Cornerstone of UK and European security

Nuclear deterrence is seen as being the cornerstone of UK and European security. The UK’s own nuclear deterrent is central to this, dedicated to NATO but also the ultimate guarantor of national security. NATO's role as a nuclear alliance is central to its ability to deter nuclear-armed adversaries, most of all (at present) Russia. The government is comfortable with both of these, and would strongly oppose any suggestion that NATO should no longer be a nuclear alliance.
