Belgium

Unlikely (around 10–15%) that Belgium will be directly involved in significant armed conflict within the next three years; the main pathway is NATO escalation from the Russia–Europe security crisis rather than domestic instability.

Most likely trajectory is continued domestic contention (strikes, protests) and elevated terrorism/cyber vigilance without armed conflict. Belgium will remain a high-visibility target for influence and cyber operations due to Brussels’ institutional role. Any Belgian military activity is most likely limited coalition deployments, training, air policing, and logistics rather than combat operations.

Risk rises modestly if European deterrence fails or if hybrid campaigns escalate into lethal sabotage against critical infrastructure. Structural constraints remain strong: NATO/EU integration, high state capacity, and lack of separatist armed movements. The most plausible conflict involvement remains alliance-driven participation in a wider European war scenario, not a domestically generated armed conflict.

Net assessment Belgium’s baseline is peace continuity: a wealthy, highly institutionalized EU/NATO state with strong rule-of-law capacity and no active territorial disputes. The main upward risk is external: Belgium is embedded in NATO collective defence and hosts EU/NATO institutions, making it a high-value target in coercion, sabotage, and cyber campaigns during a European crisis.

Threat drivers The Russia–Europe confrontation keeps a tail risk of rapid escalation that could trigger Article 5 dynamics and Belgian participation through air, maritime, logistics, and host-nation support rather than large independent ground operations. Belgium’s role as a hub (Brussels-based institutions, allied coordination, and Benelux connectivity) increases exposure to hybrid pressure: cyberattacks, disinformation, and potential sabotage against transport, ports, energy, and government networks. Persistent terrorism risk and episodic urban disorder add to internal security demands but do not constitute a civil-war pathway.

Resilience and systemic firebreaks Belgium’s security institutions, intelligence cooperation, and alliance integration provide strong deterrence and response capacity. EU/NATO decision thresholds, escalation management, and the high costs of attacking core Western Europe act as major firebreaks. Political fragmentation, strikes, and fiscal-policy gridlock can slow reforms and strain budgets, but they do not meaningfully weaken state monopoly on force in the three-year window.

What would change the score Material upward revision would require clear indicators of imminent NATO–Russia kinetic expansion (sustained cross-border incidents, attacks on NATO territory, or mobilization signals) or repeated successful sabotage causing fatalities and prompting military responses. Absent those rupture signals, Belgium’s most probable security burden remains below the threshold of significant armed conflict: elevated cyber/hybrid activity, counterterrorism operations, and limited coalition deployments.
