Defence Minister Chan Chun Sing outlined three key ways that countries are redefining their approach to defence in response to technological and geopolitical changes:
Geographic Boundaries Are Blurring
Traditional geographic concepts of security have become inadequate. As Chan noted, “defence and security can no longer be cut up so neatly based on geography, as per the past.” European ministers now recognize that their security is closely intertwined with that of the Asia-Pacific region, and vice versa. This reflects how threats and security challenges transcend traditional regional boundaries in our interconnected world.
Expanding Beyond Physical Warfare
Defence ministers are no longer focused solely on kinetic warfare (traditional armed combat). They’re equally concerned with securing critical infrastructure, such as underwater internet cables, protecting against information and cyber domain threats, and ensuring the security and resilience of supply chains and economies. This represents a fundamental shift from purely military considerations to broader national security concerns.
Long-term Collaborative Approach
Meeting these complex challenges requires sustained international cooperation across different political cycles. Countries need to collaborate on shared interests, such as securing supply chains and countering disinformation. This has opened new opportunities for Singapore to partner with nations that may be geographically distant but share common security interests.
Chan emphasized that building the necessary capabilities to address these evolving security challenges must be “a commitment across different political cycles,” highlighting the need for consistent, long-term strategic thinking rather than short-term responses.
This evolution in defence thinking reflects how modern security challenges—ranging from cyber threats to economic vulnerabilities—require a more holistic and internationally coordinated approach than traditional military strategies.
Based on Chan Chun Sing’s remarks, here’s an analysis of how countries are redefining defence and Singapore’s strategic positioning:
How Countries Are Redefining Defence
From Geographic to Network-Based Security, Countries are abandoning the traditional model where defence was neatly compartmentalized by borders. Instead, they’re adopting a networked security approach where European security is seen as interconnected with Asia-Pacific security. This represents a fundamental shift from territorial defence to global security interdependence.
Expanding the Security Spectrum, Defence has evolved beyond kinetic warfare to encompass:
- Critical infrastructure protection (underwater cables, internet connectivity)
- Information and cyber domain security
- Supply chain resilience
- Economic security
This broadening means defence ministers now think like national security strategists rather than just military commanders.
Multi-generational countries recognise that building modern defence capabilities requires a sustained commitment across different elements, emphasising institutional continuity over electoral cycles.
Singapore’s Strategic Impact and Positioning
Enhanced Partnership Opportunities The redefinition opens new avenues for Singapore to collaborate with “countries that are farther away but which have shared interests.” This allows Singapore to diversify its security partnerships beyond traditional regional allies, potentially collaborating with nations on specific capabilities such as supply chain security or disinformation countermeasures.
Platform Strategy Over Balance-of-Power Chan explicitly rejected the “balancing characterization between China and the United States. Instead, Singapore positions itself as an “open and inclusive platform” for multilateral dialogue. This approach allows Singapore to:
- Maintain relationships with all major powers
- Facilitate communication without taking sides
- Build trust through institutional frameworks like the Shangri-La Dialogue
Trust-Building Architecture Singapore leverages its role to build multi-level trust:
- High-level political meetings
- Military-to-military exchanges
- Training partnerships
This positions Singapore as a critical node in regional security architecture rather than just a small state managing great power competition.
Long-term Strategic Value: By focusing on capability development and institutional trust-building, Singapore is positioning itself as indispensable to the evolving security landscape—ot through military strength, but through diplomatic infrastructure and partnership facilitation.
The redefinition ultimately enhances Singapore’s strategic relevance by making its diplomatic and institutional capabilities more valuable in an interconnected security environment.
Chan Chun Defence Strategy: Deep Analysis and Singaporean Application
Strategic Framework Analysis
Core Philosophy: Network-Centric Security Architecture
Chan Chun Sing’s defence strategy represents a paradigm shift from traditional territorial defence to what can be termed a “Network-Centric Security Architecture.” This approach recognizes an interconnected world, security threats are multidimensional and transcend geographical boundaries.
Key Strategic Pillars:
- Geographic Transcendence: Moving beyond traditional border-based security to recognize interconnectedness
- Domain Expansion: Extending defence beyond kinetic warfare to cyber, economic, and information domains
- Institutional Resilience: Building long-term partnerships that survive political cycles
- Platform Diplomacy: Positioning Singapore as a neutral convening space rather than a power broker
Strategic Innovation: The “Singapore Model”
The strategy innovates by rejecting zero-sum thinking. Rather than choosing sides or balancing powers, Singapore creates value through:
- Convening Power: Hosting dialogue platforms that build regional trust
- Capability Partnerships: Developing specialized capabilities through selective cooperation
- Information Bridging: Facilitating understanding between different strategic perspectives
- Institutional Memory: Maintaining consistent strategic relationships across political transitions
The Trust Imperative
Chan’s emphasis on multi-level trust-building reflects an understanding that modern security challenges require unprecedented cooperation. This trust architecture operates at:
- Political Level: Ministerial dialogues and summit diplomacy
- Operational Level: Military-to-military exchanges and joint training
- Institutional Level: Sustained partnerships across government transitions
- Civil Society Level: Track-two dialogues and academic exchanges
The Coral Network: A Singapore Story
A fictional account of how Singaporeans might apply these defence principles to emerging threats
Chapter 1: The Invisible War
Dr. Sarah Lim stared at the holographic display in the Cyber Security Command Centre, watching data streams pulse like arterial blood through Singapore’s digital infrastructure. As Director of the National Threat Assessment Unit, she had spent five years preparing for this moment, though she had hoped it would never come.
“Ma’am, we’re seeing coordinated attacks across seventeen different vectors,” reported Lieutenant Colonel Marcus Chen, his voice steady despite the gravity. “Underwater cable disruptions in the South China Sea, social media manipulation campaigns targeting our financial sector, and what appears to be supply chain interference affecting our pharmaceutical imports.”
Sarah nodded, her mind already applying the framework she’d studied countless times—the multi-domain approach that Defence Minister Chan Chun Sing had articulated. This wasn’t just cyber warfare; it was networked conflict across all dimensions of national security.
“Activate the Coral Network protocol,” she commanded. “This is exactly what we trained for.”
Chapter 2: Beyond Borders
The Coral Network—named for its interconnected, resilient structure—was Singapore’s practical application of Chan’s network-centric security philosophy. Unlike traditional defence systems that operated in silos, Coral connected all elements: cyber defenders in Singapore, supply chain monitors in Rotterdam, information warfare analysts in Canberra, and financial intelligence officers in London.
Within minutes of Sarah’s activation order, secure channels opened across four continents. The genius of the system wasn’t its technology, but its trust architecture—relationships built over years of training exchanges, joint exercises, and shared intelligence protocols.
“Singapore Actual, this is Rotterdam Node,” came the Dutch-accented English over the encrypted channel. “We’re seeing similar supply chain disruptions. Our pharmaceutical shipments are being delayed through administrative ‘errors’ at three different ports.”
“London Node confirms financial sector targeting,” the British voice added. “Coordinated short-selling combined with disinformation campaigns about Singapore’s banking stability.”
Sarah smiled grimly. The attackers had assumed Singapore would respond as an isolated city-state. They hadn’t counted on the web of partnerships that Chan’s strategy had carefully constructed.
Chapter 3: The Multi-Domain Response
In the command centre’s situation room, representatives from twelve different agencies worked side by side—not just Singaporean agencies, but liaison officers from allied nations. This was the embodiment of Chan’s vision: security that transcended geography.
“Economic warfare team, what’s our financial resilience status?” Sarah asked.
“We’re implementing the distributed ledger protocols with our Swiss and Hong Kong partners,” replied Director James Wong from the Monetary Authority. “They can’t target what they can’t isolate.”
Meanwhile, the information warfare team was already countering the disinformation campaign. But instead of simply defending, they were applying Chan’s principle of building trust through transparency.
“We’re releasing real-time data on our banking system health through the ASEAN Financial Transparency Initiative,” reported Captain Lisa Tan. “When people can see the actual numbers, the lies become obvious.”
The cyber team took a similar approach. Rather than just defending Singapore’s networks, they shared threat intelligence through the Coral Network, helping partners protect their own systems while collectively mapping attack patterns.
Chapter 4: The Trust Dividend
As the crisis entered its second day, the wisdom of Chan’s long-term relationship building became clear. Countries that might usually compete with Singapore were actively supporting its defence.
“Sarah, you need to see this,” Marcus called out, pointing to his screen. “The Australians just rerouted three cargo ships to bypass the compromised ports. The Japanese are sharing satellite intelligence on the locations of the cable disruptions. Even the Europeans are coordinating their response with ours.”
This wasn’t charity—it was enlightened self-interest enabled by institutional trust. Each partner understood that Singapore’s stability affected their own security. The network effect meant that attacking Singapore required attacking the entire system.
Chapter 5: Beyond Survival
By the third day, the coordinated attack was clearly failing. But Sarah knew that surviving the assault was only the beginning. True to Chan’s philosophy, this crisis presented an opportunity to further strengthen the network.
“Minister Chan’s office is on the line,” her aide announced.
“Sarah,” came the familiar voice of the Defence Minister, “excellent work. But I want you to think beyond just weathering this storm. How do we make the network stronger?”
She had been waiting for this question. “Sir, I formalize the Coral Network protocol for them to any nation willing to commit to the trust-building requirements. This attack demonstrated that isolated defence is obsolete. We need to make network defence the new normal.”
“The institutional memory component is crucial,” Chan agreed. “These partnerships need to survive changes in government, both here and abroad. Make sure the protocols are embedded in treaty-level agreements.”
Chapter 6: The Next Generation
Six months later, Sarah stood before a classroom of young officers from fifteen different nations. The Coral Network had evolved into something unprecedented—a standing multinational defence system that operated continuously, not just during times of crisis.
“The old model of defence was about building walls,” she told the eager faces before her. “But in a networked world, walls become vulnerabilities. The attackers who targeted us assumed we were an island. They discovered we were part of an archipelago.”
One of the students, a young Korean lieutenant, raised her hand. “Ma’am, how do you maintain operational security with so many partners involved?”
Sarah smiled. This was the question she’d asked Chan himself. “Trust isn’t the absence of verification—it’s the presence of accountability. Every partner in the network knows that their own security depends on protecting shared intelligence. Betrayal becomes literally self-defeating.”
Epilogue: The Singapore Model
A year later, the “Singapore Model” had been studied and adapted by nations worldwide. The multi-domain, network-centric approach to defence has proven its worth not just in crisis, but in everyday cooperation on challenges from climate security to space debris management.
Chan Chun Sing, addressing the expanded Shangri-La Dialogue, reflected on the journey: “Singapore never set out to create a new model recognized. We simply recognized that in an interconnected world, isolated security is an illusion. By building trust, sharing capabilities, and thinking beyond traditional boundaries, we discovered that our greatest strength wasn’t our defences—it was our connections.”
The Coral Network continued to grow, not through coercion or alliance structures, but through the simple recognition that in the 21st century, everyone’s security was everyone else’s responsibility.
Strategic Lessons from the Singapore Model
Innovation Through Integration
The fictional Coral Network illustrates how Chan’s philosophy translates into operational capability. By integrating various domains of security and different levels of partnership, Singapore creates resilience that no single nation could achieve on its own.
Trust as Strategic Asset
The story demonstrates how trust becomes a force multiplier. Relationships built during peacetime become operational advantages during crisis, enabling rapid, coordinated responses that individual nations couldn’t achieve.
Beyond Zero-Sum Thinking
Rather than competing for security resources or choosing sides in great power competition, the Singapore Model creates mutual benefit through shared capability development.
Institutional Resilience
By embedding partnerships in formal protocols and cross-generational training, the model ensures that strategic relationships survive political transitions and leadership changes.
The genius of Chan Chun Sing’s approach lies not in any single innovation, but in the recognition that 21st-century security challenges require 21st-century solutions—solutions that transcend traditional boundaries of geography, domain, and political cycle.
