Answer:

The Treaty on the Prohibition of Nuclear Weapons (TPNW), adopted in 2017, represents a landmark agreement aimed at achieving global nuclear disarmament. Unlike previous treaties like the Non-Proliferation Treaty (NPT), which only restricted the spread of nuclear weapons, the TPNW outright bans their development, testing, stockpiling, and use. Its goal is to eliminate nuclear arsenals and promote peace, though challenges remain in securing widespread adherence, particularly from nuclear-armed nations.

Significance of the Treaty on the Prohibition of Nuclear Weapons (TPNW) in Promoting Nuclear Disarmament:

• Comprehensive Ban on Nuclear Weapons: TPNW aims for the complete abolition of nuclear weapons by prohibiting their development, testing, and possession.
  For example: As of 2024, over 70 nations have ratified the treaty, signalling a global consensus for disarmament.
• Global Recognition of Humanitarian Consequences: The treaty is driven by concerns over the catastrophic humanitarian impact of nuclear weapons.
  For example: The treaty highlights the long-term effects of nuclear fallout, drawing on events like the Hiroshima and Nagasaki bombings.
• Stigmatisation of Nuclear Arms: TPNW seeks to create a moral and legal stigma around nuclear weapons, similar to chemical and biological weapons.
  For instance: Nations that use or threaten to use nuclear weapons, like Russia during the Ukraine conflict, face global condemnation under the treaty’s ethos.
• Encouragement for Non-Nuclear States: TPNW strengthens the voice of non-nuclear-armed countries, pushing the nuclear states to rethink their arsenals.
  For example: Nations like New Zealand and Costa Rica, with no nuclear ambitions, are leading advocates of the treaty, emphasising collective security over nuclear deterrence.
• Legal Framework for Disarmament: The treaty offers a legal pathway for nuclear-armed states to disarm, providing mechanisms for verification and destruction.
  For instance: If nuclear states like France or China were to join, they would have to dismantle their arsenals under international supervision.
• Potential to Influence Global Norms: Even without major nuclear states’ participation, the treaty could shift global norms and diplomacy regarding nuclear weapons.
  For instance: The treaty has been endorsed by former NATO officials, reflecting a growing trend towards disarmament among military powers.
• Building Momentum for Other Treaties: The success of the TPNW can catalyse further arms control agreements, leading to broader disarmament efforts.
  For example: The Comprehensive Nuclear-Test-Ban Treaty (CTBT) could gain renewed attention as the TPNW strengthens the anti-nuclear narrative.

Effectiveness of TPNW in Balancing Nuclear Deterrence and Aspiration for a Nuclear-Free World:

• Challenges from Non-Participation of Nuclear Powers: Major nuclear states like the U.S., Russia, and India have not signed the TPNW, limiting its immediate impact.
  For example: These nations argue that nuclear deterrence is essential for maintaining strategic balance in global politics.
• Lack of Enforcement Mechanisms: The treaty lacks specific penalties for violations, making enforcement challenging without the participation of nuclear states.
  For example: Countries can sign and violate the treaty without facing significant consequences, as seen with the NPT violations by North Korea.
• Deterrence Doctrine vs. Disarmament: The belief in nuclear deterrence as a safeguard against major conflicts complicates disarmament efforts.
  For example: India’s nuclear doctrine, which emphasises credible minimum deterrence, makes immediate disarmament unlikely.
• Symbolic Progress Over Practical Impact: While the treaty has symbolic value in promoting disarmament, its practical effect is limited due to non-participation by major powers.
  For example: France and China maintain and even expand their nuclear arsenals, signalling a commitment to deterrence over disarmament.
• Diplomatic Pressure on Non-Signatory States: The TPNW places diplomatic pressure on nuclear-armed states and their allies to justify their continued reliance on nuclear deterrence.
  For example: NATO states face growing internal dissent over nuclear policies, with several former leaders advocating for disarmament.
• Potential for Future Integration: While current nuclear powers resist joining, the TPNW may lay the groundwork for future integration into global security frameworks.
• Incremental Steps Toward a Nuclear-Free World: The treaty represents an incremental step in the long-term goal of achieving global nuclear disarmament.
  For example: ICAN’s Nobel Prize win in 2017 highlighted global civil society’s role in promoting disarmament, further pushing the agenda forward.

The Treaty on the Prohibition of Nuclear Weapons (TPNW) represents a significant step toward global disarmament, despite its current limitations. While nuclear-armed states remain outside its framework, the treaty’s growing legitimacy could lead to long-term changes in global norms. Achieving a balance between nuclear deterrence and disarmament will require sustained diplomatic efforts and a gradual shift in international security priorities.
