National Security Dialogue | Confronting the Enduring Challenges of Counterterrorism in Southeast and South Asia

Terrorism remains one of the most persistent and adaptive threats facing South and Southeast Asia today. The region is witnessing a renewed wave of extremist violence, including lone-wolf attacks, recruitment by transnational jihadist networks, and the reactivation of local militant groups exploiting political instability and social fault lines. From urban terror incidents in South Asia to coordinated attacks in Southeast Asia, these developments highlight the evolving nature of radicalisation and the enduring challenge of preventing violent extremism.

The ideological and operational networks linking groups across the two regions have grown increasingly complex. Extremist movements are drawing on local grievances while aligning with global jihadist narratives, blurring the lines between domestic and transnational threats. These dynamics call for stronger regional cooperation, intelligence sharing, and community-based counter-radicalisation efforts that address both the ideological and socio-economic roots of terrorism.

While traditional forms of terrorism continue to dominate, cyberterrorism and online radicalisation have emerged as significant force multipliers. Extremist groups now exploit digital spaces for recruitment, financing, propaganda, and coordination, extending their reach beyond physical borders. Addressing this convergence between conventional and cyber-enabled threats is now critical to ensuring the long-term stability and security of South and Southeast Asia.

Against this backdrop, the Observer Research Foundation (ORF) has released a special report titled The Enduring Challenges of Counterterrorism: Regional Perspectives from Southeast and South Asia. The report examines how terrorism, radicalisation, and digital vulnerabilities intersect to reshape regional security. Building on its findings, this dialogue seeks to unpack the report’s insights, assess the evolving threat landscape, and explore practical avenues for policy collaboration between South and Southeast Asian nations.

Key Questions for the Dialogue Series

1. How are recent patterns of lone-wolf attacks and the resurgence of local extremist networks reshaping the nature of terrorism in South and Southeast Asia? What factors make these threats particularly difficult to predict and prevent?
2. To what extent do transnational jihadist narratives intersect with local political, ethnic, or religious grievances in South and Southeast Asia? How can governments and civil society actors collaborate to counter these overlapping sources of radicalisation?
3. What role should public–private partnerships, technology firms, and financial institutions play in strengthening cyber resilience and countering online extremism across both regions?
4. As extremist groups increasingly exploit online platforms for recruitment, propaganda, and financing, how should regional governments balance cybersecurity measures with civil liberties? Can cyber resilience be integrated effectively into broader counterterrorism strategies?
