“F OR ME, I’M living the dream,” says Major Pierre Gosselin, a Canadian company commander in NATO ’s multinational battlegroup in Latvia. A bleak, freezing-cold firing range in January at Camp Adazi, a military base 45 minutes’ drive from Riga, is not everyone’s idea of heaven. But Major Gosselin and his men, recently arrived for their six-month stint here, are loving the camaraderie, testing their weapons and trying out the different models of the small contingent from Montenegro, NATO ’s newest member, which has sent troops to the battlegroup for the first time.

Last July, asked in a television interview why Americans should defend Montenegro from attack, President Trump seemed to question whether NATO ’s mutual-defence guarantee made sense. Montenegrins “may get aggressive”, he said, “and congratulations, you’re in world war three.” The Montenegrins at Adazi, however, are blending in easily. Their leader is particularly impressed by the interoperability of the magazines.

The Canadian-led battlegroup is one of four that NATO has deployed since 2017 as part of its “enhanced forward presence”; the others are in Estonia (under British leadership), Lithuania (led by Germany) and Poland (where America takes the lead). The battlegroup in Latvia is the most international of the four: nine countries contribute to its 1,400-strong force. Colonel Josh Major, the commander of Task Force Latvia, calls it a “pretty good representation of all of Europe”. His forces have been involved in outreach activities all over the country, helping to counter Russian efforts to discredit NATO ’s presence there. It’s been a “great experience for all our troops”, he says.

But they are not there to have fun. Their job is to change the calculus in Russia, making any incursion much costlier to an aggressor. “The closer you get to Latvia, the more the sense of threat becomes real,” he notes. Part of this is a reflection of history. At the Latvian War Museum in Riga a new exhibition marks the centenary of the country’s war for independence, hard-won with help from allies including Britain and France. But in 1940 the Latvians allowed the Russians in without a fight, and then lived under Soviet occupation for half a century. Next time, if there is one, they are determined to shoot.

In 2014 Russia provided a fresh reason for Latvians to feel threatened: it invaded Ukraine, with devastating speed, surprise and the use of “hybrid” tactics involving disinformation and disguised troops. It is all too easy to imagine how the same tactics could be applied in the Baltics. “War with Russia”, a novel by General Sir Richard Shirreff, describes exactly such a scenario, drawing on his experience at NATO , where he served as deputy supreme allied commander for Europe.

The Latvians and their Baltic neighbours are also on their guard because Russia has been building up its forces near their borders in recent years. Russian military modernisation has reached a stage, says Rose Gottemoeller, NATO ’s deputy secretary-general, “where we have to be hyper-alert”.

Land, sea and air

That is why NATO has enhanced its presence not only on the ground but also in the air. At Amari in Estonia it has added an extra arm of its Baltic air-policing operation (the leading part of it remains in Lithuania). NATO countries take turns to do four-month stints at Amari; currently the Germans are there. Twice a day two of their Eurofighters are in the air within 15 minutes of the siren sounding. Once or twice a week these are live interceptions, typically of Russian planes flying between St Petersburg and the enclave of Kaliningrad. The interceptors get close enough to identify the Russian planes, but without provoking them.

NATO ’s presence in Adazi and Amari is just a start. Some would like to see both missions beefed up to convert the Baltic air policing into air defence and to enlarge the battlegroups and make them permanent. Radek Sikorski, a former Polish foreign minister, calls the Baltic battlegroups “symbolic”.

So keen is the current Polish government to host a bulkier American force that it has offered to pay the United States about $2bn to set up a permanent base. Poland’s European allies frown on such bilateral deals, which are at odds with NATO ’s collective spirit. Critics fear the move could divide the alliance and provoke Russia. Polish officials are confident of getting a beefier American presence in return for “enhanced host-nation support”, stressing that they see this as a regional hub benefiting NATO .

NATO has plenty on its plate implementing the decisions it has already taken. The credibility of its forward presence depends on having reinforcements ready and being able to deploy them rapidly to prevent Russia from creating a fait accompli in the Baltic states. Simply clearing away obstacles to moving troops across Europe is a big task.

This is not just about NATO ’s eastern front. The alliance needs to be able to respond to threats wherever they may arise. “The alliance has got to get the initiative back, rather than always reacting to Russia,” says Lieutenant-General Ben Hodges, a former commander of the US army in Europe, now at the Centre for European Policy Analysis ( CEPA ), a think-tank.

Recently Russia has been flexing its muscles in the Black Sea region. In November it seized three Ukrainian navy ships trying to cross, as they are entitled to do, from the Black Sea to the Sea of Azov via the Kerch Strait. Mr Hodges worries that NATO has not paid enough attention to the area. Russia’s actions have now brought a fresh focus on it.

NATO ’s individual members have different perceptions of potential threats. Whereas the Baltic countries are alert to any change in the wind from Russia (“We feel it on our skin,” says Latvia’s defence minister, Artis Pabriks), what Greeks feel on their skin is menace from Turkey, a fellow NATO member. Italians are less worried about Moscow than about migrants crossing the Mediterranean. The French concentrate especially on efforts to stabilise former colonies in Africa. And the Germans seem to feel threatened mainly by the thought that if NATO and the EU were to collapse they would lose the cornerstones of their stability and prosperity.

To accommodate these diverse interests, the allies have developed what they call a 360-degree approach to security. That involves tackling threats not just from Russia but also from north Africa and the Middle East, sources of migration and terrorism. This has bolstered solidarity among NATO members. It is why Canada is happy to lead a training mission in Iraq and why Latvians have fought and died alongside Americans in Afghanistan.

But this inclusive approach has its problems. One is that NATO may try to do too much and lose focus on its core mission of defence against Russia. Another is that, though speed is of the essence, decisions get gummed up in a search for consensus among 29 countries. Efforts to cut through this by granting more autonomy to NATO ’s military chief, the supreme allied commander for Europe, meet resistance from members wary of ceding sovereignty.
