Revision summary
Nuclear proliferation is the spread of weapons, fissile material, and know-how to States or terrorists. The NPT is the legal core but divides 1967 nuclear-weapon States from others; India is not a party. IAEA safeguards watch civilian facilities; they do not by themselves cap a military programme. NSG export rules and India’s 2008 waiver govern sensitive nuclear trade. UNSCR 1540 and national WMD laws target non-State actors; CTBT and FMCT remain unfinished.
Model answer
Introduction
Nuclear proliferation is the spread of nuclear weapons, fissile material, and the know-how to make them, to more States or to non-State actors. The control system is a patchwork of treaties, supplier cartels, and UN resolutions built after 1945 and especially after 1968. It slows the spread. It has not abolished the bomb, and it still sits uneasily with States that never joined the NPT as weapons parties.
Body
Issues of proliferation
- Horizontal spread: more States seeking a bomb (historical cases and continuing dual-use nuclear energy programmes).
- Vertical spread: existing weapons States modernising arsenals, which undercuts the NPT bargain of disarmament for non-proliferation.
- Breakout and latency: civilian enrichment and reprocessing that can be turned to a weapon on a political decision.
- Non-State risk: theft of material, dirty bombs, and scientist leakage — the nightmare after 9/11 and A.Q. Khan-type networks.
- Regional triads: South Asia and the Korean peninsula show that neighbourhood rivalry, not only global ideology, drives demand.
- Hypocrisy politics: NPT divides nuclear-weapon States (1967 cut-off) from the rest; India, Israel, and Pakistan sit outside that bargain.
Existing control mechanisms
- NPT (1968/1970): cornerstone — non-nuclear parties forgo weapons; five recognised NWS promise not to transfer; peaceful use under safeguards. India is not a party.
- IAEA: safeguards, additional protocol, and inspections on declared civilian facilities; it cannot police an unsafeguarded military programme by itself.
- NSG: Nuclear Suppliers Group export guidelines on sensitive technology; India’s 2008 waiver is the civil-nuclear exception after the U.S. deal.
- CTBT and FMCT: test ban and fissile-material cut-off remain incomplete (CTBT not in force; FMCT still negotiated), so testing and stocks are a political, not fully legal, brake.
- MTCR, Wassenaar, Australia Group: related dual-use and missile/chemical-biological export clubs.
- UNSCR 1540 (2004): binds all States to keep WMD from non-State actors through domestic law and border control.
- National export controls: India’s WMD Act and SCOMET lists are the home half of the same mesh.
- Control is therefore layered: treaty, cartel, UN, and national law. Gaps remain where a State stays out, cheats, or a terrorist seeks a few kilograms.

Conclusion
Proliferation issues are more bombs, more States, latent civilian fuel cycles, and non-State theft. The control mesh is NPT, IAEA, NSG, incomplete CTBT/FMCT, UNSCR 1540, and national export law. India is outside the NPT as a weapons State but inside civil safeguards and NSG trade after 2008. The system manages risk; it does not uninvent the weapon.

-
Does the NPT ban all nuclear weapons?
It bans new weapons States among parties. Five States are recognised NWS, and three nuclear-armed States remain outside.
-
Is IAEA a world nuclear police?
It inspects agreed civilian sites. A secret military programme needs national intelligence and politics, not only IAEA seals.

What do you understand by "leaving no one behind" with reference to sustainable development goals?
Economic planning and NITI Aayog
Leaving no one behind is the 2030 Agenda pledge to reach the poorest and most excluded first. Averages hide caste, gender, disability, and geography; disaggregated data are required. NITI Aayog’s SDG India Index and Aspirational Districts name lagging units. DBT, Aadhaar, and Jan Dhan try to put transfers in the beneficiary’s account. PM-JAY, POSHAN, PMAY, Samagra Shiksha, and MGNREGA are the large service rails.

Economic planning and NITI Aayog
NITI Aayog (2015) replaced the Planning Commission as a think tank, not a Plan-fund body. Objectives: cooperative federalism, SDG monitoring, innovation, and programme design. The Three-Year Action Agenda ran 2017–18 to 2019–20 under a 15-year vision and 7-year strategy. Priorities included jobs, farm income, infrastructure, inclusion, and governance. It was indicative; Union and State budgets still spend, while NITI tracks ranks and districts.

"Indian food processing industry has not grown with the pace of developed countries." Discuss it.
Food processing
India grows a lot of food but processes a smaller share than developed countries. Thin cold chain, uneven farm lots, slow Mega Food Parks, and compliance costs explain the lag. PMKSY (SAMPADA) funds parks, cold chain, and agro-processing clusters. Operation Greens and food-processing PLI target price crashes and branded scale. FSSAI, FPOs, and e-NAM help quality only when supply contracts exist.
