THE LATGALE SALIENT
Rēzekne sits in Latgale, the easternmost Latvian region, less than 60 km from the Russian border and 70 km from Belarus. It is the closest sizable NATO town to the Russia-Belarus seam — a corner of the alliance where any cross-border incident registers first.
ARTICLE 4 vs ARTICLE 5
NATO's treaty distinguishes consultation (Article 4) from collective defence (Article 5). Article 4 has been invoked at least seven times — most recently by Poland after a Russian missile fragment killed two civilians in 2022. Article 5 has been invoked exactly once, after 9/11. The threshold between them is political, not legal.
BALTIC AIR POLICING
Latvia, Lithuania and Estonia gave up their Soviet-era fighter fleets when they joined NATO in 2004. Since then, allied jets rotate through Šiauliai in Lithuania and Ämari in Estonia on four-month tours, scrambling to intercept Russian aircraft over the Baltic. The three states have no fast jets of their own.
THE ATTRIBUTION PROBLEM
Long-range strike drones — Ukrainian Liutyi or Russian Shahed-136 derivatives — share a similar radar profile, fly at similar altitudes, and can drift hundreds of kilometres off-course when jammed. Belarusian and Russian electronic warfare deliberately spoofs GPS across the region, which is why drones aimed at Russian refineries keep landing in Poland, Romania, Moldova and now Latvia.
WHY OIL TERMINALS
Ukraine's deep-strike campaign targets Russian refineries and oil depots to compress fuel margins and federal revenue. The closest cluster to Latgale is around Pskov and Velikiye Luki — within Liutyi range from northern Ukraine, on a flight path that grazes the Latvian and Belarusian borders.
THE PRECEDENT
In November 2022 a Ukrainian S-300 interceptor came down in Przewodów, Poland, killing two farmers. NATO did not invoke Article 5 — investigators concluded the missile was Ukrainian, not Russian, and Warsaw chose Article 4 consultations instead. The episode set the template: even fatal incidents on alliance soil do not automatically escalate.
