Understanding China’s Perceptions and Strategy Towards Nuclear Weapons

My paper on the India-China Border is in the Appendix at pages 16-31. Other case studies are the Korean War (1950-53), Taiwan crises (1954-55 and 1958), Cuban missile crisis(US-Soviet Union in 1962) and Sino-Soviet border conflict(1969). Since China went nuclear only in 1964, the first three only indicate evolving Chinese thinking on nuclear weapons.

The India-China experience does not square with other case studies and its conclusions because the character of threat perception is different and both India and China have declared a more restrained no-first-use policy.

The Global Nuclear Order is Under Strain

Published in the Hindu on January 3, 2024

To gain legitimacy, any global order needs to fulfil two conditions. First, a convergence among the major powers of the day; and, second, successfully presenting the outcome as a global public good to the rest of the world. The global nuclear order (GNO) was no exception but, today, it is under strain.

Lessons of the Cold War

The GNO was created in the shadow of the Cold War, with the U.S. and the U.S.S.R., leading the Western and the Socialist blocs, respectively. Following the 1962 Cuban Missile Crisis, when the two came perilously close to launching a nuclear war, both President John F. Kennedy and General Secretary Nikita Khrushchev understood two political realities. First, as the two nuclear super-powers, they needed bilateral mechanisms to prevent tensions from escalating to the nuclear level. And, second, nuclear weapons were dangerous and, therefore, their spread should be curbed. This convergence created the GNO.

During the Cuban crisis, a secret back-channel between President Kennedy’s brother Robert Kennedy and Soviet Ambassador Anatoly Dobrynin, helped resolve the crisis. The first bilateral measure was the Hot Line, established in 1963, to enable the leaders to communicate directly. The Hot Line (later upgraded into Nuclear Risk Reduction Centres) was followed by arms control negotiations as the two nuclear superpowers sought to manage their nuclear arms race and maintain strategic stability.

To control proliferation, the U.S. and the U.S.S.R. initiated multilateral negotiations in Geneva in 1965 on a treaty to curb the spread of nuclear weapons. Three years later, the Nuclear Non-Proliferation Treaty (NPT), opened for signature. It began modestly with less than sixty parties but today, it is widely described as the cornerstone of the global nuclear order with 191 adherents.

The third element of the global nuclear order came into existence in 1975. India had chosen not to sign the NPT, and in 1974, stunned the world by conducting an underground nuclear explosion, or PNE. Seven countries (the U.S., U.S.S.R., U.K., Canada, France, Japan, and West Germany) held a series of meetings in London and concluded that ad-hoc export controls were urgently needed to ensure that nuclear technology, transferred for peaceful purposes, not be used for PNEs. London Club (as it was originally known) sounded inappropriate and later transformed into the Nuclear Suppliers Group, consisting of 48 countries today, which observe common guidelines for exporting nuclear and related dual-use materials, equipment, and technologies. Though Soviet Union and India enjoyed close relations, having signed the Indo-Soviet Friendship Treaty in 1971, U.S.S.R. was committed to upholding the GNO, and a founding member of the London Club.  

Sustaining the nuclear order

The GNO has held reasonably well, particularly on two fronts. First, the taboo against nuclear weapons has held since 1945. It is a matter of debate how far the U.S.-U.S.S.R. arms control process helped preserve the taboo or whether it was just plain luck but the fact is that humanity has survived 75 years of the nuclear age without blowing itself up.

Second, non-proliferation has been a success. Despite dire predictions of more than twenty countries possessing nuclear weapons by the 1970s, (there were five in 1968 – the U.S., U.S.S.R., U.K., France, and China) only four countries have since gone nuclear, i.e., India, Israel, North Korea, and Pakistan. Even after the Cold War ended, non-proliferation remained a shared objective and Moscow and Washington cooperated to ensure that Belarus, Ukraine, and Kazakhstan that hosted Soviet nuclear weapons and possessed some capabilities, were denuclearised. In 1995, the NPT, originally concluded for 25 years, was extended into perpetuity.

On other counts, the record is mixed. Arms control did not end the U.S.-U.S.S.R. nuclear race; in fact, their arsenals grew from 28,000 bombs in 1962 to over 65,000 bombs in the early 1980s but the dialogue and some agreements provided a semblance of managing the arms race. Agreements like SALT I and II, ABM treaty, INF Treaty, START I and the New START were concluded. Since the late 1980s, the U.S. and Soviet arsenals have declined sharply, to below 12,000 bombs today, though much of this can be attributed to the end of the Cold War rivalry and the breakup of the U.S.S.R.

The two nuclear hegemons shared a notion of ‘strategic stability’ based on assured second strike capability, guaranteed by the enormous arsenals that both had built up. This eliminated any incentive to strike first ensuring deterrence stability. Arms control negotiations led to parity in strategic capacities creating a sense of arms race stability, and fail-safe communication links provided crisis management stability. These understandings of nuclear deterrence in a bipolar world outlasted the Cold War but are under question.

Changing geopolitics

Today’s nuclear world is no longer a bipolar world. The U.S. faces a more assertive China, determined to regain influence, regionally and globally. This rivalry is different from the Cold War because both economies are closely intertwined and further, China is an economic and technological peer rival. China has resented the U.S.’s naval presence in the South China and East China Seas and since the last Taiwan Strait crisis in 1996, has steadily built up its naval and missile capabilities. These were on display in August last year to demonstrate changing power equations following Speaker Nancy Pelosi’s visit to Taiwan. 

Changing geopolitics has taken its toll on the treaties between the U.S. and Russia. In 2002, the U.S. withdrew from the Anti-Ballistic Missile (ABM) Treaty and in 2019, from the Intermediate-Range Nuclear Forces (INF) Treaty on grounds that Russia was violating it. The only remaining agreement, New START, will lapse in 2026; its verification meetings were suspended during the COVID-19 outbreak and never resumed. Strategic stability talks began in 2021 following the Geneva meeting between Presidents Joe Biden and Vladimir Putin, but collapsed with the Ukraine war. Last month, Russia de-ratified the Comprehensive Test Ban Treaty (CTBT) to bring it on a par with the U.S., raising concerns about the resumption of nuclear testing. As U.S. relations with Russia went into a nosedive, the U.S. is facing a new situation of two nuclear peer rivals who are exploring new roles for more usable weapons. Moreover, Russian nuclear sabre rattling to warn North Atlantic Treaty Organisation and the U.S. against escalation in Ukraine has revived nuclear concerns. The old definitions of strategic stability no longer hold.

The Cold War convergence on non-proliferation has run its course; also, nuclear weapons technology is a 75-year-old technology. The U.S. has always had a pragmatic streak shaping its policy approaches. It turned a blind eye when Israel went nuclear in the 1960s-70s and again, when China helped Pakistan with its nuclear programme in the 1980s. More recently, the nuclear submarine AUKUS deal (Australia, U.K., U.S.) with Australia, a non-nuclear weapon state, is raising concerns in the NPT community.

During the 1970s, South Korea began to actively consider a nuclear weapons programme, spurred by the U.S. withdrawal from Vietnam. However, France withdrew its offer to supply a reprocessing plant to South Korea under U.S. pressure in 1975-76 and South Korea was persuaded to join the NPT. Recent opinion polls indicate a 70% support for developing a national nuclear deterrent and 40% for reintroducing U.S. nuclear weapons (withdrawn in 1991) on its territory.

From 1977 to 1988, the U.S. actively subverted Taiwan’s nuclear weapons programme as it stepped up a normalisation of ties with China. As a nuclear victim, the Japanese public retains a strong anti-nuclear sentiment but there is a shift, visible in Japan’s decision to double its defence spending over next five years.

During the Cold War, the U.S.’s nuclear umbrella tied its European allies closer. Today, domestic compulsions are turning the U.S. inwards, raising questions in the minds of its allies about its ‘extended deterrence’ guarantees, especially in East Asia. Japan, South Korea, and Taiwan have the technical capabilities to develop their independent nuclear deterrents within a short time, given political will. It is only a matter of time before U.S. pragmatism reaches the inevitable conclusion that more independent nuclear deterrent capabilities may be the best way to handle the rivalry with China.  

The GNO is looking increasingly shaky.

Nuclear Signaling, the Need for New Guard Rails

Published in the Hindu on August 4, 2023

The conflict in Ukraine and the recourse to nuclear rhetoric have revived concerns about nuclear escalation management between the major nuclear powers. Since the end of the Cold War, the United States-Russia nuclear rivalry had taken a backseat. Instead, North Korea, Iran and India-Pakistan got attention with many analysts getting nostalgic about ‘nuclear stability’ during the Cold War. But as is becoming clear now, in today’s changed political environment, the escalation management lessons of the Cold War no longer seem to work for the U.S. and Russia.

Deterrence failure

In June 2021, U.S. and Russian Presidents, Joe Biden and Vladimir Putin met in Geneva. Nuclear arms control was a high priority item on the agenda but no progress proved possible. As concerns grew about Russian troop presence in Belarus on the Ukrainian border, Central Intelligence Agency Director Bill Burns flew to Moscow in November to spell out the consequences of aggression. In January 2022, Secretary of State Anthony J. Blinken met Foreign Minister Sergei Lavrov in Geneva to reiterate the message. On February 24, Russia began its “special military operation” in Ukraine. U.S. attempts to deter Russian aggression had failed.

Even as North Atlantic Treaty Organisation (NATO) leaders met to decide their response, Mr. Biden made it clear that the U.S. was determined to avoid a Third World War or allowing the conflict to escalate into a NATO-Russia conflict. After freezing of Russian reserves and a slew of financial, energy-related and political sanctions, other elements of military assistance, lethal and non-lethal began to take shape. Intelligence sharing and restoring Internet connectivity was the first step. The second was the supply of ammunition and some weapon systems with which the Ukrainian forces were familiar. NATO deepened its military involvement by providing gradually more and more sophisticated weapon systems, beginning with Javelin and Stinger missiles, and moving on to Patriot missile defence batteries, long range Himars, Storm Shadow and Scalp long range missiles and now F-16s. Russian attempts to deter NATO involvement had failed.

On February 7, 2022, Mr. Putin warned that “if Ukraine attempts to take back Crimea, European countries will be in conflict with Russia, which is a leading nuclear power superior to many NATO countries in terms of nuclear force.” Annual nuclear exercises, normally scheduled for autumn were announced for February 17, with Mr. Putin personally witnessing them. Announcing the launch of “special military operations”, his words of caution were, “whoever tries to hinder Russia will face consequences never seen in history.” To drive home the threat, on February 27, Russian nuclear forces were placed on a “special combat readiness” with leave for all personnel cancelled.

Even as the U.S. issued blunt warnings to Russia against using tactical nuclear weapons, in the first week of March, NATO decided against a no-fly-zone and Poland, Slovakia and Bulgaria announced that they would not be sending MiG aircraft to Ukraine on account of Russian threats against their airfields from where these aircraft were to take off.

Russian officials tried to downplay the nuclear threat by pointing out that Russia would resort to nuclear use only if faced with an existential threat while U.S. officials tried to convey reassurance to their European allies that while Mr. Putin’s threats be taken seriously, there were no indications of unusual activity at nuclear sites.

President Biden declared on April 24, “We are neither encouraging nor enabling Ukraine to strike beyond its borders’, and adding that the “U.S. was not seeking regime change in Russia.” In short, the U.S. objectives were to support Ukraine, bolster NATO unity and avoid any direct conflict with Russia. Ukraine is not a NATO member and so does not have the security of the nuclear umbrella provided by U.S. policy of ‘extended deterrence.’

Russia’s resort to nuclear rhetoric failed to deter NATO involvement though it influenced its pace and timing. Therefore, both Russia and the U.S. are operating in a grey zone, taking turns at escalatory rhetoric even as they probe each other’s red lines. During the Cold War, the U.S. and the former Soviet Union engaged in multiple proxy wars, Vietnam in the 1960s and Afghanistan in the 1980s, but these were in distant theatres.

Cold War lessons

Deterrence is fundamentally based on the assumption that both adversaries are rational enough to judge when costs outweigh the benefits of the act. Nuclear deterrence adds a conundrum. With their huge arsenals that provided for assured second strike capability, neither the U.S. nor the Soviet Union had an incentive to try a surprise first strike. This realization was crucial in shaping nuclear deterrence theory.

Thomas Schelling, whose writings during the 1960s and 1970s shaped nuclear deterrence thinking (he won the Economics Nobel in 2005) concluded that nuclear weapons were not usable but had political utility in terms of preventing a war with another nuclear power. Clearly, Schelling was looking at the situation between the U.S. and the Soviet Union which had no territorial dispute.

Schelling also concluded that even though any use was “irrational,” the nuclear threat had to be “credible” in order to deter. This introduced a degree of uncertainty into the equation. Using his economics training, Schelling interpreted the uncertainty as risk that could be analysed in terms of probabilities. Risk was intended to induce rationality in the adversaries. Realizing the conundrum, Schelling concluded that the key to making nuclear deterrence credible is through escalation and raising the risk, that in the final analysis, “leaves something to chance.”

This, along with the lessons of the 1962 Cuban missile crisis kept the U.S. and Soviet rhetoric in check during the Cold War even as they engaged in proxy wars outside Europe, and away from NATO and Warsaw pact territories. Today, there is no Warsaw Pact and NATO has expanded to include a number of former Warsaw Pact members. The Ukraine conflict has persuaded Sweden and Finland to give up their long-standing neutrality and seek security under NATO’s nuclear umbrella.

Probing for red lines

Russia’s nuclear doctrine issued on June 2, 2020 specifies two conditions under which Russia would use nuclear weapons – “…in response to the use of nuclear weapons and other types of weapons of mass destruction against it/or its allies” and “in the case of aggression against the Russian Federation with the use of conventional weapons, when the very existence of the state is put under threat.” Mr. Putin has declared more than once that Ukrainians and Russians are one people with a shared history; Russia therefore doesn’t see Ukraine as entirely ‘sovereign’.

Second, there is the oft-cited escalate-to-deescalate approach that implies using tactical nuclear weapons to overcome a stalemate on the battlefield, thus forcing a termination of hostilities on favourable terms. In its 2022 National Security Strategy, the U.S. rejected this by declaring that first use would not lead to de-escalation on Russian terms “but alter the nature of conflict creating potential for uncontrolled escalation.”

U.S. caution is reflected in calibrating supply of more sophisticated weapons by continuously probing Russian red lines even though Ukrainian demands continue to grow. Meanwhile, it suits Russia to increase ambiguity. It is also likely that since Russia failed to achieve its military objectives, its thresholds are evolving.

Daniel Kahneman and Amos Tversky’s path breaking studies in economics showed that humans often tend to double down on bad bets because of ‘loss aversion.’ The Cold War escalation management lessons applied to a different world; today, the U.S. and Russia no longer enjoy parity and Russia’s red lines are fuzzy.

Nuclear signaling today is taking place in uncharted political territory. New guard rails are necessary if the nuclear taboo has to be preserved.

It’s Time to Tweak the Nuclear Policy

Published in Hindustan Times on May 15, 2023

India’s nuclear tests on May 11 and 13, 1998, stunned the world. This was not the first; in 1974, India had tested but called it a peaceful nuclear explosion (PNE). This time, Prime Minister Atal Behari Vajpayee declared that India was now a nuclear-weapon-state. Addressing parliament on the subject on May 27, he also placed a paper – “Evolution of India’s Nuclear Policy” – that provided the rationale for the tests and spelt out the elements of India’s doctrine that defined India as a reluctant but responsible nuclear power.

When India refused to sign the Nuclear Non-Proliferation Treaty (NPT) in 1968, its “nuclear option” was born. In subsequent decades, preserving the option became the primary political and diplomatic objective. Through more than three decades of domestic political changes, policy continuity was sustained.

Meanwhile, Pakistan pushed ahead with its programme and by early 1980s, it was enriching uranium at Kahuta and by late 1980s, had weaponised its deterrent with Chinese help. As the frontline state in the United States’ covert war against the Soviet Union in Afghanistan, Pakistan managed to make the U.S. turn a blind eye to its nuclear developments.

There was a growing realisation that given technological advances since the 1974 PNE, the “nuclear option” could no longer remain viable and needed to be exercised. Post Cold War global developments with tightening dual-use export controls were also squeezing the Indian option. In 1995, the NPT was extended into perpetuity, freezing a nuclear order that India had long considered arbitrary and discriminatory. Negotiations on a Comprehensive Test Ban Treaty (CTBT) began in 1994 with the Clinton administration pushing to complete it in 1996.

In 1995, France and China were still undertaking tests to validate designs and acquire data that would help sustain their capabilities with ‘zero-yield’ tests in their laboratories. Prime Minister Narsimha Rao gave the green light for tests and preparatory work began at Pokhran. In early December, days before the tests were scheduled, U.S. satellites picked up imagery of activity at Pokhran. The tests were postponed till after the general elections and meanwhile, Indian stand on the CTBT negotiations hardened.

Prime Minister Vajpayee toyed with the idea of the tests in 1996 but decided against it as his tenure was a mere 13 days. The next opportunity arose when he became PM again in 1998, and the die was cast.

The 1998 declaration of India as a nuclear-weapon-state marked a decisive break. It generated its own challenges, both domestic and external. A new kind of policy continuity was crafted. Domestically, it related to the nuclear doctrine and the configuration of the nuclear arsenal into the defence and decision-making structures. Externally, it was to gain acceptance as a responsible nuclear power and second, to stabilise deterrence relations with India’s adversaries.

After 25 years, the domestic challenge is still a work in progress. To maintain a credible minimum deterrent, a nuclear triad was considered necessary. The land-based missile force has now inducted Agni IV with an estimated range of 3500 kms. Agni V and Agni VI are expected to extend the ranges to beyond 6000 kms. The nuclear submarine programme has made slow progress with Arihant having undertaken its firs patrol last year. However, it currently carries K-15 (Sagarika) missile that has a limited range of 700 kms. Longer range missiles are under development.

Though India has no intention of embarking on a nuclear arms race with any other country, it must factor in technological developments that can have an impact on the credibility of its deterrent. Increasing use of dual use systems like hypersonics and cruise missiles, conventional precision global strike weapons blur the dividing line between nuclear and conventional systems. Digitisation renders both early warning systems and command and control systems vulnerable to counter-space and offensive cyber action.

These developments have led to questions as to how to define the ‘minimum’ and whether the no-first-use policy needs review. Some critics point to Kargil in 1999 and the Mumbai attacks in 2008 as evidence of failure of nuclear deterrence and would advocate a more robust posture. However, such criticism is ill founded. Indian doctrine is intended to deter threat and use of nuclear weapons. Dealing with Kargil-type attacks or terrorist strikes requires building conventional and intelligence capabilities that can offer a range of response options.

The external diplomatic challenge of gaining acceptance as a responsible nuclear power has been achieved in great measure. The Vajpayee government was proactive in reaching out to key countries, particularly the U.S. since it had taken the lead in condemning the tests and calling for sanctions.

The dialogue between Deputy Secretary of State Strobe Talbott and Foreign Minister Jaswant Singh between 1998 and 2000 remains the most intense phase of bilateral engagement with 18 rounds of talks in 24 months. It remained inconclusive in not meeting either side’s stated objectives; yet, it was immensely productive in clearing the path towards the Next Steps in Strategic Partnership and eventually the India-U.S. Civil Nuclear Cooperation Agreement following the exceptional waiver by the Nuclear Suppliers Group (NSG) in 2008 – another milestone that completes 15 years in 2023. The NSG waiver legitimised India’s civilian nuclear trade and has enabled over a dozen cooperation agreements to be concluded.

This has been possible because the post-1998 policy too has been marked by a similar continuity that characterised it in its early years. Today, changing geopolitics has revived rivalries among major nuclear powers even as the geopolitical centre of gravity has shifted from Euro-Atlantic to the Indo-Pacific. Navigating these challenges may need policy adjustments that will be strengthened by consensus and continuity.
