<h4>Introduction to Nuclear Disarmament Efforts</h4><p><strong>Nuclear disarmament efforts</strong> refer to the international initiatives and treaties aimed at reducing, limiting, or completely eliminating nuclear weapons. These efforts are crucial for global peace and security, preventing the proliferation of these destructive devices.</p><div class='key-point-box'><p>The primary goal is to mitigate the existential threat posed by <strong>nuclear weapons</strong>, fostering a world free from their use or threat of use.</p></div><h4>Treaty on the Non-Proliferation of Nuclear Weapons (NPT)</h4><p>The <strong>Treaty on the Non-Proliferation of Nuclear Weapons (NPT)</strong> is a landmark international treaty. It entered into force in <strong>1970</strong>, becoming a cornerstone of the global non-proliferation regime.</p><div class='info-box'><ul><li><strong>Purpose:</strong> To prevent the spread of nuclear weapons and weapons technology.</li><li><strong>Goal:</strong> To promote cooperation in the peaceful uses of nuclear energy and further the goal of achieving nuclear disarmament.</li></ul></div><p>Despite its widespread acceptance, the <strong>NPT</strong> has faced significant criticism. It is often perceived as discriminatory, creating a clear division between <strong>nuclear-armed states (NWS)</strong> and <strong>non-nuclear-weapon states (NNWS)</strong>.</p><div class='key-point-box'><p>Critics argue that the treaty legitimizes the possession of nuclear weapons by five states while imposing strict obligations on others, leading to an unequal framework.</p></div><h4>Comprehensive Nuclear-Test-Ban Treaty (CTBT)</h4><p>The <strong>Comprehensive Nuclear-Test-Ban Treaty (CTBT)</strong> is another pivotal instrument in nuclear disarmament. Its primary objective is to ban all nuclear explosions, regardless of their environment.</p><div class='info-box'><ul><li><strong>Objective:</strong> To curb the development of new types of nuclear weapons.</li><li><strong>Scope:</strong> Prohibits nuclear weapons test explosions and any other nuclear explosion.</li></ul></div><p>Although widely supported, the <strong>CTBT</strong> has not yet fully entered into force. This is due to the non-ratification by several key states whose adherence is necessary for its full legal effect.</p><div class='exam-tip-box'><p>UPSC often asks about the status of international treaties like <strong>CTBT</strong> and the reasons for their non-entry into force, especially concerning <strong>India's stance</strong>.</p></div><h4>Treaty on the Prohibition of Nuclear Weapons (TPNW)</h4><p>The <strong>Treaty on the Prohibition of Nuclear Weapons (TPNW)</strong> represents a more recent and robust effort towards complete nuclear disarmament. It was adopted in <strong>2017</strong> and entered into force in <strong>2021</strong>.</p><div class='info-box'><p>The <strong>TPNW</strong> includes a comprehensive set of prohibitions on participating in any nuclear weapon activities. This makes it a significant step towards stigmatizing nuclear weapons.</p></div><p>Under the <strong>TPNW</strong>, states parties undertake not to develop, test, produce, acquire, possess, stockpile, use, or threaten to use <strong>nuclear weapons</strong>. It also prohibits assisting or encouraging any of these activities.</p><div class='key-point-box'><p>This treaty goes further than previous agreements by explicitly outlawing nuclear weapons, treating them similarly to chemical and biological weapons.</p></div>
