2. What are the key provisions of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT)?
The NPT has three main pillars:
- •Non-proliferation: Non-nuclear weapon states agree not to acquire nuclear weapons.
- •Disarmament: Nuclear weapon states commit to pursue disarmament negotiations.
- •Peaceful use of nuclear technology: Non-nuclear weapon states have the right to develop nuclear energy for peaceful purposes under IAEA supervision.
Exam Tip
Focus on the three pillars of the NPT for both prelims and mains.
3. How does the IAEA contribute to preventing nuclear proliferation?
The International Atomic Energy Agency (IAEA) plays a crucial role by verifying that non-nuclear weapon states are not diverting nuclear materials from peaceful uses to weapons programs. This is achieved through inspections and monitoring activities.
Exam Tip
Remember that IAEA's inspections are a key tool in verifying compliance with the NPT.
4. What is the Joint Comprehensive Plan of Action (JCPOA), and what is its significance in the context of nuclear proliferation?
The Joint Comprehensive Plan of Action (JCPOA), also known as the Iran nuclear deal, was an agreement reached in 2015 between Iran and the P5+1 countries. It aimed to limit Iran's nuclear program in exchange for the lifting of economic sanctions. Its significance lies in its attempt to prevent Iran from developing nuclear weapons.
Exam Tip
Note the year of JCPOA agreement and the parties involved for prelims.
5. How does the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) work in practice?
In practice, the NPT relies on a combination of commitments from member states, verification by the IAEA, and diplomatic efforts to prevent nuclear proliferation. Non-nuclear weapon states commit not to acquire nuclear weapons, while nuclear weapon states commit to disarmament negotiations. The IAEA monitors nuclear activities to ensure compliance.
6. What are the limitations of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT)?
The NPT has several limitations:
- •It does not include all countries: Some countries, like India, Pakistan, and Israel, have never signed the treaty.
