EU Confronts Russian-Linked Security Risks: Threat Assessment and Expanded Advisory Mission to Ukraine

5/19/2026, 11:29:37 PM

EU Threat Assessment Highlights Russian Spillover Risks

A 23-page internal threat assessment by the Council of the European Union for 2025 states that terrorism and violent extremism ‘pose a significant threat to the EU.’ It finds the war in Ukraine has limited impact on terrorist activity but warns that the flow of small arms, light weapons and explosives, sabotage of critical infrastructure and UAV use could raise medium-term risks, such as UAVs with radioactive material. The document also flags the possible return of Russian ex-combatants.

Background: War in Ukraine and EUAM

Since Russia’s full-scale invasion in February 2022, the EU has increased security cooperation with Kyiv. The EU Advisory Mission to Ukraine (EUAM), launched in 2014 after Euromaidan, supports Ukrainian police. In May 2025 the EU approved an expansion of EUAM’s mandate to address hybrid threats and to aid veteran reintegration.

Key Numbers

The assessment notes roughly 1.5 million Russian citizens have fought in Ukraine, with about 640 000 still active and 180 000 early-released prisoners deployed. Russia’s crime rate hit a 15-year high in early 2025, linked to returning ex-combatants. EUAM employs close to 400 staff and has a €123 million budget rising to €130 million after expansion. The Schengen entry-ban would apply for five years to all EU members except Cyprus and Ireland and to Iceland, Liechtenstein, Norway and Switzerland.

Official Statements & Responses

EU foreign ministers are preparing a Schengen blacklist that would bar identified Russian ex-soldiers from entering the zone for five years. The expanded EUAM mandate will help Kyiv protect critical infrastructure, enhance cyber security, counter information manipulation, and integrate war veterans into civilian security services.

Criticism & Opposition

Member states lack a common EU definition of sabotage as terrorism, hampering coordinated action. Although the assessment warns of UAV attacks with radioactive material, none have been recorded in the EU. Enforcing the Schengen ban will depend on consistent intelligence sharing, a capacity that varies across the bloc. The document’s note that the war’s terrorist impact is limited adds uncertainty to future risk forecasts.

Verbatim Quotes

  • “It notes that terrorism and violent extremism "pose a significant threat to the EU," citing heightened risks from Afghanistan and Iran.” — Council of the European Union internal document
  • “impact of Russia's war of aggression against Ukraine on the terrorist threat both in Europe and globally has so far been limited.” — Council of the European Union internal document
  • “likely that the flow of small arms, light weapons and explosives in particular will have consequences in the medium and long term.” — Council of the European Union internal document

Outlook

EU foreign ministers are expected to adopt the Schengen entry-ban in June, while EUAM’s expanded activities are slated to start this summer. NATO foreign ministers will meet in Helsingborg, Sweden, on 21-22 May, where the implementation of these measures will be closely watched.
