  • The reality of the changing dimensions of warfare

    Why in the News?

    India needs to urgently revamp its defence modernisation plans in the face of emerging challenges from China and Pakistan, especially after the India-Pakistan conflict of May 2025, which revealed gaps in India’s preparedness.

    How has warfare changed since the Cold War?

    • Shift from Large-Scale Wars to Regional Conflicts: After the Cold War, global tensions gave way to smaller, localized wars rather than global showdowns. Eg: The Gulf War (1991) marked the start of precision-based, limited military operations instead of prolonged world wars.
    • Rise of Technology-Driven Warfare: Modern conflicts rely heavily on AI, drones, cyber tools, and precision weapons instead of traditional manpower-heavy combat. Eg: The Russia-Ukraine war has prominently used drones, cyberattacks, and satellite-guided missile systems.
    • Multi-Domain and Asymmetric Warfare: Warfare now involves land, air, sea, cyber, and space, blending conventional and irregular tactics. Eg: The use of cyberattacks alongside physical strikes in Israel-Hamas and India-Pakistan skirmishes reflects this evolution.

    Why is traditional military power becoming outdated?

    • Emergence of Asymmetric Threats: Traditional armies are less effective against non-state actors, insurgents, and cyber warriors who don’t follow conventional battle rules. Eg: The Taliban’s return in Afghanistan despite 20 years of U.S. military presence shows the limits of conventional power.
    • Dominance of Cyber and Information Warfare: Modern conflicts are increasingly fought in the digital space through disinformation, cyberattacks, and AI tools. Eg: The Russia-Ukraine war witnessed widespread cyber sabotage, showing that keyboard warriors can now cripple systems without firing a bullet.
    • Cost-Effectiveness of Smart Technologies: Drones, automated systems, and AI-based surveillance offer greater impact at lower cost than tanks or large troop deployments. Eg: The use of Turkish Bayraktar drones in Ukraine showed how low-cost tech can neutralize expensive military hardware.

    What challenges does India face in countering China’s military rise?

    • Infrastructure Gap along the Border: China has superior military infrastructure in Tibet and Xinjiang, including roads, airstrips, and logistics networks, giving it faster mobilization capability. Eg: The LAC standoff in Eastern Ladakh (2020) exposed India’s slower troop movement due to underdeveloped border infrastructure.
    • Defence Budget and Modernisation Lag: India’s defence spending is lower in proportion to GDP compared to China, limiting rapid modernisation and procurement of high-end military tech. Eg: China’s 2024 defence budget is over 3 times larger than India’s, enabling faster upgrades in hypersonic weaponsand naval expansion.
    • Two-Front Security Challenge: India faces the risk of simultaneous conflicts with China and Pakistan, straining its military resources and strategic planning. Eg: Joint China-Pakistan military exercises and China’s presence in Pakistan-occupied Kashmir (PoK) increase pressure on India’s western and northern fronts.

    How should India update its defence strategy? (Way forward)

    • Focus on Cyber and Space Capabilities: India must strengthen its cyber defence, space surveillance, and satellite-based warfare tools to deal with non-traditional threats. Eg: The formation of Defence Cyber Agency and Defence Space Agency is a step towards tackling emerging cyber and space-based challenges.
    • Promote Indigenous Defence Innovation: Shifting from imports to Make in India and Aatmanirbhar Bharat in defence production is vital for self-reliance and strategic autonomy. Eg: Development of Tejas fighter jets and DRDO’s missile systems shows India’s move toward building its own defence ecosystem.
    • Modernise Armed Forces with Smart Technology: Upgrading with AI-enabled systems, drones, and robotics will enhance operational efficiency in both border and hybrid warfare. Eg: Indian Army’s deployment of drones for surveillance in the LAC region demonstrates the use of tech-driven force multipliers.

    Mains PYQ:

    [UPSC 2022] What are the different elements of cyber security? Keeping in view the challenges in cyber security, examine the extent to which India has successfully developed a comprehensive National Cyber Security Strategy.

    Linkage: The article highlights that “The advent of cyber and Artificial Intelligence (AI) has seen battle elds morph into complex multi-domain conflict zones, involving advanced technologies, AI and cyber warfare methodologies”. It further emphasizes that “digital strategies and autonomous systems are tending to make traditional concepts of how battles are won… outdated” and that “Future warfare is increasingly set to become digitally autonomous and interconnected.

  • Spare live animals, move to biological models

    Why in the News?

    There is growing ethical and scientific concern over the continued use of animal testing in laboratories, as evidence mounts that such methods are often ineffective in predicting human responses. The legal and moral shift in India specifically, an amendment to the Prevention of Cruelty to Animals Act, 1960, to promote the use of bioartificial models over live animals in experimentation.

    What about the Prevention of Cruelty to Animals Act, 1960?

    The Prevention of Cruelty to Animals Act, 1960 is an Indian law enacted to prevent the infliction of unnecessary pain or suffering on animals and to promote their well-being.

    Key features:

    • Prohibits cruelty towards animals such as beating, kicking, overloading, or mutilating them.
    • Establishes the Animal Welfare Board of India (AWBI) to advise the government on animal protection laws and promote animal welfare.
    • Allows for penalties and punishment (fines or imprisonment) for violating its provisions, though critics say these are often outdated and too lenient.

    Why is an amendment to the Prevention of Cruelty to Animals Act, 1960 legally and morally necessary in India?

    • Outdated Penalties and Definitions: The current Act imposes minimal fines (as low as ₹50), which fail to act as deterrents against cruelty. An amendment is needed to introduce stricter punishments and update definitions to match modern ethical standards.
    • Rising Incidents of Animal Abuse: With growing reports of gruesome cruelty (e.g., dog killings, abuse in labs), there is a need for laws that reflect the moral conscience of today’s society and recognize animal sentience.
    • Global Commitments and Standards: India aspires to be a leader in global bioethics and sustainability. Amending the Act would align national laws with international treaties like the Universal Declaration on Animal Welfare, enhancing India’s moral and legal credibility.

    How can regenerative medicine and tissue engineering reduce animal testing?

    • Development of Human-like Organ Models: Scientists can grow 3D human tissues (like liver, heart, or skin) in the lab, which can be used to test drug toxicity and effectiveness. Eg: The “liver-on-a-chip” developed by Emulate Inc. mimics human liver functions and replaces animal use in drug screening.
    • Personalized Disease Models: Patient-derived stem cells can be used to create tissue models that reflect individual genetic profiles, allowing more accurate predictions of drug reactions without animals. Eg: In cystic fibrosis research, mini lungs (organoids) grown from patient cells are used to test responses to various treatments.
    • Accelerated Drug Development and Safety Testing: Tissue-engineered models provide faster and more ethical platforms for early-stage drug testing, reducing the need for preliminary animal trials. Eg: Skin tissue models like EpiDerm are widely used to test cosmetics and chemicals for irritation and toxicity, replacing rabbit skin tests.

    What limitations exist in using animals for toxicity and medical research?

    • Biological Differences: Animals and humans often respond differently to substances, making results less reliable when applied to humans. Eg: A drug safe in mice might cause severe side effects in humans.
    • Inability to Replicate Human Diseases Accurately: Many complex human diseases like Alzheimer’s or cancer cannot be fully mimicked in animals, leading to incomplete or misleading data. Eg: Alzheimer’s treatments successful in animals have failed in human trials.

    Why is a change in societal values crucial for ensuring animal welfare in scientific practices?

    • Shifting Public Opinion Influences Policy: When society becomes more ethically aware about animal suffering, it puts pressure on governments and institutions to adopt humane research standards and fund alternatives to animal testing.
    • Promotes a Culture of Compassion in Science: Changing values encourage scientists to prioritise non-animal methods and view animal welfare as integral to ethical and responsible research, not just a legal requirement.

    What are the steps taken by the Indian government? 

    • Ban on Animal Testing for Cosmetics: In 2014, India became the first country in Asia to ban animal testing for cosmetic products and ingredients.
    • Promotion of Alternative Methods: The government supports institutions like the Indian Council of Medical Research (ICMR) and National Centre for Alternatives to Animal Experiments (NCAAE) to develop in-vitro and computer-based models.
    • Regulatory Reforms: Revisions in Drugs and Cosmetics Rules and CPCSEA guidelines aim to reduce, refine, and replace animal use by encouraging ethical review and stricter compliance protocols.

    Way forward: 

    • Strengthen Investment in Alternatives: Increase funding for regenerative medicine, organoids, and AI-based simulations to provide scalable, ethical, and scientifically advanced testing methods.
    • Enhance Public Awareness and Education: Launch nationwide campaigns to promote animal ethics in science, encouraging academic institutions and industries to adopt humane practices and reduce dependence on animal models.

    Mains PYQ:

    [UPSC 2017] Stem cell therapy is gaining popularity in India to treat a wide variety of medical conditions including Leukaemia, Thalassemia, damaged cornea and several burns. Describe briefly what stem cell therapy is and what advantages it has over other treatments?

    Linkage: The article explicitly advocates for a shift from animal experimentation to methods like tissue engineering or regenerative medicine. Stem cell therapy is a direct application and a significant development within the field of regenerative medicine.

  • Redeeming India’s nuclear power promise

    Why in the News?

    The Union Budget 2025–26 marked a major policy shift by announcing India’s ambitious target of 100 GW nuclear power capacity by 2047, up from the current 8.18 GW. It also allocated ₹20,000 crore for developing five indigenously designed Small Modular Reactors (SMRs) by 2033.

    Why is nuclear energy vital for India’s low-carbon future?

    • Provides Reliable Base-load Power: Unlike solar and wind, which are intermittent, nuclear power offers continuous, stable electricity essential for industrial growth and urbanisation. Eg: In 2024, despite renewables making up nearly 50% of installed capacity, they produced only 240 TWh, while coal contributed 75% of generation due to its reliability. Nuclear can help replace coal-based base-load.
    • Supports India’s Net-Zero and Energy Goals: India has committed to net-zero emissions by 2070, 500 GW non-fossil capacity by 2030, and reducing carbon intensity by 45% over 2005 levels. Eg: Small Modular Reactors (SMRs), with ₹20,000 crore allocated in the 2025-26 Union Budget, are being developed as clean alternatives to replace captive thermal power plants (~100 GW) over two decades.
    • Globally Recognized as Key Low-Carbon Technology: The world is increasingly viewing nuclear energy as essential to climate goals, making it easier to attract investmentand international cooperation. Eg: At COP28 (Dubai, 2023), over 20 countries, including India, endorsed the Declaration to Triple Nuclear Energy, recognizing it as vital to reducing fossil fuel dependency.

    How has past nuclear policy shaped India’s current capacity?

    • Early Vision, Delayed Progress: India had an early start with the establishment of Apsara reactor in 1956 and Dr. Homi Bhabha’s vision of 8 GW by 1980. However, geopolitical events like the 1974 Peaceful Nuclear Explosion (PNE) and India’s refusal to join the NPT (1968) led to international isolation, slowing progress and pushing targets further.
    • Indigenisation of Reactor Technology: Due to technology denial regimes, India focused on developing its own Pressurised Heavy Water Reactors (PHWRs). Starting with 220 MW units, India scaled them up to 540 MW (2005-06) and later to 700 MW (Kakrapar, 2024), building a strong indigenous design and manufacturing base.
    • Limited International Collaboration Post-CLNDA: The 2008 NSG waiver post-India–U.S. nuclear deal enabled resumption of fuel and technology imports. However, the Civil Liability for Nuclear Damage Act (2010) imposed supplier liability, deterring foreign companies. As a result, only Russia has partnered with India at Kudankulam, limiting the scale of international cooperation.

    What hurdles limit private participation in nuclear energy?

    • Restrictive Legal Framework: The Atomic Energy Act, 1962 allows only government entities to operate nuclear power plants. Private companies cannot own or control nuclear facilities, limiting their role to ancillary services unless the Act is amended.
    • Supplier Liability under CLNDA, 2010: The Civil Liability for Nuclear Damage Act places liability not just on the operator (NPCIL) but also on equipment suppliers, making private and foreign companies reluctant to invest due to the high risk exposure.
    • Lack of Financial and Regulatory Clarity: There is no independent nuclear regulator — the AERB is not a statutory body and reports to the Department of Atomic Energy, raising concerns about impartial oversight. Additionally, the absence of a transparent tariff mechanism and nuclear power being excluded from “renewable” status limits access to green financing and incentives.

    Why is an independent nuclear regulator necessary?

    • Ensures Credible and Impartial Safety Oversight: With the proposed entry of private players into nuclear energy, there is a need for transparent and independent safety regulation to ensure public trust and prevent conflicts of interest. The current Atomic Energy Regulatory Board (AERB), though “autonomous”, is not a statutory body and functions under the Department of Atomic Energy, creating institutional dependency.
    • Meets Global Standards and Commitments: According to International Atomic Energy Agency (IAEA) norms, a legally independent regulator is essential to uphold nuclear safety, licensing, and environmental safeguards. This will also improve India’s credibility in international collaborations and foreign investment.
    • Supports Sectoral Expansion with Accountability: As India aims for 100 GW nuclear capacity by 2047, regulatory functions will become more complex, especially with new technologies like Small Modular Reactors (SMRs). An independent authority can better handle licensing, monitoring, safety audits, and dispute resolution without bureaucratic delays.
    • Revives Dormant Reforms: A draft bill to create a Nuclear Safety Regulatory Authority was introduced in 2011 but lapsed. Reviving this reform is crucial to align with the growing scale and diversity of the nuclear energy programme.

    What reforms are needed to meet India’s 100 GW nuclear goal by 2047? (Way forward)

    • Legislative and Regulatory Overhaul: Amend the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010 to allow private sector participation, define clear liability norms, and permit foreign direct investment (up to 49%) while maintaining Indian ownership and control. Establish an independent statutory nuclear regulator to ensure safety and build investor confidence.
    • Financial and Institutional Reforms: Classify nuclear energy as a green energy source to make it eligible for green finance, tax incentives, and viability gap funding. Streamline land acquisition, simplify licensing for PHWR and SMR deployment, and facilitate public-private joint ventures (e.g., NPCIL-NTPC) to scale up infrastructure and domestic supply chains.

    Mains PYQ:

    [UPSC 2023] With growing scarcity of fossil fuels, the atomic energy is gaining more and more significance in India. Discuss the availability of raw material required for the generation of atomic energy in India and in the world.

    Linkage: This question directly addresses the increasing importance of atomic energy in India due to fossil fuel scarcity, which aligns with the nuclear power as a “major pillar in India’s energy mix” for achieving economic growth and “net zero emissions by 2070”.
