A START for multilateralism: Nuclear proliferation needs a global treaty

10 Feb 2026

Global Security Threats and Nuclear Armament

The perception of global security threats has intensified over the past five years, driven by the rise of irredentism and neo-imperialism among nuclear-armed nations such as the United States, Russia, China, Israel, and Pakistan.

Expiration of the New Strategic Arms Reduction Treaty (START)

  • The New START, signed in 2010 between the US and Russia, expired on February 4, leading to concerns about the lack of a new nuclear-arms control agreement.
  • The absence of such an agreement could result in increased deployment of nuclear warheads by the US and Russia.
  • The treaty's expiration raises questions about the effectiveness of bilateral treaties in deterring global nuclear proliferation.

Nuclear-Armed States and Stockpiles

  • The US and Russia together hold 90% of the world's nuclear weapons.
  • As of January 2025, there are nine nuclear-armed states with a total of 12,241 warheads.
  • 9,614 warheads are in military stockpiles ready for potential use.
  • China is noted for its rapidly growing nuclear arsenal, with 600 warheads and plans for 350 intercontinental ballistic missile silos.
  • India has surpassed Pakistan in the number of warheads, holding 180 compared to Pakistan's 170.

Increasing Nuclear Tensions

  • Nuclear arms races are escalating in regions like West Asia, East Europe, and East Asia due to rising security threat perceptions and nationalism.
  • Nuclear weapons, while not preventing conflict, pose the risk of escalation, particularly under nationalist leaders like Trump, Putin, and Xi Jinping.
  • A multilateral treaty involving all nuclear-armed nations is critical for global peace and security.

Role of International Treaties

  • The Non-Proliferation Treaty (NPT) obligates 191 states to negotiate nuclear disarmament, though neither India nor Pakistan has signed it.
  • The Treaty of Prohibition of Nuclear Weapons, adopted in 2017, prohibits activities related to nuclear weapons; however, none of the nine nuclear-armed states have signed it.
  • The expiry of New START presents an opportunity for renewed international efforts towards nuclear disarmament.

Nuclear Arms Race

A competition between nations for superiority in the development and accumulation of weapons of mass destruction, particularly nuclear weapons. It can lead to increased global instability and risk of nuclear conflict.

Intercontinental ballistic missile (ICBM) silos

Underground structures designed to house and protect ICBMs, allowing for their rapid launch. They are a key component of a nation's strategic nuclear deterrent.

Nuclear warheads

Nuclear warheads are the explosive payloads of nuclear weapons, designed to detonate and release immense destructive energy. In the context of arms control treaties like New START, they are a key metric for limiting the strategic nuclear capabilities of states.
