1. International Day of Yoga 2025
GS area: GS-II (International institutions, Government schemes), GS-III (Health)
The 11th International Day of Yoga was observed on 21 June 2025. PM Modi led the central event at Visakhapatnam under the theme "Yoga for One Earth, One Health."
- Origin: The United Nations General Assembly adopted Resolution 69/131 on 11 December 2014 to declare 21 June as International Day of Yoga. This was the first recognition by a UN body; 175 member states co-sponsored the resolution.
- Governing ministry: Ministry of AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homeopathy) coordinates all national-level programming.
- Participation growth: Global participation rose from 9 crore people in 2018 to 24.53 crore people in 2024. This trajectory is cited as evidence of mass health uptake.
- Yoga Sangam: A nationwide simultaneous event held at over 1 lakh locations across India. The 2025 edition ran Harit Yoga sessions that paired yoga practice with tree planting at each site.
- One Health alignment: The World Health Organization backs aligning Yoga Day's theme with the One Health framework. One Health treats human, animal and ecosystem health as inseparable and coordinates across UNEP, WHO and FAO.
- Harit Yoga: A Ministry of AYUSH programme that integrates yoga sessions with tree planting to link individual wellness with environmental responsibility.
The WHO-backed One Health framing gives the day a policy hook beyond wellness tourism. UPSC has asked about the constitutional origin of Yoga Day and about AYUSH's mandate.
Revises: International organisations, Ministry of AYUSH, One Health framework.
2. UNCTAD World Investment Report 2025
GS area: GS-III (Investment, External sector, International trade)
UNCTAD released its World Investment Report 2025 showing that global Foreign Direct Investment fell 11 per cent in 2024 to $1.5 trillion. This is the second consecutive annual decline.
- UNCTAD: United Nations Conference on Trade and Development, established in 1964, is the UN body that tracks global investment flows and advises on trade and development policy.
- Global FDI 2024: Fell to $1.5 trillion. The decline was driven by financial restructuring in developed markets and tightening monetary policy in major economies.
- Digital sector exception: Project values in digital-economy FDI doubled even as headline flows fell. This indicates a bifurcation between physical and digital investment trends.
- SDG-sector investment: Fell 25 to 33 per cent. Investment in renewable energy, water, health and food sectors essential for Sustainable Development Goals declined sharply.
- Africa: FDI grew 75 per cent in 2024. This is the strongest regional performer and partly reflects commodity-linked and infrastructure investment.
- ASEAN: FDI rose 10 per cent. Southeast Asia continues to attract supply-chain diversification investment.
- China: Inflows dropped 29 per cent as geopolitical risk and weaker domestic demand dampened investor appetite.
- South America: Declined 18 per cent.
- India: Retained its rank as a top FDI destination with $28 billion in inflows despite the global contraction.
The divergence between India and China on FDI inflows is a recurring MCQ theme. The SDG-sector decline is the normative concern UNCTAD flags every year.
Revises: Balance of payments, FDI policy, international trade institutions.
3. Nuclear Ethics and the Samson Option
GS area: GS-II (International relations, Security), GS-IV (Ethics in international relations)
The escalation between Israel and Iran brought renewed attention to nuclear deterrence doctrine and the ethical frameworks that govern its use.
- Just war theory: Philosopher Michael Walzer's framework divides the ethics of war into two parts. Jus ad bellum covers the conditions for starting a war: just cause, last resort and proportionality. Jus in bello covers conduct during war: discrimination between combatants and non-combatants, and non-combatant immunity.
- Samson Option: Israel's nuclear deterrence doctrine. It is named after the biblical Samson who chose self-destruction along with his enemies rather than surrender. The doctrine signals that Israel would use nuclear weapons as a last resort even at cost to itself.
- Strategic ambiguity: Israel neither confirms nor denies possessing nuclear weapons. This posture is called strategic ambiguity or nuclear opacity. It allows Israel to deter adversaries without triggering a formal nonproliferation crisis.
- Estimated arsenal: Analysts estimate Israel holds between 80 and 400 nuclear warheads. Israel has not signed the Non-Proliferation Treaty and is not subject to IAEA safeguards on its nuclear programme.
- Multi-platform capability: Israel is assessed to have land-based, air-delivered and submarine-launched nuclear options, giving it a second-strike capability.
Strategic ambiguity is a concept that appears in GS-II questions on non-proliferation. Just war theory appears in GS-IV ethics papers.
Revises: Nuclear Non-Proliferation Treaty, IAEA, international security frameworks.
4. Fordow Nuclear Facility
GS area: GS-II (International relations, Security)
The Fordow uranium enrichment facility became central to global security assessments during the Israel-Iran escalation.
- Location: Near Qom in southwest Iran. Fordow is situated approximately 80 metres below ground, reinforced with rock and concrete construction.
- Operational history: The IAEA confirmed Fordow's existence in 2009. Iran had concealed the facility before its disclosure. It enriches uranium to levels up to 60 per cent purity. Weapons-grade uranium requires enrichment above 90 per cent.
- Military significance: The depth and construction make Fordow resistant to most conventional air-delivered munitions. Only the US GBU-57 Massive Ordnance Penetrator is assessed by analysts to potentially penetrate the facility.
- GBU-57 (Massive Ordnance Penetrator): A bunker-buster bomb weighing approximately 13,600 kg. It is designed specifically to destroy hardened underground facilities and is carried by the B-2 Spirit stealth bomber.
- IAEA role: The International Atomic Energy Agency is the UN body mandated to verify that states comply with the Nuclear Non-Proliferation Treaty. It conducts safeguards inspections and issues reports on member states' nuclear activities.
Revises: IAEA, Nuclear Non-Proliferation Treaty, West Asia geopolitics.
