Nuclear weapons must not be seen to be vital to the secure defence of self-respecting nations.

Sir, Recent speeches made by the Prime Minister, Foreign Secretary and the previous Defence Secretary, and the letter from Douglas Hurd, Malcolm Rifkind, David Owen and George Robertson in The Times on June 30, 2008, have placed the issue of a world free of nuclear weapons firmly on the public agenda. But it is difficult to see how the United Kingdom can exert any leadership and influence on this issue if we insist on a costly successor to Trident that would not only preserve our own nuclear-power status well into the second half of this century but might actively encourage others to believe that nuclear weapons were still, somehow, vital to the secure defence of self-respecting nations.

This is a fallacy which can best be illustrated by analysis of the British so-called independent deterrent. This force cannot be seen as independent of the United States in any meaningful sense. It relies on the United States for the provision and regular servicing of the D5 missiles. While this country has, in theory, freedom of action over giving the order to fire, it is unthinkable that, because of the catastrophic consequences for guilty and innocent alike, these weapons would ever be launched, or seriously threatened, without the backing and support of the United States.

Should this country ever become subject to some sort of nuclear blackmail — from a terrorist group for example — it must be asked in what way, and against whom, our nuclear weapons could be used, or even threatened, to deter or punish. Nuclear weapons have shown themselves to be completely useless as a deterrent to the threats and scale of violence we currently, or are likely to, face — particularly international terrorism; and the more you analyse them the more unusable they appear.

The much cited “seat at the top table” no longer has the resonance it once did. Political clout derives much more from economic strength. Even major-player status in the international military scene is more likely to find expression through effective, strategically mobile conventional forces, capable of taking out pinpoint targets, than through the possession of unusable nuclear weapons. Our independent deterrent has become virtually irrelevant except in the context of domestic politics. Rather than perpetuating Trident, the case is much stronger for funding our Armed Forces with what they need to meet the commitments actually laid upon them. In the present economic climate it may well prove impossible to afford both.
