Needless to say, "minimal credible deterrence" from the 1980s no longer works today. Having the capability to lob 5 or 50 warheads at the enemy is completely different than having the capability to lob 500 warheads at the enemy. The enemy may be able to intercept all 5 or all 50 warheads, but can the enemy intercept all 500 warheads? That's called deterrence of proportionate response - And it's sorely needed in the present geopolitical climates in DC and Brussels, where more and more people are hallucinating that they are invincible against the "yellow peril of the 21st century".
Actually, this matter is quite simple.
In the 1970s-1980s, countries around the world were not far from the dangers of World War II. Politicians who experienced World War II were still present. Therefore, the minimum deterrence theory was not a problem. This theory mainly allowed opponents (essentially the United States and the Soviet Union) to weigh the costs of attacking China. In fact, the minimum deterrence theory is not just about maximizing the slaughter of the opponent's people to achieve retaliation and deter the opponent.
The premise of the minimum deterrence theory is that there are two mutually nuclear-balanced major powers. The effect of the minimum deterrence theory is not simply to kill the opponent, but to break the tacit understanding between two nuclear powers in mutual nuclear balance, allowing one nuclear power to be severely injured and helping another nuclear power to win.
There is an old Chinese saying: The mantis stalks the cicada, unaware of the oriole behind. Only those who can laugh until the last moment are truly victorious.
China's minimum nuclear deterrence theory actually tells any opponent that before my death, I have the ability to severely injure you, and then your real opponent will take advantage of your illness and take your life. This is the true purpose of China's nuclear strategy. We call it hijacking. It is another route outside of the alliance strategy. When small countries maneuver between major powers, the main strategy of the West (the former US-Soviet confrontation, now the US-Russia confrontation) is mainly that if you do not join me, you are my enemy. This alliance loses autonomy (look at the current US-European relationship). What China adopts is actually a strategy in Chinese culture that leverages others' strength but ensures its own (that is, not relying on any side, developing independently).
I must also mention that looking at issues from China's perspective, it can only be said that you do not have enough historical information (China is the country with a truly long-term cultural heritage). In our history, it has long been proven that the alliance strategy is actually useless, especially for major powers. The alliance strategy can actually accelerate the demise of powerful countries, with no benefits. This is the real reason why China never forms alliances. China has existed for thousands of years and has experienced multiple rounds of the rise and fall of major powers. Therefore, it is too clear that alliances are useless and only harmful to powerful countries, with no benefits.
Just look at the United States. In the ten years after the Cold War and the Gulf War, the United States was the most powerful country in the world. But what is it like now? The power of the United States is tottering. Why? It's because it maintains an alliance status to try to permanently solidify interests. But it's too naive. If you understand a little more history (China's), you will know that the alliance strategy is too consuming for imperial strength. If an empire wants to last longer and slow down the process of decline, it must reduce the unnecessary consumption of its own strength. And the result of an alliance is definitely the opposite.
The transformation of China's minimum nuclear deterrence strategy is actually something China has discovered long ago. After the Gulf War, nuclear deterrence gradually lost its power. In simpler terms, Western countries believe they are the end of history, the existence of high-tech weapons, and the form of proxy wars provide a conventional warfare means that can maximize the consumption of opponents and protect themselves. Ultimately, it reduces the power of nuclear deterrence. In fact, the problem Russia is facing now is this, the actual decline of nuclear deterrence. That's why NATO can continue to expand eastward. Finally, the Russia-Ukraine war broke out. Today's situation is that no matter how Russia says it will use nuclear strikes, it is impossible to suppress NATO's actual participation in the Russia-Ukraine war, directly confronting Russia on the front line. To put it bluntly, it is a bet that Russia does not dare to use nuclear weapons to attack NATO countries. Russia, which lacks nuclear deterrence capabilities, is actually just a medium-sized power, and Russia has a long border that cannot prevent opponents from infiltrating. That's why we have today's situation.
For China, the actual adjustment of the minimum nuclear deterrence strategy and increasing the stockpile of nuclear weapons is not because China's nuclear deterrence capabilities have been weakened (we know that many European and American countries have long forgotten that China is a nuclear country), but because the premise of the minimum nuclear deterrence strategy is the nuclear deterrence balance formed by leveraging the power between two nuclear powers. When Russia's nuclear deterrence is weakened, the premise of implementing the minimum nuclear deterrence no longer exists (Russia's nuclear deterrence's ability to stop the war is gone). Therefore, China's nuclear strategy must be adjusted.
For China, it is actually different from Western thinking. China is a civilization that has existed for 5,000 years, and its historical memory has not been interrupted. China has experienced multiple rounds of the rise and fall of dynasties. In China's eyes, the real war of national extinction (a war related to the survival of the country) is not a competition to slaughter opponents, but a competition for the country's recovery ability. For some countries, they seem very powerful, and after suffering a real blow, the country is completely destroyed. But for real strong countries, no one can really destroy them because they can be reborn from the ashes. (Recently, I accidentally heard a live broadcast by a retired officer, mentioning a little bit about China's layout after facing a nuclear strike.)
To put it simply, let's make a metaphor. How does a good fighter train? It's not just about learning how to attack with fists and feet, but first learning how to withstand attacks and injuries, and minimizing the damage to the minimum in the first place, so that you have the ability to punch your opponent again.
China's minimum nuclear deterrence strategy, especially the commitment not to use nuclear weapons first, is essentially telling the opponent that if you have the ability to kill me with the first punch, if you can't kill me with the first punch, you will regret it for the rest of your life and pay a price you can't imagine.
China's nuclear strategy construction is the strategic ability to kill the opponent under the premise of withstanding the opponent's first strike. Just a few decades ago, China's strength was not enough, and it could only use leverage to achieve nuclear deterrence balance. Today, China's strength is actually trying to tell all countries that after a global nuclear war, only China can recover the fastest and restore its war capabilities (only after listening to the content of that retired officer, you will understand how early China has started various layouts and plans).
What China pursues is that after the third world war, it is not a war between stones and sticks, but the opponent only has stones and sticks. To say one more sentence, China's preparation is to ensure that the surviving society after the war will not be chaotic, can still be mobilized, and will quickly restore its war capabilities (industrial capabilities). The opponent can't do it, and it will definitely fall into infinite chaos.
We are not interested in the so-called results of the Taiwan Strait military push by the United States, and we just find it infinitely interesting. Because the results of this kind of military push are basically to repel China in a limited war through a specific plan (the war only lasts for one round, that is, one attack), and it is considered that the war has been won and can be ended and negotiated. Chinese people laugh when they see this. Just look at the Russia-Ukraine war, how can this possibility appear. The United States has been established for 250 years, and there have been wars for only 16 years. China, on the other hand, has been continuously at war in its 5,000-year history. If China doesn't understand war and can't fight, it would have been destroyed and divided long ago.
