When Defence Minister Rajnath Singh spoke about invisible challenges becoming the focus of his recent speech, it stood out as one of the most important defence statements of 2025.
For me, this was not a ceremonial remark but a wake-up call for the armed forces and policymakers. He warned that the battlefield of tomorrow will not always be visible. Instead, it will be shaped by non-traditional security threats such as information warfare, cyber attacks, ecological disruptions, ideological threats, and biological warfare preparedness.
As a defence enthusiast, I see this shift as India’s move from a conventional defence mindset to a hybrid and multi-domain approach. In this article, I will explain what Singh meant, why it matters, and how India can prepare.
What Rajnath Singh Meant by Invisible Challenges
For decades, India’s defence strategy centred on conventional warfare, fighter jets, tanks, missiles, and naval fleets. But Singh reminded us that today’s security landscape is far more complex.
He pointed to four invisible challenges that are already reshaping global conflicts:
- Information warfare in India: propaganda, cyber manipulation, and perception battles.
- Ecological disruptions and climate security: water scarcity, floods, and climate-induced instability.
- Ideological threats and cognitive warfare: radicalisation, propaganda, and psychological influence.
- Biological warfare preparedness in India: pandemics and CBRN (Chemical, Biological, Radiological, Nuclear) threats.
The scale of these threats is staggering. For instance, CERT-In reported over 2.18 million cybersecurity incidents in 2022, proving that India is already under constant digital attack.
Information Warfare in India: The Silent Battlefield
One of the most critical questions people ask is: What is information warfare in India?
It is the manipulation of information to influence perception. Fake news, deepfakes, and social media propaganda can damage trust in institutions, divide communities, and weaken troop morale.
- Hostile states and non-state actors are already conducting cyber influence campaigns.
- The Russia–Ukraine conflict showed how information dominance can decide wars.
- India must build counter-disinformation strategies, cyber warfare divisions, and critical infrastructure protection frameworks.

Cyber Warfare in India and Critical Infrastructure
Closely linked to information warfare is the threat of cyber warfare in India. A coordinated cyber strike could paralyse power grids, banks, railways, or telecom networks.
- India’s dependence on digital platforms makes it vulnerable to hackers and hostile state actors.
- Strengthening cyber commands, CERT-In coordination, and AI-based defence systems is essential.
- Developing quantum-safe encryption and a zero-trust architecture will future-proof national defence.
Cyber is not just an IT issue anymore. It is a frontline of modern warfare.
Ecological Disruptions and National Security
Another rising query is: How do ecological disruptions threaten India’s security?
Singh stressed that climate change is not just an environmental issue; it is a national security challenge.
- UN reports place South Asia among the most climate-vulnerable regions.
- Water security threats could trigger disputes and migrations.
- Natural disasters like floods and cyclones demand military intervention on a massive scale.
For me, climate security planning must be as central to defence as missile systems or aircraft carriers.

Biological Warfare Preparedness in India
Another question readers ask is: Is India prepared for biological warfare? Lets findout
COVID-19 demonstrated how a small biological agent can paralyse economies and militaries. Singh reminded us that biological warfare preparedness in India is now a national priority.
India must:
- Expand bio-defence research through DRDO.
- Deploy rapid-response CBRN defence units.
- Train the armed forces and integrate with the NDMA and the health ministries.
This is not optional. It is critical to survival in the next crisis.

Ideological Threats and Cognitive Warfare
Another invisible challenge Singh mentioned is ideological warfare.
Cognitive warfare in India is about controlling perceptions, spreading radicalisation, and weakening unity. This is dangerous because it targets the mind and morale rather than the infrastructure.
- Radicalisation campaigns exploit social divisions.
- Propaganda warfare shapes how societies see their own governments.
- India must strengthen counter-radicalisation strategies, civil-military cooperation, and rapid psychological operations.
This is as important as training soldiers in physical combat.
Hybrid Warfare and Multi-Domain Operations
A popular search query is: What is India’s strategy for multi-domain operations?
Rajnath Singh has been clear that India must move from single-domain battles to hybrid warfare.
What India Needs to Do
- Build integrated theatre commands for jointness.
- Expand cyber and space commands and electronic warfare cells.
- Invest in AI-driven systems for faster decision-making.
- Secure the defence industry with supply chain resilience.
- Continue modernisation with Tejas Mk2, Project Kusha, and hypersonic missiles.
India must not only own weapons but also master decision superiority.
Rajnath Singh spoke about invisible challenges: Major Warning?
For me, Rajnath Singh on invisible challenges is not just about the armed forces. It is about national resilience.
India lies in a volatile region, caught between rival powers and global instability. The wars of tomorrow will be fought in cyberspace, in the climate arena, in minds, and possibly in labs.
Preparing for these non-traditional security threats in India is not a choice. It is survival.
Key Takeaways
- Non-traditional threats like cyber, bio, ideological, and ecological risks are as serious as missiles and tanks.
- Information warfare in India is already happening and must be countered with cyber and perception strategies.
- Biological warfare preparedness in India is vital after COVID-19.
- Ecological disruptions and climate security must be part of national defence.
- Hybrid warfare and multi-domain operations will define the future battlefield.
FAQs
Q1. What are the invisible challenges Rajnath Singh mentioned?
They include information warfare, cyber warfare, ecological disruptions, ideological threats, and biological warfare preparedness.
Q2. Why is cyber warfare important for India’s security?
Because attacks on critical infrastructure like banks, power, and telecom can cripple the nation without a single missile being fired.
Q3. How do ecological disruptions affect national security?
Climate change, water scarcity, and natural disasters increase instability and pressure on armed forces.
Q4. Is India prepared for biological warfare?
India is improving bio-defence research, CBRN units, and DRDO medical systems, but more readiness is required.
Q5. What is cognitive warfare?
It is psychological and ideological warfare that weakens unity and morale without direct conflict.
Q6. What is India’s strategy for multi-domain operations?
India is building integrated theatre commands, expanding cyber and space capabilities, and modernising with Tejas Mk2, Project Kusha, and hypersonic missiles.
Final Thoughts: My Perspective
I see Rajnath Singh’s warning as a turning point. The true strength of a nation today lies not only in tanks or missiles but also in its resilience, adaptability, and readiness for invisible challenges.
If India prepares early for cyber defence, bio-defence, climate security, and cognitive warfare, then our armed forces will not just defend borders but also protect the nation from the unseen wars of the future.
