As the senior program coordinator for the McCain Institute’s National Security & Counterterrorism Fellowship (NSCT), I had the privilege of joining the 2024 cohort for its final module in the United Kingdom. This experience highlighted the critical role of leadership in shaping national security professionals’ capabilities and reaffirming the importance of robust partnerships within the Five Eyes national security alliance.
Leadership in the Five Eyes Alliance
The weeklong module in London and Belfast provided a unique platform for the NSCT Fellows from the Five Eyes alliance to engage with senior national security leaders, discuss shared security challenges, and reflect on the leadership qualities required to navigate these complexities. Through candid discussions and immersive experiences, we explored how leadership is not just a skill, but a mindset essential for addressing today’s dynamic and interconnected threats.
One of the module’s most significant aspects was its focus on the enduring strength of the Five Eyes, a cornerstone of international security cooperation. The partnership between Australia, Canada, New Zealand, the United Kingdom, and the United States goes beyond intelligence-sharing; it embodies a commitment to collective problem-solving, trust, and resilience.
In London, the fellows engaged with officials who underscored the alliance’s critical role in countering emerging threats like cyberattacks, terrorism, and geopolitical instability. This alliance is vital in addressing multifaceted challenges that transcend borders, ensuring no single nation bears the burden of security alone.
Historical and Regional Contexts
The United Kingdom’s rich history in counterterrorism provided an unparalleled backdrop for exploring leadership. Visiting historical landmarks to reflect on the legacy of figures like Winston Churchill reinforced the enduring relevance of character-driven leadership. Churchill’s resilience and vision during national crises reminded us that great leaders inspire through their ability to articulate a shared purpose and rally others to action.
Our time in Belfast added nuance to these lessons. A city shaped by decades of political conflict and reconciliation; Northern Ireland offered a powerful perspective on leadership in navigating societal divisions. The balancing act of pragmatism and long-term vision seen in Belfast’s history paralleled many discussions we had throughout the fellowship, highlighting how leaders must manage competing priorities while staying focused on overarching goals.
Learning from Exemplary Leaders
During the module, we had the opportunity to meet with leaders from agencies such as MI6, the Joint Terrorism Analysis Centre, and the Foreign, Commonwealth & Development Office. These leaders shared personal insights on managing national security priorities while fostering trust, collaboration, and resilience.
A recurring theme was adaptability. As one security official put it, “The world doesn’t wait for us to catch up—it demands action, creativity, and resilience.” This lesson resonates as we consider the rapidly evolving threats of cyberattacks, terrorism, and geopolitical tensions. Effective leaders must think beyond traditional frameworks, anticipate challenges, and innovate solutions.
Authenticity also emerged as a cornerstone of effective leadership. Whether managing crises or guiding long-term strategies, staying true to one’s values fosters trust and credibility. This authenticity enables leaders to navigate uncertainty while maintaining the confidence of their teams and stakeholders.
The NSCT Fellowship provided unparalleled access to security leaders across the Five Eyes governments. Their generosity in sharing knowledge, reflecting on lessons learned, and openly discussing the challenges that contributed to their growth not only encouraged deeper consideration of leadership development but also instilled confidence in fostering positive change within professional environments.
Building an Enduring Network
The London module also strengthened the bonds within the NSCT cohort. As a group of 16 fellows from diverse professional and cultural backgrounds, they brought unique perspectives to the table. Through shared discussions, challenges, and reflections, they built a network of peers committed to collaboration and mutual support.
This network is one of the most enduring aspects of the fellowship. Grappling with the complexities of national security, the fellows discovered the value of teamwork and shared purpose. As one fellow aptly stated, “The United Kingdom’s unique history with counterterrorism and national security issues provided a fantastic strategic backdrop that drove salient conversation with our cohort and senior government officials.” The lessons they learned from one another will undoubtedly shape their work as national security professionals for years to come.
Moving Forward
The London module underscored the vital role leadership plays in shaping national security outcomes. The insights gained during this experience are not confined to theory; they serve as practical tools for fostering collaboration, navigating ambiguity, and leading with integrity, empathy, and adaptability.
The NSCT Fellowship’s London module served as a capstone for the 2024 cohort’s year-long development as emerging leaders. As the program prepares to welcome the 2025 cohort, these lessons will continue to guide efforts to empower the next generation of global leaders.
Leadership in national security is not just about managing crises; it is about inspiring others, building trust, and staying true to core values. The journey of leadership is one of continuous growth, reflection, and action—an essential foundation for creating a safer, more secure world.
