Our purpose:

Mission

At the Defence & Strategy Circle, our mission is to shape strategic thinking and policy at the nexus of defence and national security. We connect insight with influence — translating rigorous analysis into actionable solutions for an increasingly contested world.

Defence

We explore the evolving character of warfare — from force posture and capability development to emerging technologies and deterrence strategy — to ensure nations remain ready, resilient, and responsibly armed.

Security

We engage with the grand challenges facing open societies, from geopolitical competition and grey-zone threats to homeland resilience and strategic statecraft, ultimately supporting the stakeholders that protect and uphold them.

Our values

We believe in strategic dialogue and candid conversations in the national interest. Our community is grounded in a commitment to informed, robust analysis — valuing rigour over rhetoric, and insight over ideology. Our endeavours reflect an unshakeable commitment to the national interest. We are a trusted space where ideas are tested, futures are forecast, and security is taken seriously.
