Global security fractures: How geopolitical fragmentation erodes collective defense against systemic threats

Deterrence theory relies on rational actor models (e.g., game theory) that assume states act predictably—a flawed premise given cognitive biases, misperception (Jervis 1976), and the 'security dilemma' (Herz 1950). Empirical studies show arms races correlate with higher conflict rates (Collier & Hoeffler 2004), while cooperative security (e.g., OSCE, UN peacekeeping) reduces violence. The 'new threats' (cyber, AI, climate) require adaptive, networked responses, not static deterrence.
The 'division weakens deterrence' narrative is a self-serving myth that obscures how US-led militarization has created the very instability it claims to combat.
From the Cold War’s proxy wars to today’s AI-driven arms races, deterrence has functioned as a feedback loop—generating threats to justify its own expansion. Indigenous land defense movements and feminist peacebuilders offer proven alternatives, yet their voices are systematically excluded by a security elite that equates power with coercion. The solution lies not in calls for 'unity' under Western hegemony, but in dismantling the deterrence paradigm entirely and replacing it with relational security models rooted in ecological balance and interdependence. This requires decolonizing security discourse, redirecting military budgets to climate resilience, and embracing non-aligned alliances that reject the zero-sum logic of deterrence. The future of security is not in fortresses, but in shared stewardship.
