Estonia bets on AI defense while the Vatican and EU debate who should actually use it

Estonia is moving from AI experimentation to defense structuring, leveraging rapid advances in intelligence to offset its small size against the “Russian giant” threat. Since October 2025, the Baltic country has had an AI-focused unit inside the armed forces that tests and organizes innovations for military use. The framing is explicitly strategic: Estonia’s public-sector digitization reputation is being translated into a security posture. The message is that AI is not only a productivity tool, but a force-multiplier that must be operationalized quickly. At the same time, the Vatican’s approach to AI governance is drawing attention for its internal contradictions. Cardinal Michael Czerny, head of the Vatican Commission on Artificial Intelligence, admitted he does not personally use AI despite being four months into a role meant to engage the Church with the AI revolution. This creates a governance optics problem: legitimacy and expertise are being questioned when the institution’s top AI figure does not adopt the tools he is tasked to oversee. In Brussels, the EU’s chief AI adviser Jim Hagemann Snabe urged commissioners to shift from “winning the race” to deploying AI to fix the bloc’s sluggish productivity, positioning AI as an economic and industrial policy lever rather than a prestige contest. Market implications are likely to concentrate in defense-adjacent AI, cybersecurity, and European industrial software. Estonia’s defense AI push can support demand for secure AI systems, edge computing, and intelligence analytics, potentially lifting sentiment around European defense tech and critical-infrastructure cyber vendors. Meanwhile, the EU’s emphasis on deployment over race suggests a policy tilt toward applied AI, which can influence funding flows toward productivity-enhancing platforms in manufacturing, logistics, and administrative services. The Vatican episode may have limited direct market impact, but it can affect regulatory and ethical narratives that shape adoption timelines across Europe’s tech stack. What to watch next is whether Estonia’s military AI unit expands into procurement, doctrine changes, and interoperability with NATO-aligned systems, and whether Russia-linked threat narratives translate into measurable capability milestones. For the EU, the key trigger is how commissioners operationalize the adviser’s guidance—e.g., whether they tie AI funding to productivity KPIs and industrial deployment targets. For the Vatican, the signal to monitor is whether leadership clarifies a practical adoption stance or reframes “not using AI” as a governance principle. Escalation risk is moderate: the more AI becomes embedded in defense workflows, the faster misperceptions and cyber spillovers can propagate, even without kinetic escalation.

Geopolitical Implications

• 01

  AI is becoming a strategic instrument of small-state resilience in the Baltic, potentially accelerating NATO-aligned defense modernization.

• 02

  Divergent institutional stances—operational adoption in Estonia versus personal non-use in Vatican leadership—highlight a governance gap that can shape European adoption timelines.

• 03

  EU industrial policy is reframing AI as an economic security tool, linking competitiveness to deployment capacity rather than model-building alone.

• 04

  Embedding AI into defense workflows increases the risk of cyber spillovers and misperception, even absent kinetic escalation.

Key Signals

• —Estonia: expansion of the AI unit into procurement, field trials, and interoperability with NATO command-and-control systems.
• —EU: commissioner-level adoption of deployment KPIs, regulatory guidance, and budget allocations for applied AI.
• —Vatican: clarification of governance stance on AI use (personal vs institutional) and any resulting ethical/regulatory positions.
• —Cyber: indicators of increased probing or targeting of AI-enabled defense and critical-infrastructure systems in Europe.
