Historical resilience through prior crises has established a high base rate for continuity. While improbable, rapid shifts could still arise from synchronized national referendums, severe fiscal shocks triggering multiple Article 50 invocations, or an unforeseen external rupture in NATO-EU alignment that accelerates fragmentation pressures.
