Russia Preparing Hybrid Attacks on NATO Eastern Flank

Latvia's intelligence services warned this week that Russia is preparing military provocations against Baltic states or Poland — drone and missile operations designed to pressure NATO. The timing matters: the disclosure came days before a NATO summit focused on eastern flank defense. The question now is whether other alliance members share the assessment, or whether Latvia is sounding the alarm alone.

What Latvian Intelligence Reported

Latvian intelligence agencies issued a warning that Russia is preparing what they describe as hybrid military attacks on NATO's eastern flank. The assessment identifies the Baltic states — Latvia, Lithuania, Estonia — or Poland as targets. The planned operations would involve drones and missiles, designed to test NATO's response capabilities and create pressure on the alliance.

The disclosure came in the final days before NATO convenes to address security along the alliance's eastern border. Latvia shares a 214-kilometer border with Russia and has been among the most vocal members calling for strengthened deterrence in the Baltic region.

The term "hybrid attacks" refers to operations that blur conventional military action and irregular warfare. These can include drone incursions that violate airspace, missile tests near allied territory, cyberattacks on infrastructure, disinformation campaigns, or provocations using irregular forces. The Latvian assessment singles out drones and missiles as particular concerns. What it does not specify: which combination of tactics, or when.

What Remains Unconfirmed

The available reporting confirms Latvian intelligence issued the warning. What it does not confirm: the specific intelligence that led to the assessment. Latvia operates domestic intelligence services and military intelligence units that monitor Russian activity along the shared border and in the Baltic Sea. The country participates in NATO's intelligence-sharing framework. But no direct quotes from Latvian officials appear in available reporting. No intelligence documents. No timelines for when these provocations might occur.

No other NATO member government has publicly corroborated the assessment. Intelligence warnings are often shared privately before being disclosed publicly, but the public silence from Estonia, Lithuania, and Poland is notable. Either the threat picture is uniquely Latvian, or allied governments prefer not to publicize what they know.

Why the Eastern Flank Is NATO's Pressure Point

The deeper issue here is geography. The Baltic states are connected to NATO territory by the Suwalki Gap — a narrow land corridor between Poland and Lithuania fewer than 100 kilometers wide. Any Russian military pressure in this region raises the question NATO has avoided answering clearly: how quickly can the alliance reinforce its northeastern members, and what would trigger that response?

Hybrid attacks create a strategic dilemma. Unlike a conventional military incursion, which would clearly trigger Article 5 mutual defense, hybrid provocations occupy a gray zone. A drone that crosses the border for 90 seconds. A missile test that falls just outside allied airspace. These can probe NATO's response protocols, test political unity among member states, and create uncertainty about when collective action begins.

For Latvia, which hosts NATO battlegroups as part of the alliance's Enhanced Forward Presence, any Russian provocation on its territory would test whether those arrangements are symbolic or operational. The country has consistently argued that the eastern flank requires not just troop presence but fully capable defense systems, including integrated air and missile defense. This warning is part of that campaign.

What the Warning Does Not Tell Us

The assessment leaves critical gaps. No timeline. No indication whether the provocations are imminent or part of longer-term Russian planning. No detail on what intelligence collection method produced the warning — intercepted communications, troop movements, satellite imagery, signals intelligence. These details remain undisclosed.

The scope of potential operations is also unspecified. Would drones or missiles cross into NATO airspace, or operate near the border in ways designed to create ambiguity? Would they target military installations, civilian infrastructure, or serve as demonstrations of capability? The warning does not say.

What To Watch at the NATO Summit

The most immediate test: whether NATO member states address the warning at the upcoming summit. If Latvia's intelligence is shared across the alliance, summit statements may reference heightened vigilance along the eastern flank or announce specific defensive measures. If the summit makes no mention, it suggests either that other allies do not share the threat assessment, or that they disagree on how urgent it is.

Watch for changes in NATO force posture. Deployment of additional air defense systems, increased air patrols, or movement of rapid-reaction forces toward the eastern flank would signal the alliance is taking the warning seriously. On the Russian side, watch for military exercises or equipment movements near Latvia, Lithuania, Estonia, or Poland. Russian forces conduct regular exercises in the Kaliningrad exclave and Belarus, both of which border NATO territory. Unusual activity in these areas would corroborate Latvia's assessment.

Finally, monitor statements from Estonia, Lithuania, and Poland. If they issue similar warnings or call for strengthened defenses, it suggests the intelligence picture is shared. Silence raises a different question: whether the threat is as urgent as Latvia claims, or whether one ally is trying to force the alliance's hand before the summit begins.
