‘World has changed’: Starmer plans UK army ready to fight in Europe to give message to Putin, Trump

The United Kingdom will build new nuclear-powered attack submarines, prepare its army to fight a war in Europe, and become “a battle-ready, armor-clad nation,” Prime Minister Keir Starmer said Monday, as part of a military spending hike intended to send a message to Moscow and Washington.

Starmer said Britain “cannot ignore the threat that Russia poses” as he vowed to make the most significant upgrades to Britain’s defences since the Soviet Union’s collapse more than three decades ago.

“The threat we face is more serious, more immediate, and more unpredictable than at any time since the Cold War,” Starmer told workers and journalists at a naval shipyard in Scotland.

A new era of threats

Like other Nato members, the UK has been reassessing its defense spending since Russia’s full-scale invasion of Ukraine in February 2022.

The government announced military plans in response to a strategic defense review commissioned by Starmer and led by George Robertson, a former U.K. defense secretary and Nato secretary general. It’s the first such review since 2021, and lands in a world shaken and transformed by Russia’s full-scale invasion of Ukraine in 2022, and by the re-election of President Donald Trump last year.

Months after Britain’s last major defense review was published in 2021, then-Prime Minister Boris Johnson said with confidence that the era of “fighting big tank battles on European landmass” are over. Three months later, Russian tanks rolled into Ukraine.

Starmer’s center-left Labour Party government says it will accept all 62 recommendations made in the review, aiming to help the U.K. confront growing threats on land, air sea and in cyberspace.

Submarines and weapons

The measures include increasing production of submarines and weapons and “learning the lessons of Ukraine,” which has rapidly developed its drone technology to counter Moscow’s forces and even hit targets deep inside Russia.

The government said the U.K, will also establish a cyber command to counter “daily” Russia-linked attacks on Britain’s defenses.

Monday’s announcements include building “up to 12” nuclear-powered, conventionally armed submarines under the AUKUS partnership with Australia and the United States. The government also says it will invest 15 billion pounds in Britain’s nuclear arsenal, which consists of missiles carried on a handful of submarines. Details of those plans are likely to be kept secret.

The government will also increase conventional Britain’s weapons stockpiles with up to 7,000 U.K.-built long-range weapons.

Starmer said rearming would create a “defense dividend” of thousands of well-paid manufacturing jobs — a contrast to the post-Cold War “peace dividend” that saw Western nations channel money away from defense into other areas.

Deterring Russia comes at a cost

Defense Secretary John Healey said the changes would send “a message to Moscow,” and transform the country’s military following decades of retrenchment, though he said he does not expect the number of soldiers — currently at a two-century low — to rise until the early 2030s.

Healey said plans for defense spending to hit 2.5% of national income by 2027 a year are “on track” and that there’s “no doubt” it will hit 3% before 2034.

Starmer said the 3% goal is an “ambition,” rather than a firm promise, and it’s unclear where the cash-strapped Treasury will find the money. The government has already, contentiously, cut international aid spending to reach the 2.5% target.

Starmer said he wouldn’t make a firm pledge until he knew “precisely where the money is coming from.”

Even 3% falls short of what some leaders in Nato think is needed to deter Russia from future attacks on its neighbors. Nato chief Mark Rutte says leaders of the 32 member countries will debate a commitment to spend at least 3.5% of GDP on defense when they meet in the Netherlands this month.

Bolstering Europe’s defenses

It’s also a message to Trump that Europe is heeding his demand for Nato members to spend more on their own defense.

European countries, led by the U.K. and France, have scrambled to coordinate their defense posture as Trump transforms American foreign policy, seemingly sidelining Europe as he looks to end the war in Ukraine. Trump has long questioned the value of Nato and complained that the U.S. provides security to European countries that don’t pull their weight.

Starmer said his government would make “Britain’s biggest contribution to Nato since its creation.”

“We will never fight alone,” he said. “Our defense policy will always be Nato-first.”

James Cartlidge, defense spokesman for the main opposition Conservative Party, welcomed more money for defense but was skeptical of the government’s 3% pledge,

“All of Labour’s strategic defence review promises will be taken with a pinch of salt unless they can show there will actually be enough money to pay for them,” he said.
