A leaked July 30 letter signed by commissioners from the Baltic states, Poland and Finland points to mounting concern among officials closest to the EU’s exposed northeastern frontier. Reporting on the document says it warned European Commission President Ursula von der Leyen of a “deteriorating security environment,” including more airspace violations and drone incursions. 4

The evidence supports a broader conclusion: Europe is moving toward a long-term eastern-flank security posture that combines national rearmament with EU-level funding, air surveillance, counter-drone capabilities and protection for critical infrastructure. But several of the most specific claims linked to the letter cannot be verified from the material available.
What the letter reportedly signals
The document is significant less because it establishes a single new military program than because of who signed it. The reported signatories included Kaja Kallas, Andrius Kubilius and Valdis Dombrovskis, alongside Polish and Finnish commissioners—senior representatives of countries with direct security concerns on the EU’s eastern and northern edges. 4

According to the reporting supplied, the letter described repeated airspace incidents and drone activity as part of a worsening regional environment. One report also said the incidents were already affecting confidence, but the available material does not provide enough evidence to establish the scale of any business impact or to confirm the full contents of the letter. 5
That distinction matters. The letter is evidence of political alarm and a push for a stronger EU response; it is not, by itself, proof that every figure or policy measure attributed to it has been agreed.
The $115 billion claim is not established by the available evidence
The supplied sources do not verify that the letter requested approximately $115 billion for Baltic defence and economic resilience. Nor do they substantiate the detailed measures described in the question, including rapid responses to energy disruptions, essential-goods stockpiles, shelters, evacuation infrastructure or specific protections against cyber, sabotage, hybrid and electronic threats.
Those proposals may reflect the broader logic of eastern-flank resilience, but the letter itself—or independent corroboration quoting its precise language—would be needed to present them as confirmed contents. The safest conclusion is that the reported document called for stronger EU attention and financing, while the exact amount and package of measures remain unverified.
EU defence spending is rising regardless of the letter
The strategic shift does not depend on the leaked document alone. European Defence Agency data estimates that EU member states spent €418 billion on defence in 2025, equal to 2.2% of GDP, and projects €454 billion in 2026, or 2.4% of GDP. 33
At EU level, the Commission has proposed €131 billion for defence and space in the 2028–34 Multiannual Financial Framework. That is a proposed allocation, not an adopted budget, and it is not evidence that the entire sum would be directed to the Baltic region. 36
European Council President António Costa has also argued that the eastern flank should remain a priority in the next EU budget. Estonia, Latvia and Lithuania have faced repeated air incursions linked to the war in Ukraine, and regional leaders have pressed for security and critical-infrastructure needs to be reflected in future funding decisions. 40
42
The “Drone Wall” is planned—but not yet a proven shield
One important claim in the question is contradicted by the official evidence: the Drone Wall has not been left out of EU planning. Commissioner Andrius Kubilius described the Eastern Flank Watch as centred on a Drone Wall, with advanced detection, tracking and interception capabilities. The wider concept also includes ground defences, Baltic and Black Sea maritime security and space-based situational awareness. 1
The European Parliament has welcomed both initiatives, while warning that an ambitious completion timetable would require rapid implementation. 2 Reporting on the project describes it as a cooperative effort involving Poland, Finland, Estonia, Latvia and Lithuania, intended to strengthen the EU and NATO’s eastern border.

But a policy concept is not the same as a fielded system. The available evidence does not establish the final architecture, cost, staffing model, coverage or number of counter-drone systems required. It also does not substantiate the claim that thousands of short-range systems have already been deployed or that a particular deployment estimate has been agreed.
The practical challenge is therefore clear even if the precise solution is not: a functioning network would require sensors, command-and-control systems, interceptors, trained personnel and coordination across national and EU structures. Current reporting describes the need for a conceptual and technical roadmap, underscoring that implementation remained under development. 3
14
Germany is not shown to be opposing defence spending
The supplied evidence also does not support the claim that Germany is resisting the EU’s security-and-defence priorities. Germany’s 2027 draft budget raises core defence spending from €82.2 billion in 2026 to €109 billion in 2027. 37
There is, however, a real political and fiscal dispute over the size and structure of the next EU budget. Germany and other net contributors have called for reductions to the Commission’s proposed 2028–34 plan, arguing that spending should be restrained or reduced across policy areas. 43
44 That is different from opposing higher national defence spending or rejecting the eastern-flank concern outright.
Rail Baltica highlights the infrastructure problem
Rail Baltica illustrates why security discussions extend beyond weapons and air defence. The project is intended to connect Estonia, Latvia and Lithuania with Poland and the wider European rail network, but its cost estimates have risen sharply—from €5.8 billion in 2017 to €23.8 billion in a later assessment. 19
Its original completion expectations have also changed, with 2030 associated with a first phase and the project’s full timetable remaining uncertain in the supplied reporting. 22
26 These figures do not prove that Rail Baltica is an immediate military-mobility failure, but they show the financing and delivery pressures facing infrastructure that could also have strategic value.
What remains unverified
The supplied material does not independently verify several dramatic claims surrounding the letter and the wider summer warnings, including:
- the precise $115 billion request;
- the complete list of civil-resilience measures allegedly proposed;
- a specific business-confidence effect attributable to the incidents;
- munitions shortages tied to an imminent Baltic confrontation;
- a reported CIA warning following John Ratcliffe’s August 25 Moscow visit; or
- an intelligence assessment of a possible limited Russian incursion in the autumn.
Some supplied reports refer to additional warnings, but the evidence provided here is not sufficient to present those details as established facts. That uncertainty is especially important in a security story, where an alarming headline can easily blur the line between a reported concern, an official proposal and a confirmed operational capability.
Bottom line
The leaked letter’s clearest significance is political: officials from several of Europe’s most exposed eastern and northern states were collectively warning that airspace violations and drone incursions required a stronger EU response. 4
5
The broader policy response is already visible in rising defence budgets, the proposed €131 billion EU defence-and-space allocation, and the Eastern Flank Watch’s Drone Wall concept. 1
33
36 But the letter does not, on the supplied evidence, prove that the alleged $115 billion package, detailed civil-defence measures, intelligence warnings or large-scale counter-drone deployment plans have been agreed.
The defensible reading is therefore neither complacency nor certainty of imminent conflict. It is that Europe is building a more expensive, integrated resilience and deterrence posture on its eastern flank—while the financing, infrastructure and operational details remain contested and unfinished.
