Brigade on the Move, 1997 on the Table: Latvia, the Talks and Serbia

The digest has no material updates, but three stories outside it bear directly on NATO's northeastern flank. NATO's multinational brigade in Latvia is starting the largest exercise in its history. The Telegraph reports that Moscow may demand NATO's return to its 1997 footprint. And in Serbia, Aleksandar Vučić has conceded defeat in a parliamentary election.

Latvia: Resolute Reforger 2026 (new WATCH, moderate)

From 26 October to 8 November, NATO's Multinational Brigade in Latvia is running Resolute Reforger 2026, the largest force deployment in the brigade's history: about 3,000 troops and about 1,000 pieces of equipment. Units leave the Ādaži and Ceri bases between 26 October and 2 November and return between 4 and 8 November.

The exercise area covers eastern Latvia: Ogre, Jēkabpils, Aizkraukle, Daugavpils, Alūksne, Balvi, Gulbene, Madona, Rēzekne and Augšdaugava. Latvia's Defence Ministry has warned of heavier military traffic on the roads and helicopters overhead. The brigade commander, Colonel David Brassard, set out the exercise's purpose.

What is confirmed. The name, dates, areas and movement schedule (Delfi, the Latvian Defence Ministry's notice, and the official LV Portāls portal).

What is not established.
- 🟡 The full list of participating countries.

BSM analysis: the Canadian-led brigade is rehearsing a deployment of this size for the first time, and doing it in eastern Latvia, close to the Russian and Belarusian borders. The exercise was planned well in advance and is not a reaction to any specific event. But it coincides with reports that Moscow wants to put NATO's presence in the Baltic states on the negotiating table. Two weeks of convoys on Latgale's roads answer the question "where does NATO stand" without anyone having to say a word.

"The 1997 lines": what Moscow may bring to the talks (WATCH, high potential)

According to The Telegraph on 25 October, as relayed by UNN, Vladimir Putin will probably demand that NATO's footprint in Europe be cut back to its 1997 level, before the former Eastern bloc states joined. The paper reads this as a potential withdrawal of allied troops from Poland, Estonia, Latvia, Lithuania and Finland. Citing anonymous diplomatic sources, it says Moscow wants Europe at the table precisely to extract concessions on NATO.

The public part of the story is confirmed. Kremlin aide Yuri Ushakov has called for Europe to join talks between Russia, Ukraine and the United States. Last week Moscow agreed to technical trilateral talks in Abu Dhabi next month, but Ushakov himself called them a "trial run" and said he expects no significant progress.

What is not established.
- 🟡 The original Telegraph article has not been independently reviewed; its content is given as reported by UNN.
- 🟡 "The 1997 lines" is the paper's forecast based on anonymous sources, not an official Kremlin demand.
- 🟡 The exact date of the Abu Dhabi meeting and the delegations.

BSM analysis: the "NATO-1997" demand is not new as an idea. Moscow put it forward in December 2021, before the full-scale invasion. What is new is how it could now be built into talks about Ukraine. If Europe is invited to the table in order to discuss troops in Estonia or Lithuania, the security of countries that are not party to this war becomes a bargaining chip. For the Baltic states this is the main risk of the current diplomatic cycle.

Forbes: expert opinion, not news (for reference)

The Forbes column of 25 October is analysis. Its central argument comes from Spenser Warren of Harvard's Kennedy School: a US withdrawal from NATO could accelerate Russia's plans and lower the threshold for nuclear use. The Baltic states are named as the most likely targets.

The column cites Danish military intelligence estimates: a local war against a neighbouring country is possible within about six months, a regional war against several Baltic Sea states within about two years, and a large-scale war in Europe within about five. Warren himself says that a quick Russian takeover of the Baltic states without US involvement is "not guaranteed".

• 🟡 The column does not give the date or context of the Danish report. The conclusions on nuclear escalation are expert opinion, not established fact.

Serbia: Vučić concedes (outside the digest)

Serbia held a snap parliamentary election on 25 October. According to a CeSID–Ipsos sample, the student-led list wins 138 of 250 seats and Vučić's Serbian Progressive Party 104; a majority requires 126. Turnout by 18:00 was 64.9%, the highest since the breakup of Yugoslavia. Final results are not yet in.

Vučić conceded that his party had lost. He stepped down as president in September to run for prime minister. The student list is led by cardiologist Ilija Srdanović; who will become prime minister is not yet clear.

European Commission President Ursula von der Leyen and European Council President António Costa welcomed the result and pledged support for reforms on the rule of law, media freedom and anti-corruption. No reaction from Moscow had been recorded at the time of the snapshot. CRTA observers reported pressure on voters or polling staff at almost a third of the 500 polling stations they monitored.

What is not established.
- 🟡 The new majority's foreign policy: the students have said little about Russia, China or the EU. Vučić's claim that sanctions on Russia will come by March or April is his forecast, not a decision.

BSM analysis: Serbia has for years refused to join EU sanctions on Russia, and Russia remains its main gas supplier. A change of government in Belgrade does not yet mean a change of course, but Moscow is losing its most dependable partner in the Balkans. For the northeastern flank this matters for one reason: the fewer governments inside Europe the Kremlin can count on, the harder it becomes to split the European position at the negotiating table.

Conclusion

The digest recorded no material events, but the morning of 26 October fits into one picture. In eastern Latvia NATO's largest brigade-level exercise is heading out on the roads. In Abu Dhabi, talks are being prepared to which Moscow, reportedly, wants to bring a demand about troops in the Baltic states. And in Belgrade the Kremlin is losing a partner it relied on inside Europe. The next snapshot is at 14:00; the next milestone is the Oleshky ceasefire overnight.

Exercises show where NATO stands. Talks will show whether anyone wants it to stand somewhere else.
