Swedish Chief of Defence Calls for European Nuclear Deterrence Amid Rising Security Threats

Michael Claesson, Sweden's Chief of Defence, has voiced strong concerns about Europe's security landscape, highlighting the urgency for Europe to develop its own nuclear deterrent independent of the United States. Speaking in recent interviews, Claesson underlined the deteriorating security situation due largely to ongoing threats from Russia, emphasizing that Europe's current reliance on US nuclear protection is insufficient for future challenges.

Claesson pointed out that Europe's nuclear powers—primarily the UK and France—possess over 500 nuclear warheads in total, far fewer than the 5,000-plus held by both the US and Russia. Despite this, he stressed the importance of European allies contributing more significantly to nuclear capabilities through "dual-use" deterrence strategies, which would require formal and substantial military build-up.

He also highlighted the broader need for improved European defense capabilities, including air refueling, command, intelligence, and space operations, acknowledging that Europe has some capacities but still lags behind the comprehensive US arsenal. Claesson did not specify exactly how Europe might develop this nuclear deterrent, whether by collaborating with existing nuclear nations or pursuing new avenues, but insisted it was imperative given the existential threat posed by nuclear weapons in the current environment.

In his own words, Claesson remarked, "I support the notion that this is a very serious security situation overall, and there is still room for various outcomes." He concluded that establishing a credible European nuclear deterrent would necessitate formal steps and a significant strengthening of Europe’s defense posture to effectively counter emerging security risks.
