The Eastern Frontline Group is an informal alliance of 43 Members of the European Parliament from 13 EU countries, representing nearly all political groups. Founded in October 2024 by Latvian MEP Reinis Poznaks, EFG works to ensure that the unique challenges of EU states bordering Russia remain a priority on the Union’s political agenda.

Hybrid attacks are no longer isolated incidents. They are constant, deliberate and designed to test the limits of European security. 

From cyberattacks and sabotage to disinformation, drones and attacks on critical infrastructure, these operations operate below the threshold of traditional war — but their cumulative impact is profound.

In this episode of the Eastern Frontline Podcast, MEPs Reinis Pozņaks and Merja Kyllönen speak with Jamie Shea, former Deputy Assistant Secretary General at NATO, about how hybrid warfare is reshaping the strategic landscape in Europe. They explore:

·         What hybrid warfare really means, and why it has become a central tool of modern conflict

·         Why these attacks are becoming more frequent, coordinated and sophisticated

·         The strategic goal of undermining trust, solidarity and political cohesion in Europe

·         The dilemma of escalation: when does a hybrid attack trigger a collective response?

·         Why Europe must move from reactive crisis management to long-term containment

The conversation offers a clear, practical and timely look at the “grey zone” between peace and war — and what it means for European resilience and deterrence.
