• What: An editorial argues that India has been systematically complying with U.S. unilateral sanctions — on Iran, Venezuela, Russia — at great economic cost. With key waivers expiring (Chabahar port waiver on April 26), India must publicly declare it will no longer abide by them.
• Why in News: The West Asia war (U.S.-Israel vs Iran) has disrupted global energy supply chains. India’s crude import dependence is ~88.6%; the Strait of Hormuz blockade is directly impacting India’s inflation, rupee value, and export figures.
• Key Trigger: India slipped from projected 4th to 6th largest economy (IMF) due to war-induced disruptions. March 2026 exports fell 7%; fertiliser sector contracted 24.6%.

Key Legislations & Frameworks:

• CAATSA (Countering America’s Adversaries Through Sanctions Act): U.S. law threatening secondary sanctions on countries buying Russian military equipment. India purchased S-400 (2018) and faced no penalties.
• JCPOA (Joint Comprehensive Plan of Action): 2015 Iran nuclear deal. India resumed oil imports and signed Chabahar port agreement after this deal.
• OFAC (Office of Foreign Assets Control): U.S. Treasury body enforcing sanctions. U.S. has imposed 365 sanctions this century — the world’s largest sanctioning power.
• Chabahar Port: India-Iran-Afghanistan connectivity project under trilateral agreement. India’s waiver expires April 26, 2026.
• INSTC (International North South Transport Corridor): Multi-modal connectivity route through Iran’s Bandar Abbas.
• PL-480 “Ship-to-Mouth” Historical Parallel: U.S. President Lyndon Johnson’s 1966 “short-tether” policy that used India’s food dependence as leverage — ultimately driving India’s Green Revolution.

Ethical Dimension (GS-IV): India’s compliance with sanctions that target developing nations (Iran, Venezuela) violates the principle of justice as fairness and India’s historical commitment to the Global South. It also weakens the multilateral rules-based order through the UN — a body India has championed.

Federal Concern: Energy price shocks from sanction compliance disproportionately impact state governments managing LPG subsidies, fertiliser supply, and agricultural welfare — creating a centre-state burden-sharing issue.

• What: The two-week U.S.-Israel–Iran ceasefire (announced April 8) is set to expire April 22. Iran claims the U.S. naval blockade of its ports and seizure of a cargo vessel in the Gulf of Oman violates the ceasefire. Tehran is non-committal on joining second-round talks in Islamabad.
• Why in News: The outcome of these talks has direct implications for India’s energy security, shipping costs, airspace reopening, and rupee stability.
• Pakistan’s Role: Pakistan is the mediator. PM Tarar confirmed all arrangements were made, but Iran’s participation was unconfirmed by April 22, 2026 evening.

• Strait of Hormuz: Crucial global oil choke point; handles ~20% of world’s oil supply; jointly blockaded by IRGC and U.S. forces
• JCPOA: 2015 Iran nuclear deal; Trump withdrew 2018; talks to revive it — basis for current diplomatic efforts
• IRGC (Islamic Revolutionary Guard Corps): Iran’s ideological military force; controls Strait of Hormuz blockade
• India’s Exposure: March 2026 crude imports fell 13% from pre-war levels; Middle East imports slumped 61%; Russia imports doubled to fill the gap

• Pakistan as mediator: Raises concerns for India — Pakistan’s role elevates its regional standing while India is sidelined despite being the most impacted non-party economy.
• Rules-based order under stress: U.S. maintaining a naval blockade while in ceasefire sets a dangerous precedent for international maritime law (UNCLOS).
• Iran’s posture: Tehran’s refusal to negotiate under “shadow of threats” reflects sovereign rights — yet prolongs global economic disruption.
• India’s diplomatic silence: India has not formally protested the war’s initiation — a compromise of its stated strategic autonomy doctrine.

• What: India faces an acute gas crisis in 2026 driven by LPG shortages, volatile LNG prices, and soaring import bills — caused by the West Asia conflict disrupting supplies. The article argues that Compressed Biogas (CBG) is the structural solution.
• Why in News: LPG prices spiked up to 5× in cities. India’s LNG imports are projected at 28–29 MMT this year. Domestic gas production meets barely 50% of demand. Energy demand is expected to triple by 2047.
• Current CBG Status: India has estimated potential of 62 MMT of CBG annually, but produces only 920 tonnes/day from 132 plants — a massive execution gap.

• SATAT (Sustainable Alternative Towards Affordable Transportation): MoPNG scheme to procure CBG from entrepreneurs; assured off-take; target: 15 MMT CBG/year by 2023–24 (largely unmet).
• GOBAR-DHAN (Galvanising Organic Bio-Agro Resources Dhan): Converts cattle dung and organic waste to biogas/CBG; supports rural entrepreneurship.
• CBG: Compressed Biogas — purified biogas compressed to >90% methane. Substitute for CNG/LPG. Made from agricultural residues, animal waste, municipal solid waste.
• Ethanol Blending Programme: India achieved 20% ethanol blending in petrol (2025–26) — cited as a model for CBG scale-up.
• Napier Grass: High-yield dedicated energy crop proposed as feedstock for CBG plants.

• What: The Karnataka government proposed awarding grades (instead of marks) for the third language in SSLC exams. The HC ruled this cannot apply to the 2025–26 batch as examinations had already begun (March 18) under the existing marks-based rules.
• Why in News: The judgment reinforces the doctrine of legitimate expectation — students who began exams under one rule set cannot be subjected to a mid-stream change. The government may change rules prospectively (from next year) but not retrospectively for ongoing exams.
• Petitioners: Three students from Chikkamagaluru and Udupi districts.

• Doctrine of Legitimate Expectation: If a public authority creates a reasonable expectation (through policy/representation) that a person will be treated in a certain way, it must honour that expectation unless there is an overriding public interest. Rooted in natural justice.
• Article 14 (Equality before Law): Arbitrary change of rules affecting a defined class of students = potential violation of Article 14.
• SSLC (Secondary School Leaving Certificate): Karnataka’s Class X board exam; governed by Karnataka Secondary Education Examination Board (KSEEB).
• Right to Education (RTE) Act, 2009: Prohibits detention or board exams till Class 8; Class 10 exams are permissible post-RTE.
• Binding Circular: The circular of October 28, 2025 prescribed marks for third language — this was binding for 2025–26. The government’s own advocate had conceded this before the court on April 15.

• Rule of Law vs Administrative Discretion: Governments must act within the framework of their own rules. The state government’s attempt to change assessment mode after exams commenced reflects poor administrative planning.
• Judicial Role in Education: Courts increasingly serve as guardians against arbitrary administrative action in education, especially where student rights are affected.
• Grades vs Marks Debate: While grades can reduce exam stress and align with NEP 2020’s emphasis on competency over rote scoring, the implementation must be prospective and well-communicated.
• NEP 2020 Alignment: The National Education Policy 2020 recommends moving towards holistic assessment — the government’s intent is aligned, but execution was legally flawed.

• What: The first anniversary of the Pahalgam Baisaran meadow attack (April 22, 2025; 26 killed, mostly tourists). Security forces have overhauled tactics: jungle warfare training, 40+ temporary operating bases at 7,000-ft altitudes, Greyhounds deployment, and technology-driven counter-terror.
• Why in News: It offers analysis of evolving terrorist tactics (shift to forest hideouts), India’s counter-insurgency evolution, and lessons for civil services on internal security management.
• Operation Mahadev: Code name for the operation that killed the 3 LeT terrorists (Suleman alias Faizal Jatt, Hamza Afghani, Zibran) in Dachigam forest, 28 July 2025 — after a 60-day 300 sq.km scan.

• Lashkar-e-Taiba (LeT): Pakistan-based terrorist group; designated by UN, India, US; responsible for 26/11 and Pahalgam attack
• Special Operations Group (SOG), J&K Police: Elite counter-terrorism unit; “re-energised” post-Pahalgam with younger officers
• Greyhounds: Elite anti-Maoist force of Andhra Pradesh Police; pioneers in forest counter-insurgency — now deployed in J&K for training
• Pir Panjal & Chenab Valley Region: Rajouri, Poonch, Doda, Kishtwar — areas of increasing terrorist infiltration since mid-2021; 150 security personnel killed in ambushes
• Drone Warfare: Loitering munitions and kamikaze drones being used; congested airspace requiring decentralised control
• UAPA (Unlawful Activities Prevention Act): Key legislation under which terrorist groups like LeT are banned

• Positive Signs: Only 1 local recruit post-Pahalgam; only 5 local terrorists remain with groups — indicates improved counter-radicalisation.
• Ongoing Challenge: ~65 foreign (Pakistan-based) terrorists still active — external infiltration remains a structural problem requiring diplomatic pressure on Pakistan.
• Technology Gap: Dense forests still “pose operational challenges” — indigenous drone counter-measures and navigation systems need faster induction.
• Civilian Safety: Use of armed force in Thoubal (Manipur) highlights the challenge of proportionate force use in civilian areas — applicable in J&K contexts too.
• Federal Coordination: Cross-state training (Greyhounds from AP) and Greyhounds-PARA SF coordination reflects cooperative federalism in internal security.

• What: Japan’s Cabinet approved new guidelines allowing export of lethal weapons — fighter jets, missiles, combat drones, destroyers — to 17 countries with defence agreements. Previously, exports were limited to 5 non-lethal categories.
• Why in News: Signals a fundamental shift in Japan’s post-WWII pacifist identity (Article 9 of Japanese Constitution). Driven by rising China and North Korea threats. Important for Indo-Pacific security and India-Japan defence ties.
• Restrictions: Exports only to 17 countries with defence pacts; National Security Council approval required; will not export to countries at war.

• Article 9, Japanese Constitution: Renounces war and prohibits Japan from maintaining a war potential. Post-WWII (1947) provision. Successive governments have reinterpreted it rather than formally amending it.
• Japan’s Defence Budget: Japan committed to doubling defence spending to 2% of GDP — aligned with NATO standards.
• Artemis Accords: U.S.-led space governance framework; Japan is a signatory. The article draws a parallel between U.S.-Japan military deepening and space governance concerns.
• India-Japan Relations: Special Strategic and Global Partnership (2014); Japan is a key QUAD partner; India is among Japan’s potential export partners.
• Previous Export Limit: Only 5 categories: rescue, transport, alerts, surveillance, minesweeping.

• What: Inherited Peripheral Neuropathies (IPN) affect 1 in 2,500 individuals. Mutations in over 100 genes — including 7 of 37 ARS genes — can cause IPN. Researchers found that only disease-causing ARS mutations show a “dominant-negative” property: the faulty protein doesn’t just stop working but actively blocks the healthy copy too.
• Why in News: Findings published in two papers (2023, January 2026) now offer a therapeutic target — if the mutant mRNA/protein can be blocked, IPN may be treated.
• Research Method: Used budding yeast (Saccharomyces cerevisiae) as a model organism — genetics experiments easier than in human cells.

• Aminoacyl-tRNA Synthetases (ARS): Enzymes that “charge” tRNA molecules with the correct amino acids — essential for protein synthesis. 37 ARS genes exist in humans; mutations in 7 can cause IPN.
• Dominant-Negative Mutation: A mutation where the faulty protein not only loses function but also interferes with the normal protein produced by the healthy gene copy — unlike a “null” mutation which simply produces no protein.
• tRNA (Transfer RNA): Delivers amino acids to ribosomes for protein assembly. Each tRNA carries a specific amino acid, matched by codon-anticodon pairing.
• Dimers: Proteins that must pair up (as two molecules) to function. Dominant-negative effects typically occur in dimer-forming proteins — the faulty copy pairs with the healthy copy, disabling both.
• AARS1 & NARS1: Specific ARS genes studied; encode enzymes for alanine and asparagine attachment to tRNA respectively.
