United Kingdom

The United Kingdom has a 1.2% probability of a new armed-conflict onset within 12 months, making this a low risk. Its strong economy, capable state institutions, effective security services, and extensive experience managing political violence constrain escalation, although the country’s history includes the Troubles and other episodes of terrorism and communal conflict.

The recent reporting reviewed contains no specific development indicating an imminent new conflict on UK territory. The principal relevant actors are the UK government, Northern Ireland’s political institutions, and dissident republican or loyalist networks; the key concern would be sustained organised violence rather than isolated attacks.

The largest uncertainty is whether a political or security shock could convert localised violence into sustained armed confrontation, particularly in Northern Ireland. A coordinated campaign involving repeated attacks, mobilisation by armed groups, or severe institutional breakdown would raise risk; durable cross-community political cooperation and effective disruption of militant networks would lower it.
