Description
This introductory course offers a clear, structured overview of the forces reshaping global security in the 21st century. It distils complex issues into accessible insights grounded in my professional experience as a strategic educator, retired senior military officer, and global leadership mentor. The content reflects decades of operational, diplomatic, and analytical work across defence, humanitarian action, and international security.
To ensure clarity, coherence, and learner‑focused delivery, AI tools were used during the development process to assist in drafting lecture outlines, refining structure, and shaping section summaries. Every concept, example, and explanation has been personally reviewed, fact‑checked, and aligned with real‑world cases and professional standards.
Learners gain a foundational understanding of seven interconnected themes that define today’s security environment:
Disinformation and influence operations, and how they undermine trust, polarise societies, and shape political outcomes
Hybrid warfare, where states blend cyberattacks, proxies, economic coercion, and information manipulation to operate in the grey zone between peace and war
Drone warfare, including the rise of loitering munitions, swarms, and the democratisation of airpower
Ethical challenges of lethal autonomy, including human control, accountability gaps, and algorithmic bias
AI and the future of warfare, and the legal, strategic, and governance dilemmas created by accelerated decision cycles
Climate, conflict, and security, exploring how environmental stress multiplies fragility, displacement, and instability
Geopolitics in the 21st century, highlighting shifting power dynamics, technological competition, and the emergence of a multipolar world
The course is designed as a high‑value introduction—concise, globally relevant, and grounded in ethical leadership. It prepares learners to engage more deeply with each topic through the full-length courses, where the frameworks, case studies, and applied analysis are explored in greater depth.
Who this course is for:
- This course is designed for learners who want a clear, structured introduction to today’s complex security environment, including: • Professionals in defence, diplomacy, intelligence, humanitarian action, or peacekeeping
- • Students of international relations, security studies, political science, or technology policy
- • Analysts, journalists, and researchers seeking a concise strategic overview
- • Technologists and innovators working with AI, drones, or digital platforms
- • Anyone who wants to understand how global risks and emerging technologies shape modern conflict
- It is suitable for both beginners and experienced practitioners who want a high level, globally relevant foundation before diving deeper into specialised topics.
