NATO Secretary General Mark Rutte has announced that the United Kingdom and Norway have joined alliance operations against Russian submarines in the High North.
In a statement on Thursday, April 9, Rutte said the move aims to disrupt Moscow’s surveillance of critical undersea infrastructure.
“Welcome, UK and Norwegian operations against Russian submarines in the High North,” Rutte wrote in a post on X.
“These efforts to disrupt Russian surveillance of our critical undersea infrastructure protect us all. NATO continues to constantly monitor Russian military activity in the region.”
Russia expands military posture
The announcement comes amid Russia’s growing military capacity despite heavy losses in Ukraine.
President Vladimir Putin has repeatedly signaled hostile intent toward NATO, warning last October that European military build‑ups would force Russia to act.
“Russia’s countermeasures will not be long in coming,” he said at a foreign policy forum in Sochi.
Analysts note that Russia’s ability to threaten NATO depends on three conditions: a ceasefire in Ukraine that would free up forces, the strength of its military, and its perception of NATO’s unity.
Despite sustaining around 1.2 million battlefield casualties, Russia increased its army personnel by 234,000 in 2025 and continues to expand its divisions, brigades, and regiments.
Estonian intelligence has reported a 17‑fold increase in artillery ammunition production since 2021.
Russia has also signed strategic treaties with China, Iran, and North Korea to circumvent Western sanctions, while integrating battlefield lessons from Ukraine into revised doctrines and training.
Western intelligence estimates that once the war in Ukraine ends, Russia could take between six months and five years to rebuild its military for larger aggression.
UK sanctions enforcement challenged
Rutte’s statement followed a direct challenge from Moscow on Wednesday to Britain’s new sanctions enforcement policy.
Earlier this week, the Russian frigate Admiral Grigorovich escorted two sanctioned oil tankers through the English Channel, with a Royal Navy vessel shadowing the convoy.
The Telegraph reported the sighting near Plymouth, marking a defiant response to Prime Minister Sir Keir Starmer’s pledge to crack down on Russia’s “shadow fleet.”
Starmer had authorized British special forces to seize sanctioned tankers transiting UK waters, but no interdiction was attempted during the convoy’s passage.

The Prime Minister has argued that rising oil prices, driven partly by Middle East conflicts, risk providing Moscow with a financial windfall to fund its war in Ukraine.
“Putin is rubbing his hands at the war in the Middle East because he thinks higher oil prices will let him line his pockets,” Starmer said in March.
Russia’s ambassador to London, Andrei Kelin, warned that Moscow would retaliate if the UK deployed military force against sanctioned ships.
“The appropriate measures are being developed. Let this come as a surprise to the British people,” he said.
NATO‑U.S. relations
The developments also come amid strains in NATO‑U.S. relations. Rutte met privately with President Donald Trump in Washington on Wednesday, where Trump expressed disappointment that allies had refused to join the U.S. war against Iran.
Speaking to CNN after the meeting, Rutte described the exchange as “very frank, very open” but declined to say whether Trump raised the possibility of withdrawing from NATO.
“He clearly told me what he thought of what happened over the last couple of weeks,” Rutte said.

Trump has escalated his criticism of the alliance, calling it a “paper tiger” and suggesting the U.S. may consider leaving after member countries ignored his call for military assistance to reopen the Strait of Hormuz.
In a post on Truth Social, Trump wrote: “NATO WASN’T THERE WHEN WE NEEDED THEM, AND THEY WON’T BE THERE IF WE NEED THEM AGAIN. REMEMBER GREENLAND, THAT BIG, POORLY RUN, PIECE OF ICE!!!”
A NATO spokesperson confirmed Rutte’s meeting with Trump, saying the two discussed “a range of issues related to our shared security, including in the context of Iran.”
The spokesperson added that Rutte underscored the importance of allies “continuing to step up to deliver a stronger, fairer Alliance.”
Congress passed a law in 2023 preventing any U.S. president from withdrawing from NATO without approval, but Trump’s repeated criticism has raised concerns about the alliance’s cohesion.
