Background on the UK’s Defense Spending Commitment

The United Kingdom aims to gradually increase its defense spending until it reaches 3% of its Gross Domestic Product (GDP) by the year 2034, according to Defense Secretary John Healey.

Current Spending and Ambitions

Currently, the UK allocates 2.3% of its GDP to defense, a figure that has been criticized by the United States as “frustrating.” To meet Healey’s target, the UK would need to invest an additional £10 billion annually in defense spending, totaling around €11.8 billion.

Prime Minister Keir Starmer previously stated that the UK would dedicate 2.5% of its GDP to defense by 2027, with aspirations to reach 3% by 2034.

Healey’s Firm Commitment

Healey has emphasized that reaching the 3% defense spending target is now a “certainty,” rather than just an “ambition” or wish, as previously suggested by the Prime Minister.

NATO’s Perspective on Defense Spending

These statements come after NATO Secretary-General Mark Rutte expressed belief that member states would agree to invest 5% of their GDP in defense spending during the upcoming NATO summit in The Hague on June 24-25, as proposed by the United States.

The US proposal includes each country allocating 3.5% of its GDP to hard defense budgets, along with an additional 1.5% for defense-related expenses such as military infrastructure.

Former US President Donald Trump had threatened to withdraw the United States from NATO or only protect allies who invested 5% of their GDP in defense. While initially dismissed as unrealistic, most NATO countries have acknowledged the need for significant military investments.

NATO Members’ Compliance

As per NATO’s annual report published in April, only 23 of the 32 member states currently meet the 2014 target of spending 2% of their GDP on defense. However, it is anticipated that all members will comply with this goal by the end of this summer.
