I think there is a difference between our lines of thinking.
I believe that maintaining equal MAD/MV and ensuring MAD/MV is the fundamental basis of all other strategies that China may pursue.
When has China ever had have equal MAD against the US? How can it be the fundamental basis of all other strategies when China never before had that capability?
China is expanding its nuclear deterrent because it feels minimal credible deterrence is no longer sufficient to guarantee deterrence. However, there is a massive spectrum between minimum credible deterrence and guarantee MAD, and frankly I don’t think you need full MAD to be able to effectively deter the US from reckless nuclear adventurism.
That is to say that while I am no longer confident that the answer will always be ‘no’ if the US is asked if it is worth it to trade LA for China; I do think that it is not unreasonable to think that the answer will remain always ‘no’ when the price is higher but still far lower than ‘the destruction of every American city’. Precisely how many American cities is too many will be a matter of fierce debate and will probably be a moving target that increases as Chinese national power does. However, right now and for the next generation at least, I find it hard to believe any US leader would accept the destruction of the top 100 US cities. Which is basically what China’s new silo fields should be able to achieve, even with BMD and a US first strike.
In that sense, it absolutely makes sense to put its best card (i.e.: IC-HGV) in a mission where maintaining MAD/MV is its initial, most important primary role.
Once they are capable of maintaining that MAD/MV, then other missions for the IC-HGV can gradually open up as the strategic and geopolitical environment requires it.
The problem is that if you start off with it in a nuclear role, you effectively taint it with that role. Thereby massively increase the risks of misunderstandings if and when you do use them in a conventional role.
If the other side says they consider any use of IC-HGVs as a nuclear first strike even after you said you removed the nuclear warheads from them, it puts pressure and risk on you for when you want to actual use these in a conventional way.
Sure, you can always call their bluff, but when the costs of getting it wrong are so high, do you really want to increase the risks by even the smallest bit?
I've been fairly consistent in saying I believe the primary and most important role of the IC-HGV is to ensure and guarantee MAD/MV.
And I have always said that it was not needed to archived guaranteed MAD.
China’s new silo fields alone would be more than enough to achieve MAD against existing US BMD. Unless and until the US starts to build new BMD interceptor fields with thousands of interceptors, China doesn’t need anything more to achieve MAD. H20 and 096s are the back ups and safety margin. Throwing IC-HGVs into that mix is just massive overkill and a waste of China’s only conventional strike option against CONUS targets
I cannot see how the conditions and prerequisites for the PLA to be willing to use those weapons is not equally as important as being willing to use those weapons or even possessing those weapons in the first place.
They are important, but frankly immaterial to the nature of this debate. I see IC-HGVs as being used as deterrence and retaliation weapons against the US trying to use the cover of any military conflict to cause damage to China’s civilian infrastructure that fall well short of China’s nuclear retaliation threshold, as has been every clearly and precisely spelled out in its NFU policy.
The precise trigger point for their use is not relevant to the argument that they should be used for conventional strike as opposed to being relegated to the strategic nuclear arsenal, where to be frank, they will never ever be actually used, because that’s the best and only sane outcome when it comes to nuclear weapons.
I expect the new ICBM fields may reach near full intended capacity in 10 years, I expect initial operationalized IC-HGVs to enter service in limited numbers perhaps in 5-8 years.
I expect reliable MAD/MV to be attained in 10-15 years.
By procuring a limited number of IC-HGVs that are technologically mature, they are capable of ensuring MAD and pre-empting any systems that the US may pursue to provide a more hard counter to PLA ICBMs and placing equivalent MAD/MV into doubt.
Good, our timeline expectations are not wildly off. But I think where we differ is in what is needed to achieve effective deterrence, how important that is and future proofing priorities.
While you seem to think only guaranteed full MAD will do, and needs to be achieved today. I just don’t see it. Far from it in fact.
China is not really threatening anything expect American homogeny. It makes zero sense for America to launch a nuclear war of pure choice against China to preserve US homogeny only to come out with a handful of cities still not glassed.
Nuclear war against China only makes sense for America if it comes out of it with China destroyed but America still the most powerful country on the planet. Loosing LA would be acceptable, loosing even the top 10 US cities would not.
As for future proofing, well as I said, that is what the H20 and 096 SSBNs are for. With more silo fields always an option.
Unless and until the US starts to massively expanded its BMD capabilities in proportion to the size and scale of China’s silo field increase, BMD is an irrelevance given the scale of China’s conventional nuclear expansion.
And to be frank, even if China wants to use IC-HGVs for nuclear delivery, it would still makes absolute sense for China start with them as conventional only. Because it is in China’s best interest to want the US to massively expand its BMD because that is an arms race that massively favours China, and because Chinese IC-HGVs will totally invalidate US BMD, so they more resources they sink into that the better.
For strategic weapons systems, foreign intelligence/military reports are actually not a bad metric.
Least bad =\= good.
That, with a combination of Chinese credible rumour sources +/- state media hints, give us a fair assessment -- and is also the same way we currently use to assess Chinese strategic weapons systems readiness.
And what state media hints have been given that IC-HGV will be nuclear armed?
