UK and France Strengthen Nuclear Cooperation
Recently, British Prime Minister Kiel Starmer and French President Emmanuel Macron signed the Northwood Declaration, which aims to enhance nuclear collaboration. The plan includes the establishment of a British nuclear steering group, set to provide political guidance and coordinate nuclear policy, capacities, and operations.
This agreement comes amid increasing concerns about Russia under Vladimir Putin, which has been seen as a significant security threat to Europe, reminiscent of the Cold War. There’s a growing belief that America’s commitment to NATO might not be as solid as it once was.
Each nation’s updated national security strategies reflect these fears. The UK released its Strategic Defence Review on June 2, while France followed suit with its national strategic review on July 14, coinciding with Bastille Day. Both documents share similar language regarding the Russian threat.
This isn’t the first time that the UK and France have committed to closer collaboration on nuclear matters. Historical agreements, like the 1995 Checkers Declaration, indicated that threats to one nation’s vital interests are threats to both.
However, despite some advancements since 2010, the strategic nuclear relationship between the UK and France hasn’t changed much in the past 30 years, largely due to differing deterrent capabilities.
The UK’s nuclear deterrent has been closely tied to the US since the 1950s, governed by the Mutual Defense Treaty of 1958, which facilitates the transfer of classified nuclear information and technology from the US to the UK. This treaty continues to shape how the UK operates its nuclear program.
The history around this is intricate. In December 1962, then Secretary of Defense Robert McNamara described independent nuclear capabilities as costly and potentially outdated, leading to concerns in Britain about its reliance on American support. Prime Minister Harold Macmillan sought to maintain Britain’s autonomy in nuclear matters but faced limitations, especially given the long-standing treaty restrictions that affect collaboration with France.
In contrast, France’s approach to nuclear power has been distinctly independent. The French deterrent focuses more on threats directly against France and has pursued a different strategy, unlike the UK’s commitment to NATO defense.
Amid uncertainty regarding the US’s dedication to NATO, Macron suggested that France might broaden its nuclear protection. This could align with the UK’s strategy, signaled by the establishment of the French-German Security Council, while emphasizing that France would retain final authority over its decisions.
Both nations have also deployed nuclear submarines in response to perceived threats from Moscow, as tensions over Ukraine continue. The Kremlin has likely noticed these military developments, potentially leading to increased tensions.
However, both countries remain cautious about going it alone in the nuclear realm without American backing. Their nuclear arsenals are significantly smaller compared to Russian and Chinese forces.
Despite the restrictions imposed by the 1958 treaty, it’s apparent that the UK and France are edging closer to genuine strategic nuclear coordination. The Northwood Declaration might have implications that surpass earlier agreements. Their combined deterrent could send a strong message in support of Ukraine.
Ultimately, though, it’s the US’s nuclear deterrent that remains central to NATO’s strategy. Thus, sustaining Washington’s commitment to the alliance and ensuring its nuclear support is as crucial now as it was during the early Cold War.
