I believe that so long as other countries possess nuclear weapons, the UK should retain an independent nuclear deterrent.
In recent years the UK has become widely recognised as one of the most forward-leaning nuclear weapon states in generating momentum for disarmament. That is a gradual process.
To some, the renewal of Trident may seems a contradictory approach to the UK Government’s overall aim on nuclear weapons. Yet, there is no evidence to suggest that unilateral nuclear disarmament by the UK would encourage any other countries, such as North Korea, to abandon their nuclear ambitions. Nor would it encourage others to disarm any faster. The issue is how we create the right security environment to act as a catalyst for even greater multilateral nuclear disarmament. By signing the Non-Proliferation Treaty, the UK has done more than any other recognised nuclear weapon state to gradually reduce our deterrent.
