The fragile state of nuclear disarmament

The fragile state of nuclear disarmament


  • The Stockholm International Peace Research Institute (SIPRI) released its yearbook a few days back highlighting some worrying trends of the past year in international security.

  • The expected rise of the global nuclear arsenal was the chief cause of concern among SIPRI experts.

What have been the trends in military spending?

  • During 2012-2021, military spending as a percentage of gross domestic product has largely been stable.

  • Russia leads the charge in absolute numbers of nuclear inventory (5977 against the U.S.’s 5428), however it is the U.S. that has the largest number of deployed warheads (1744 against Russia’s 1588).
  • The U.K. has 225 nuclear weapons in its inventory, while France has 290, China has 350, India has 160, Pakistan has 165. Israel is estimated to have 90 and North Korea 20.

What about global arms imports?

  • All nuclear weapon owning states have, over the years, stated and worked upon their intention to modernise multiple facets of their armed forces—ranging from the development of newer and more efficient nuclear submarines, aircraft carriers, fighter jets, manned and unmanned aerial vehicles to the growing spread of the use of missile defence systems which may result in aggravating security concerns for other countries.
  • The yearbook has highlighted India as being the top weapons importer during the 2017-2021 period. Other countries to feature in the top five arms importers list include Saudi Arabia, Egypt, China, and Australia.
    • According to SIPRI, these five nation states account for 38% of total global arms import.

What are the key developments/concerns flagged by the yearbook?

  • Low level border clashes between India and Pakistan,
  • The civil war in Afghanistan, and
  • The armed conflict in Myanmar as some of the worrying indicators of an unstable system.
  • It also highlighted three cause of concern trends:
    • Chinese-American rivalry,
    • Involvement of state and non-state actors in multiple conflicts, and
    • Climatic and weather hazards pose.
  • The marginal downsizing observed in the nuclear arsenal has come mostly from the U.S. and Russia dismantling retired warheads.
  • China’s recent activities surrounding construction of 300 new nuclear missile silos have also been turning heads.
  • Over in the subcontinent, India and Pakistan seem to be making gains over their nuclear arsenal (in absolute numbers) while also looking at the development and procurement of newer and more efficient forms of delivery systems.
  • There were some advances over the rollout of the 2015 Joint Comprehensive Plan of Action, Iran increased its enrichment of Uranium-235 to 60% in 2021. It also reported that Iran’s military budget grew to $24.6 billion, growing for the first time in four years.

What is the general attitude among countries about existing nuclear and arms related treaties?

  • The leaders of the P5 countries (China, France, Russia, the U.K. and the U.S.) issued a joint statement affirming the belief that “a nuclear war cannot be won and must never be fought”.
  • The joint statement also highlighted their seemingly collective belief that bilateral and multilateral arms control agreements and commitments were indeed important.
  • The dichotomy of this sentiment against the upward trend in absolute numbers of arms and nuclear arsenals is rather unsettling.
  • The recent Russian invasion of Ukraine and the subsequent NATO bids by Finland and Sweden seem to be telling events.
  • The year 2021 also saw the Treaty on the Prohibition of Nuclear Weapons, 2017 coming into effect. The Nuclear Suppliers Group (NSG) and the Missile Technology Control Regimes (MTCR) held their annual meetings despite decision making being limited due to the COVID-19 pandemic.

What lies ahead?

  • The recent geopolitical events transpiring around the world in practically all regions have made the global security climate more unstable. A sense of precariousness lulls the air.
  • It is further aided by actions of authoritarian leaders of not just non-democratic systems but also of strongmen leaders of democratic systems.
  • The muscular military policies of these nations coupled with the continuous use of rhetoric that fuel public sentiment over the state’s use of military assets make ripe conditions for the situation to further deteriorate.


  • A strong political opposition would be needed to help keep the ruling dispensation in check.
  • Furthermore, the two largest nuclear weapons holding states need to take on a more engaging role in the international arena. SIPRI’s yearbook, while not being devoid of some challenges, forces us to look critically at how the global disarmament project seems to be going.
