I agree. The Permissive Action Link(PAL), a remote security device for nuclear weapons, was typically used when the state is non-nuclear, yet is a member of NATO. They are secured and deployed by USAF members. But the UK is not one of these states. In fact, you can find evidence that they do not use the PAL on their own weapons, so most likely they do not have them deployed on any of the NATO nuclear weapons stationed in the UK.
