The way Nato reaches consensus needs reform – and the UK can lead the way

Nato neighbourhoods show us how we can deter Russian aggression in the future.
As the full-scale war in Ukraine enters its fourth year, it is clear that crises in Europe now develop faster than political structures respond. Decisions that could once take days are now needed in hours. Deterrence depends not only on strength, but on the speed it can be brought to bear.
Nato remains the most successful military alliance in history. But its greatest asset, 31 democracies acting together, is also its strategic Achilles heel. Unanimity binds allies politically, yet slows them operationally. Vladimir Putin believes he can exploit that gap. Nato must prove him wrong.
That requires a mindset shift. Not a move away from consensus but a more realistic recognition of where responsibility lies. The Alliance must embrace regional leadership, a “neighbourhood” model where the allies best placed to act in specific theatres are empowered to do so quickly.
This approach is already emerging organically. Nato now needs to formalise it, and the UK should be leading.
Britain’s strategic role is defined by geography. The Greenland, Iceland, UK gap is once again central to Nato's ability to track and deter Russian submarines. That makes the UK indispensable in the High North.
Our capabilities reinforce this role. The Royal Navy Astute‑class attack submarines and the RAF’s P‑8A Poseidon aircraft give Britain first‑rate anti‑submarine surveillance, and the A400M fleet provides heavy‑lift capacity few European allies can match.
British P‑8s have flown joint missions with US and Norwegian aircraft to shadow Russian submarines, and the UK was heavily involved in supporting the US operation against the Russian-flagged tanker Marinera in the North Atlantic.
But leadership isn’t measured by inventories; it’s measured by readiness. Carrier availability, surveillance sortie rates, and the high‑readiness Joint Expeditionary Force (JEF) will determine whether the UK can act as Nato's rapid responder in the High North.
A second example of regional leadership can be found in the Baltic, where the UK is already heavily involved with another JEF nation, Estonia. The Baltic is Nato's most exposed flank, where Russia is most likely to create strategic dilemmas for the Alliance.
For example, how long could Nato take to respond to Russia seeking to occupy an uninhabited island in the Baltic, such as Nooramaa? How many days would pass before Nato considered and mustered a full response to the increased Russian military presence around Narva in eastern Estonia?
These responses might be too slow, and the fait accompli would be that Russian troops now occupied Nato territory. The damage that it would do to Nato is almost unthinkable. But instead, what if there were a “neighbourhood” response through a grouping such as JEF or just a small group of Nato members?
Since 2017, Britain has led Nato's enhanced Forward Presence battlegroup in Estonia under Operation Cabrit, deploying around 900 troops on rotation, including armoured infantry, Challenger 2 tanks and Warrior fighting vehicles. The UK regularly surges additional forces for major exercises and maintains a brigade at high readiness.
Britain’s existing presence in Estonia and Germany’s expanding role in Lithuania together form the backbone of Nato's deterrence on its most vulnerable flank and show why regional leadership works.
If the UK is leading with maritime priorities in the High North and Germany is increasingly active in air defence, Poland is increasingly becoming the land-power centre of gravity for Nato.
With more than 216,000 personnel already in uniform and a legally mandated goal of a 300,000‑strong force, Warsaw is shaping its military around the threat from Russia.
Poland is investing heavily in long‑range fires. Negotiations for 100 HIMARS and a multi‑billion‑pound partnership with South Korea to produce K239 launchers locally will give Poland one of Europe’s largest precision‑strike arsenals. This will make Poland the hinge for Nato's entire eastern posture.
With Britain in the High North and on the ground in Estonia, Germany in the Baltic and involved in air-defence, and Poland in the east, Nato neighbourhoods already exist in practice. Nato must now recognise and institutionalise them.
A light‑touch Deterrence Coordination Centre could map clear regional leadership roles, align industrial plans and streamline crisis‑response mechanisms that allow nations to act quickly. With Britain already heavily involved in Nato neighbourhoods that are developing organically, we should be pushing for the coordination required at Nato HQ to formalise these arrangements and encourage more of them.
This would not weaken collective defence. It strengthens it by making consensus meaningful.
If Nato wants to deter effectively in the decade ahead, it needs to embrace regional leadership, accelerate its decision‑making, and turn speed into its advantage rather than its vulnerability.
