There will be a certain end state reached by each side of the conflict, that each side must subsequently recover from.

In the above-described exchange, China clearly has a far better chance of recovering in a shorter time than India does. Recovery to status quo ante bellum may take a very long time
This is an accurate interpretation of what I had in my mind when I suggested that scenario.
What you have done in writing the words I have quoted is to conceive of life after failure of deterrence. That is, China has failed to deter India and India has failed to deter China and they have both done their darndest and after that there is some life left and that after-life would be better for China because China is capable of inflicting far more damage on India than India on China.
So what you are talking about is life after failure of deterrence, and not deterrence per se. But this is a valid thought process IMO but I must point out that there is a difference. Nuclear Deterrence is the possibility of avoiding getting hit by the other guy's nukes. It gives no guarantee that there will be no conventional warfare. The minute the other guy's nukes hit you, your deterrence has failed.
So if China nukes India, India's deterrence has failed
And if India nukes China in retaliation, China's deterrent has failed.
Shiv,
No argument there. The corollary of what you describe is that "deterrence" itself is a side-effect, a meta-consequence of arming for nuclear war. In the final analysis there is only a given probability of war, and the probability that when one side uses nuclear weapons, it becomes a nuclear war. The fact of one or both sides of a conflict having the capacity to deploy nuclear weapons, confers (as ONE of its effects) a certain additional probability that military confrontation will be avoided or curtailed for fear of nuclear devastation if it escalates too steeply. Deterrence is nothing but a name for this additional probability effect.
Deterrence is not an "end" in itself, and we mustn't allow the prevalent rhetoric to convince us that it really is one. Nuclear weapons are developed so as to be able to cause pain of a certain order of magnitude to the enemy. Governments, politicians and diplomats like to use the politically correct term "deterrent" for this capacity, because it sounds a lot more polite than "major body count extractor"... just as "friendly fire" is used in place of "shooting one's own soldiers in the back."
The question of life after nuclear war and the idea of whether my life is going to recover faster and better than the other party's life is fundamentally an acknowledgement that my own nuclear deterrent may fail - that is, my nuclear deterrent did not deter. Of what use are China's 500 odd megaton size nuclear warheads as a deterrent, or for that matter any size of deterrent if that deterrence is going to fail and one must prepare for life after failure of deterrence.
Given that deterrence is only one probabilistic effect connecting the two probabilities of life before nuclear exchange and life after nuclear exchange, no one should construe it as a guarantee of any kind. Forget nuclear weapons for a moment. In a tribe of cavemen, consider the one caveman who gets his hands on the biggest available mammoth-femur to use as a club. That confers some "deterrence" but no guarantee that the caveman has nothing to fear from his fellows. They can still cut his throat while he is sleeping, or sneak up on him from behind, or any of a number of things. In the end it is the cause of conflict and the effect of conflict that are immensely more important, and the "deterrent" femur is important only to the extent that it influences either of those states. If somebody attacks the caveman and kills him despite his femur-club, the last thing he will be worried about in his dying moments is that his "deterrent" failed. That is of no more consequence than a pathologist's report of what precise type of injury was the cause of his death.
This does not, however, negate the fact that another caveman deciding whether or not to challenge the first caveman in a hand-to-hand fight, would have to factor in the size of the femur-club in the first caveman's hand. The size of that club might change the mind of a potential attacker in a given instance. It is only to that extent that it has value as a "deterrent." This is a certain finite value, potentially a measurable value that is directly determined by how big, mean and sharp-edged the club is.
Now that doesn't mean that a caveman shouldn't try to get his hands on the biggest, meanest available mammoth-femur for use as a club, thinking "oh, this may not be that big a femur but it can still hurt someone." It does, however, mean that the "deterrent" value of his club isn't enough to serve as a sole guarantor of safety.
Having the biggest possible deterrent is then an absolutely necessary condition, but by no means a sufficient condition to achieve permanent security and peace of mind.
In fact once deterrence fails, the life of your nation is independent of the numbers and megatonnage of your own nuclear weapons but wholly dependent on the size of the other person's nuclear arsenal. If the other guys weapons are puny, your nations will suffer less and if the other guys arsenal is huge, your nation will suffer more. Suffering and pain is guaranteed either way, and even if you have 5000 weapons of 1 megaton each and are ready to turn the other party into a glass parking lot the amount of damage you receive depends on the other guy's capability.
Yes, of course. That is the nature of any purely offensive weapon. No sword ever served as a suit of armour, and no gun ever made its owner bullet-proof. Still, a sharper sword or a bigger gun means you have a stronger capacity to inflict damage. A blow from his smaller sword, while still harmful, might only cause a relatively superficial wound that you may eventually recover from. A blow from your sword, however, could cut off his head or a limb at one stroke. The argument that it is better to have a sharper/bigger sword holds true, regardless of the purely "deterrent" value of having such a sword.
If you feel that the other guy's capability is weak and that the other guy has only 50 bombs of 10 kilotons then you may feel that you are ready to take that much damage. But if you look at the other guys arsenal and find that it is 500 bombs of 1 megaton you may tell yourself "Hey I would be willing to take 50 bombs of 10 kilotons but not 500 bombs of 1 megaton each"
Absolutely. I don't know about specific numbers but I am sure the guys who plan nuclear warfare contingencies make these sorts of cold calculations all the time. Mao for a long time felt that America could be challenged and confronted militarily because even the loss of 50 million Chinese citizens to American nukes would still leave him with a larger population than most countries. He had already begun to think about recovery after an American nuclear attack in 1951, and decided the risk was worth it to intervene in Korea. Had he not thought like that, he might never have challenged America in the Korean war. America's nuclear arsenal was thus useless as a "deterrent" against Chinese aggression in Korea; but, had the Americans actually decided to use nukes in Korea, they would still have been plenty useful in terms of inflicting damage on the PLA!
Similarly in 1971, an India without nukes went on decimating the TSPA in Bangladesh even as a US carrier battle group with nukes was menacing us in the Bay of Bengal. How many megatons of nukes was the Enterprise carrying, and what damage could they have done if they fell on Kolkata or Bhubhaneshwar or Madras? Definitely somebody somewhere in IG's cabinet was deputed to figure those things out, alongside other experts in political diplomacy who were assigned to figure out if Nixon was bluffing. The sum total of factoring in all those equations came out to a negligible probability of India being harmed by the US before Dacca fell. It was guesswork of course, but it turned out to be the correct guess. The rest is history.
I believe that what you are suggesting is that India is looking at China and saying "Hey we are not ready to take 500 bombs of 1 megaton each" but you believe that China is looking at India and thinking "Hey we are ready to take India's puny 50 bombs of 10 kilotons, so let us provoke India". I believe that what you are suggesting is that China is not afraid of India's puny arsenal and should be made afraid so that they should say "Hey we were not scared of India's puny 50x10kt warheads, but now we are scared of India's 1000 one megaton warheads and we will stop provoking India in future". I do not find this an argument that reduces my fears in any way. I cannot see how an increase in my arsenal will reduce the pain I feel if I my country gets nuked by China.
Here is where I must beg to differ with you. I do not know for sure what the Chinese are thinking. I cannot know for sure what the Chinese are thinking.
My fear is not a factor here; I may be afraid of even one Chinese nuke, or I may say "ok, we can still come back after losing P,Q,R,S cities and T lakh people, and the risk of that is worth retaining the option to exercise X,Y,Z conventional countermeasures in the event of Chinese aggression in Arunachal/J&K." But that is irrelevant. In terms of developing my nuclear arsenal, I only want the Chinese to be as scared as I can make them, of what will happen if they send even one nuke. Therefore, I can only do everything in my power to maximize the probability that they will be scared. There is no way to do this other than by building enough nukes of enough yield to achieve a certain probability of inflicting a specific measurable quantum of damage against China.
As an armchair strategist I cannot calculate what that quantum of damage is, or how many nukes we will need to achieve it; but again, people with the expertise would be able to figure it out. What effect would X hits of Y kilotons have on China's industrial capacity? Economic capacity? Population resources? Natural resources? Financial institutions? Political stability? Infrastructure? Agriculture? Etc. Etc. In the absence of telepathy, it definitely involves some amount of guesswork to take the next step, i.e. to relate a specific quantum of nuclear warhead damage to a state that Beijing would consider impossible to recover from while maintaining political and/or territorial integrity. However, I'm sure there are people in India qualified to make very well educated guesses in that regard.
So our disagreement boils down to this. You appear to be saying that, even given the size and yield of our current nuclear arsenal, our experts have already determined that the capacity to inflict a threshold quantum of damage needed to scare the Chinese has been exceeded... hence, testing or developing bigger-yield nukes is not necessary. (Correct me if I'm wrong, but that appears to be the thrust of your argument.)
I am saying, I wish I could believe that. But I do not have faith in the government institutions that tell me (and in fact, do not even do a very clear job of telling me) that. What has shaken my faith in those institutions? Well, (1) the widely disparate nature of 1998 yield estimates made public by various government people, from Chidambaram ("S1 was 45 kT") to K. Subrahmanyan ("we have 80 kT") to K. Santhanam/ B. Karnad ("no more than 20 kT pure fission is assured".) And (2) the abject paucity of data...an essential part of arriving at any conclusions...which is a direct consequence of having ever done only one test. I'm enough of a scientist to be extremely skeptical of any conclusions when the data is so absurdly limited and the observations reported are so vastly diverse.
Given the general level of confidence in all spheres of governance, policymaking and security affairs that our current GOI inspires, I'm afraid I need more tests in order to feel confident in our nuclear arsenal's capacity to deliver the optimal quantum of damage to China.
We are already scared of China's nukes and Pakistans nukes. This question is only about what would scare them. We cannot stop being scared. Chinese and Pakistani nukes are not going to vanish if we get a bigger arsenal. So how would our fears become less if we get a bigger arsenal? Our fears remain exactly the same whether we have nukes or not. We can only hope that China and Pakistan are scared by us. What scares them is pure guesswork. How do you guess what scares them? You have already guessed that what we have does not scare them. At what stage in the development of our arsenal will they start getting scared and how would you assess that?
Of course we are not going to stop being scared to one extent or the other. Of course, China and Pakistan will not vanish by the fact of our getting a thousand 1 MT nukes. A deterrent, as I said, doesn't guarantee any of those things any more than the size of the mammoth-femur in hand guaranteed a caveman's security in all contingencies.
On the question of "pure guesswork", however, I disagree with you. There are people in New Delhi whom I believe are equipped to make very well-educated guesses about this. They have seen and measured the 1998 test in person, and are privy to the specifics of any new weapon designs developed since that time. They have inputs available regarding everything from the state of China's finances to the fate of current crop harvests in particular provinces to the magnitude and extent of internal dissent against the CPC at any given time. I would trust a consensus estimate made by these experts to the effect that our ability to inflict a certain quantum of damage could most likely cripple PRC beyond hope of recovery under its present national structure and political dispensation. Anything beyond that, I as a private citizen have to take on faith... just as I take on faith that our army is capable of defeating Pakistan in a conventional contest, or that our political leaders aren't pulling out of Siachen and handing over J&K to Pakistan tomorrow.
What bothers me is that those strategic analysts, appointed by our government to evaluate all available inputs and come up with the best guesses, as well as different scientists who were directly and personally involved with our bomb program, are openly contradicting each other about the damage-inducing capacity of our nuclear arsenal. They do not seem to have any consensus. They disagree publicly, and what is worse, they will not do the one thing that could eliminate any doubt and help to achieve a consensus... conduct more tests.
I may still be wrong. We could conduct more tests, prove 1 MT or 2 MT yields, prove MIRV capacity, and the Chinese could STILL keep trying to encroach on Tawang or deploy PLA troops along the LOC. But then, at least we will know that we've done everything in our power to maximize PRC's fears on the strategic weapons front, and this will give us some amount of valuable insight towards evaluating our other options.
