Answer: (A) It is a bilateral strategic nuclear arms reduction treaty between the USA and the Russian Federation

The answer is (a) — New START (Strategic Arms Reduction Treaty) is a BILATERAL nuclear arms reduction treaty between the USA and Russia, signed in 2010 in Prague by Presidents Obama and Medvedev.

Key provisions:

  • Limits each country to 1,550 deployed nuclear warheads (down from previous limits).
  • Limits to 700 deployed delivery systems (ICBMs, submarine-launched missiles, heavy bombers).
  • Includes verification and inspection mechanisms.
  • Duration: Originally 10 years (2011-2021), extended to February 2026.
  • It replaced the earlier START I treaty (1991) and is the latest in a series of US-Russia arms control agreements.

Why not other options?

(b) No multilateral energy treaty exists among East Asia Summit members with this name.

(c) No Russia-EU energy treaty called 'New START.'

(d) BRICS has no treaty with this name — BRICS focuses on development cooperation, not nuclear arms.

Important context: New START is currently the LAST remaining major nuclear arms control treaty between the US and Russia, as other agreements (INF Treaty, Open Skies) have been terminated.

Why this was asked

New START is the only major nuclear arms control treaty still active between the US and Russia after other agreements like the INF Treaty were terminated.

The treaty was signed in 2010 by Obama and Medvedev, limiting each country to 1,550 deployed nuclear warheads and 700 delivery systems.

UPSC is testing if students can distinguish bilateral US-Russia nuclear agreements from multilateral economic cooperation treaties among other groupings.

New START Treaty: US-Russia Nuclear Arms Control

Must know

New START is a bilateral nuclear arms reduction treaty between USA and Russia, signed in 2010

Limits each country to 1,550 deployed nuclear warheads and 700 delivery systems

Extended until February 2026 - currently the last remaining major US-Russia arms control treaty

Good to know

Signed in Prague by Presidents Obama and Medmedev

The New Strategic Arms Reduction Treaty (New START) is the cornerstone of modern nuclear arms control between the world's two largest nuclear powers. It replaced the earlier START I treaty and represents the latest effort to manage nuclear arsenals through verified limits.

Deployed Nuclear Warheads

Various under different treaties

Treaty Mechanisms

Verification regime: On-site inspections and data exchanges to ensure compliance

Delivery systems: Covers ICBMs, submarine-launched ballistic missiles, and heavy bombers

Bilateral nature: Only between US and Russia, unlike multilateral non-proliferation treaties

Extension provision: Originally 10 years (2011-2021), extended by 5 years to 2026

Current Strategic Importance

New START gained critical importance after the collapse of other US-Russia arms control agreements:

• INF Treaty (Intermediate-Range Nuclear Forces) - terminated in 2019
• Open Skies Treaty - US withdrew in 2020, Russia in 2021
• This makes New START the sole remaining major nuclear arms control framework between the superpowers

Exam traps

Trap: Confusing New START with multilateral treaties - it's strictly bilateral (US-Russia only)

Trap: Mixing up with energy cooperation treaties - New START deals only with nuclear weapons

Trap: Associating with BRICS or East Asia Summit - these organizations have no nuclear arms treaties

Trap: Thinking it's about trade promotion - focus is purely arms reduction

World Affairs (International Relations)

US-Russia Arms Control: From Cold War to Present

Must know

START I (1991) was the first major post-Cold War nuclear reduction treaty

INF Treaty (1987-2019) eliminated intermediate-range missiles, now terminated

New START (2010-2026) is currently the only surviving major arms control treaty

INF Treaty

Open Skies

New START

Current warhead/delivery limits

Why Treaties Collapsed

INF Treaty breakdown: US accused Russia of developing 9M729 missile that violated range limits

Open Skies withdrawal: US cited Russian restrictions on flights over sensitive areas

Growing tensions: Ukraine conflict, cyber warfare, and military modernization programs

New technologies: Hypersonic weapons and cyber capabilities not covered by old treaties

Current Strategic Landscape

The collapse of multiple treaties leaves New START as the sole pillar of US-Russia nuclear stability. Both countries are modernizing their arsenals while the treaty framework shrinks, raising concerns about a new arms race without adequate controls.

Bilateral vs Multilateral Treaties

World Affairs (International Relations) bilateral multilateral

Treaty Types: Bilateral vs Multilateral Frameworks

Must know

Bilateral treaties involve exactly two parties (countries or entities)

Multilateral treaties involve three or more parties

Good to know

Arms control often uses bilateral approach for specific threats between major powers

Example (Arms Control)

New START (US-Russia)

NPT (191 countries)

Example (Trade)

India-UAE CEPA

WTO Agreements

When Each Type is Used

Bilateral for targeted issues: Border disputes, specific trade deals, direct military threats

Multilateral for global challenges: Climate change, nuclear non-proliferation, ocean governance

Arms control preference: Major powers often prefer bilateral for sensitive strategic weapons

Regional cooperation: Often starts bilateral, then expands multilateral (ASEAN model)

Exam traps

Trap: New START appears multilateral due to global impact, but it's strictly bilateral

Trap: Confusing NPT (multilateral non-proliferation) with START (bilateral reduction)

Trap: Energy cooperation treaties are typically multilateral - unlike nuclear arms control
