World in 10 US nuclear weapons return to Europe
Jul 30, 2025
Dr. Sidharth Kaushal, a Senior Research Fellow at the Royal United Services Institute, breaks down the strategic implications of the US returning nuclear weapons to the UK after nearly two decades. He discusses how this move signals NATO's strengthened nuclear posture against Russia and the role of modern military aircraft like the F-35A in deploying the B-61 nuclear bombs. Kaushal also delves into the international tensions this could exacerbate, particularly in relation to Russian perspectives on US military capabilities in Europe.

Episode notes
Nuclear Return Reflects Shifting Security
- US nuclear weapons returned to Europe after nearly 20 years reflect changed security perceptions due to renewed conventional and nuclear threats from Russia.
- Reintroducing B61 bombs into Europe addresses NATO's concerns over Russia’s tactical nuclear advantage, signaling a tougher NATO nuclear posture.
B61 Bomb's Flexible Yield Capability
- B61 gravity bombs are versatile as they have dialable yields, allowing tailored responses to nuclear threats.
- This flexibility aids policy makers in calibrating responses to low-yield nuclear use, reducing risks of uncontrollable escalation.
F-35s Enhance Nuclear Delivery and Signaling
- The UK’s F-35A stealth fighters enable reliable penetration of Russian defenses, enhancing nuclear delivery options.
- Using aircraft for tactical nuclear strikes helps signal limited escalation rather than all-out strategic war.
