boxes, and then only picking box B. Box B is empty, and you have played yourself.
At what odds are you rolling the dice?
Do not underestimate the bloodthirstiness of American leaders. Douglas MacArthur infamously wanted to nuke China during the Korean war.
China didn't have their own nukes during the Korean war. Obviously there were external factors in play that will have influenced things () but there wasn't one-on-one MAD between the US and China/Korea.
There's nothing to be gained, I'm just saying that MAD still functions.
As I said elsewhere, Corbyn during a debate basically said he wouldn't retaliate to a nuclear strike; people were really mad and called him a threat to national security but I really don't think his stated intentions ever really mattered because you can never judge how legitimately he'll stick to those statements once shit hits the fan.
Yeah it’s a difficult one for sure. If a billion Chinese people were killed by reckless Biden/Trump’s decision, the American people wouldn’t do anything at all? That’s bleak… but it’s not unprecedented with the atomic bombing in Japan.
To say they would do nothing at all was probably an exaggeration on my part. When you’re an American, and you have grown up seeing how little your fellow Americans care about deaths in places like Iraq and Gaza, it’s hard not to become cynical.
There are more than 2 countries. There are also chinese survivors. If america is not nuked it will be very bad fo both those grpups. And very good for americans. Because of this there is no paradox or moral conundrum. If you run a nation state, then your duty is to ensure the best outcome for your realm's people; maybe its more rational to not only nuke the yanks but nuke everyone else so that history resets and the survivors of your side are not taken advantage of by countries that still have an intact industrial base.
If you don’t retaliate, that signals that you are ok with the US firing more missiles to kill off your remaining 10%. You don’t have the luxury of a choice. Isn’t this the core of MAD?
China should not retaliate, but the possibility they will is important to prevent the first strike in the first place.
Those saying that Americans need to "learn a lesson" in the event the US government performs a nuclear first strike are:
a) Condemning millions of people with no responsibility for that decision to death (including the millions of deaths that will occur outside the US due to fallout, ecosystem disruption, nuclear winter, supply chain disruption, etc)
b) Ignoring the fact that nuking China would already be incredibly destructive for the US due to economic implications alone
c) Assuming that the people in charge of launching any future US nuclear strikes are going to be meaningfully affected by that kind of "lesson" in a way that shifts policy towards peace. Remember, these are the people who will vanish into classified doomsday bunkers if things actually get hot. Are they really going to have second thoughts on further nuclear strikes because of a Chinese response? Or, with the nuclear cat out of the bag, will they decide to just go ahead and go scorched earth against their enemies in hopes of a Pyrrhic victory?
Using a nuclear weapon is never morally justified, including in retaliation. Trying to paint incinerating millions of children as the moral course of action because you think it might hypothetically lead to a better future somewhere down the road is pretty silly.
It would almost certainly happen anyway, because second strike policy needs to be credible to function as a deterrent, but the actual moral choice would be not to.
