The recent news about China's nuclear advancements has encouraged me to collect some thoughts on these developments and put them into a broader strategic framework. I think many of us here felt that this expansion was long overdue, but I didn't appreciate just how much it would improve China's overall position until I thought more deeply about the matter.

First, I'd like to stress that this buildup is very real. Any talk about "wind farms" (other than East Wind farms) or "the Pentagon is just lying to fundraise" and you can see yourself out of my thread. That's useful disinformation to spread around social media, but it has no place in a serious analysis. To anyone who thinks otherwise, I can only recommend that you follow the ethos of the successful drug dealer: never get high on your own supply.

With that out of the way, I'd like to examine the first and most obvious strategic implication: The impossibility of a large American first strike that relies on missile defense to neutralize the surviving remnants launched in retaliation. Having three large fields of missile silos ready to launch at a moment's notice and completing the necessary early warning systems - primarily ground-based radars and infra-red monitoring satellites - means that any first strike won't have the chance to land before China launches a retaliation so obliterating that it deletes the US from existence. If we are thinking about the escalation ladder in a conflict, China has just matched the US at the highest rung of that ladder and removed any option America had of climbing to that rung.

This in and of itself is a very salutary development; by expanding and improving its arsenal, China has stopped the US from posing an existential threat to it. But there are far subtler benefits to be had than just securing China's survival - as I just mentioned, by filling the gap at the highest rung of the escalation ladder, China has removed from the US the option of climbing to that rung. Let's extend that idea and fill the gaps China has in its escalation ladder from the top down...

While the ICBM silos and Mach 20+ hypersonic glide vehicle tests are well-attested, what follows is mostly my own speculation (although still backed by evidence). Suppose China doesn't just improve its strategic arsenal, but expands and improves its tactical nuclear weapons as well. There have been some indications that it's doing this already - namely the dual nuclear/conventional precision strike role for the DF-26 IRBM. This would match the US's tactical nuclear weapons rung of the escalation ladder, which it would be tempted to escalate to if it's losing a conventional conflict. Having a robust tactical nuclear weapons arsenal gives symmetric responses to China should the US escalate to that level, which precisely ensures that it won't.

An important principle to note here is that freezing the US out from escalation to a certain level on the ladder actually opens up coercive options for China at the levels below it. Having a robust, numerous, and diverse nuclear arsenal allows China freedom of action at the conventional level of conflict, free from the fear that the US might escalate to a nuclear level where China would have no response. This technological advancement would even allow China to deter purely conventional attacks on its homeland (for example, bombardment of its military-industrial infrastructure) by threatening asymmetric tactical nuclear strikes on similar US targets. For example, a very accurate HGV armed with a one kiloton nuclear device (very small by nuclear weapons' standards) fired at a US shipyard following a US attack on a Chinese shipyard would destroy the US shipyard without annihilating the city it's in. I foresee a much expanded role for such tactical nuclear warfighting in Chinese military doctrine in the decades to come.

Now, I imagine that at least some readers would have their hackles raised by this. A (albeit small) nuclear first strike on the US homeland? My response to this objection is that we ought not to be too fixated on the physics of the weapons involved and instead look at the more pertinent factor: the scale of devastation. A one kiloton detonation is around the scale of the Beirut Explosion; do you know how many people died in the Beirut Explosion? 218. By contrast, consider how many people would die in a conventional attack that destroyed the Three Gorges Dam. The relevant principle that should guide China's decision on striking the continental US is a simple one: equality of devastation. If the US wants its homeland untouched, what it must do is very simple - extend China the same courtesy.

While operationally extremely provocative, such a doctrine is (perhaps paradoxically) strategically reactive.

Another mission to consider for the ostensible tac-nuke armed HGV (and future Chinese systems like the H-20 stealth bomber) is strikes against the US's missile defense infrastructure. It's often noted that the test record of missile defense systems against ICBMs is spotty at best and that a sophisticated adversary could easily overcome it. Be that as it may, US decisionmakers believe that their missile defense works and so might contemplate escalation based on the false assumption that they are protected from retaliation. That delusion is a dangerous one for them to entertain, hence they should be promptly disabused of it in a serious crisis.

What would the cumulative effect of China closing the gaps in its escalation ladder from the top down as I've outlined be? First, as I've already mentioned, greatly expanded freedom of action at the conventional level. Second, the psychological impact of such a stark change in the balance of power on US allies will be wrenching. The decision a country like Japan would make in joining the US in a conflict (or even maintaining a formal alliance) depends ultimately on considerations of its own survival - nobody is going to tag along with the US on a suicide mission. A US ally like Japan understands that if the US can't escalate to the nuclear level to protect it, China could maul it solely with conventional weapons and the US would have no response. Countries throughout the western Pacific would start to see a security relationship with the US as an ever increasing liability, and it would not escape their notice that the US can ultimately leave the region while they can't. Third, China's conventional buildup has reached such a point that the US is seriously contemplating losing a conflict. What usually happened historically when a state perceived its position so dramatically weakening was it launched a war out of desperation and "now or never" thinking. An expanded Chinese nuclear arsenal and the credible threat of its use prevents the US from launching such a war.

Having said this, I don't believe that a war with Taiwan is imminent or even likely in the next decade or two. The primary reason is that while a nuclear expansion solves the problems of vertical escalation China has, it doesn't address the problems of horizontal escalation. The US has options beyond direct military attacks against China - for instance, it can blockade Chinese shipping or disconnect China from the dollar trading system. These problems require different (and much slower) solutions that I'll touch on here. China can neutralize the threat of blockades by expanding the PLAN (most crucially, the nuclear attack submarine fleet) and basing it in friendly countries along its sea lanes. I have in mind specifically Cambodia and Pakistan, and perhaps others like Myanmar, Iran, and Syria. The problem of trade sanctions can be resolved by developing China's interbank payment system CIPS and its central bank digital currency. More importantly, strategies like dual circulation would reduce and eventually eliminate China's vulnerability to foreign technology, and carbon neutrality would obviate the need for hydrocarbon imports.

Overall, a very significant development that augurs greater things to come.

Tactical nuclear weapons is the way to go. Recently they have already put some tactical nukes on the Ohio class submarines for possible scenarios with Russia and China also using tactical nukes. Wouldn't be surprise to see tactical nukes as well as conventional in future IRBMs and HGVs in U.S. platforms when they deploy them in the Pacific especially Guam to contain PLAN.

You need to take the word "contain" out of your vocabulary. The best you can hope for in the future is that you have some means of self defence for a place like Guam. If you base nuclear weapons there then prepare to have it turned into a puddle of molten glass.

Anyone that thinks 300-1000 nukes provide anything more than a political deterrent is kidding themselves.

The United States thought that they needed at least 40,000 nukes to even achieve MAD parity with the Soviet Union and the Soviet Union thought they needed at least 50,000 nukes to even achieve MAD parity with the United States.

Do yourself a favor and plot out the entire nuclear arsenal that you think a country has on nukemap and see how few things you can actually destroy.

China's 300-1000 nukes was obviously sized to be a political deterrent to Soviet first strike and nothing more.

China's primary deterrence against U.S. first strike is Russia.

If/When the U.S. successfully color revolutions first Belarus and then Russia (and possibly Iran), that deterrence is gone and the U.S. will obviously launch a first strike on China as soon as possible.

This is why it's obvious that all sides are bluffing when they talk about a "great power war".

First, there isn't anywhere near enough stockpiled and/or production capacity for any of the advanced weapons that any major power has to last for more than a few weeks or months at most of war.

Second, there isn't sufficient general population bunker capacity to even save the cream of the crop top 10% of societies that will be difficult to replace afterwards.

Add that to the fact that the United States has cities that are (un)planned to be so spread out and with so many redundant road transport links that they are hilariously resilient to any sort of bombardment.

One should also acknowledge that it takes at least 30% population destruction before the will of a population breaks through kinetic conflict.

300 ICBM silos (according to the satellite images released by USA; not sure if there are other new silo sites are not found yet) in construction in parallel is not seen in the human history before. This is obviously not something could be done in just one night, but need very detailed planning and long time in implementation. I guess the whole project was started four to five years before.

So what kind of incident could trigger the Chinese leadership to make such an unusual decision?

Obviously the madness showcased by Trump administration is completely changing Chinese government's assessment on a potential nuclear war with USA. So China needs to do something to protect itself.

There is no need for any use of nuclear weapons at the tactical level. In the past, the accuracy of long-range firepower has been inadequate, requiring the use of several thousand tons of bombs or a single tactical nuclear weapon. Modern precision weapons can miss the target by no more than five meters. Using nuclear weapons on tactical missiles would only make it harder to use tactical missiles, since the primary goal is to prevent the other side from miscalculating and triggering a nuclear counterattack.

The Never Reported Lot

When we talk about a credible 2nd strike on US soil, it refers primarily to TEL-based ICBM (e.g. DF-31/41), sea-based SLBM (JL-2/3) and such, these are developed from 1990's onward, some even are post-2010's. They carry MIRV warheads, i.e. low yields, in large quantities. For whatever reason, this stockpile has never been included in any reports by NTI, ICNND, FAS or others. Why this stockpile gone "missing"? I don't know, but based on size of current active duty I estimate at least 1000 deployed by now, yield range 150-500 kt, that means a total firepower of 300+ megaton never reported by anyone.

The Decades Old Advertisement

Now come to the stockpile which did get "advertised" by the west for decades, those silo-based ICBMs. As per the "advertisement" here are 240 warheads, each yield 3.3 megaton (earliest model), total firepower 294 megaton or roughly half of US total (see above chart). One warhead here can deliver 2.78 million fatalities + 4.3 million injuries to a city like New York at time of blast, fallout effects not included. Perhaps firepower of this stockpile is already more than adequate to annihilate entire US, so western propaganda decided to "freeze" China's stockpile at this 1990 level? Alright, but for decades? Anyway from China's perspective, some features of silo-based liquid-fuel ICBM deem it not fit for 2nd strike doctrine, that's why China develops new stockpile as mentioned in paragraph above, the "never reported" lot. Have China abandoned silo-based ICBMs? Obviously not the case, their continuous existence serves as an option on the table if NFU diplomacy fails. Moreover with new techs like FOBS or HGV and such maturing these days, silo-based ICBM could become effective strike weapons once again. I believe some DF-5 will replace payload of 3.3 megaton warhead with newer 5 megaton model, some will be converted to DF-5B carrying MIRV warheads (8~12 per missile) of lower yields, and some used for FOBS+HGV.

You are forgetting that in a first strike scenario, the country that launches the first strike can easily mitigate any nuclear retaliation by simply having enough bunkers for the 10% of the population that is less easily replaceable.

You also forget that one cannot use all of one's meager nukes on counter-value strikes as counter-value strikes do nothing to stop a subsequent ground invasion.

What you have presented is simply a political deterrence, not MAD.

1000 nukes, even if all 5 megaton, will do negligible long term damage to the United States even if 100% of them hit their intended targets perfectly.

Those nukes get wasted as counter-value, and then the United States uses their nukes on counter-force and gets a checkmate.

This is why the vast majority of nukes in the U.S. vs Soviet standoff were tasked to counter-force.

That's exactly what I said. Other than building the more "flexible" 2nd strike force in recent decades, in parallel China has been refurnishing weaponry exclusive for 1st strike, namely the silo-based ICBM, with new ABM penetration techs. In fact China even seems to be picking up momentum in expanding this 1st strike exclusive force. The rationale of doing so is exactly like what you've mentioned: NFU (No First Use) diplomacy, which is a war deterrence, may fail has to go for 1st strike. In fact there's another scenario that also prompts the use of 1st strike: when China has enough confidence in launching unstoppable strikes while at the same time possess capability to neutralize all incoming threats, i.e. no MAD but unilateral destruction of US. You're right, I don't see much of US population can survive China's 2nd strike, let alone 1st strike. Ground invasion will clear the rest.

You don't seem to get it.

If the military is still intact and relatively untouched after the said "first strike," the power on the receiving end can easily use their arsenal to destroy the force of the opponent in a land invasion by using their nukes in a counter-force move.

Aka, this means one can easily win after someone "counter-value" first strikes you.

This means counter-value is a worthless tactic in the real world.

After your edit it's clear you are simply a propaganda bot instead of someone that knows anything about nuclear strategy.

You all repeat the same thing no matter how obviously wrong it is in nuclear strategy.

I'm done wasting my time talking to someone that will never understand.

Shall I rephrase so you get the picture. If NFU diplomacy fails, China will initiate 1st strike when she has enough confidence that the strikes are unstoppable while at the same time possess capability to neutralize all incoming threats, including from whatever US military capability that might have survived the 1st strike. Large bombs say 3.3-5 tons are city busters, while more accurate weapons would be used on hard targets, bunkers.

After US cities and much of population gone, whatever US military left have already lost their supply chain to stop a ground invasion, not to mention they have already lost most important meanings of life - their families.
