The government says we have to tighten our belts and make massive cuts, but we are actually on the verge of spending our way to disaster. That is exactly what committing £100 billion to building and running a replacement for the Trident nuclear weapons system – as our Government intends – would be: a disaster for all those whose real human needs are not going to be met; those who are now suffering from the harsh effects of cuts to pensions, education, health, public travel provision and even our prison system.
It is not as if "our" nuclear weapons are even really ours. We depend on the United States for the technology, for the missiles, for the guidance systems and even the spare parts. Harold Wilson once said that we have a ‘Moss Bros’ deterrent – just like a suit which we borrow and pretend is ours.
But even if they were really ours, what are they supposed to be for? What is the point of trying to stay in the nuclear weapons game? Field Marshall Lord Bramall, who, as one time head of our armed forces, ought to know, has said: ‘Nuclear weapons have shown themselves to be completely useless as a deterrent to the threats and scale of violence we currently face, particularly international terrorism…’
He is right. The Cold War is long over. The threats we face today are real but none of them can be dealt with by nuclear weapons. Terrorists? Civil Wars? Population movements as a result of climate change? Food and water shortages? Civil unrest leading to riots? Outbreaks of disease? As a matter of history, nuclear weapons – which were supposed to provide ultimate security – did not save the United States from humiliating defeat in Vietnam. They did not stop the Argentinians attacking the Falklands. And they did not help the Soviets in Afghanistan.
Nuclear weapons provide the illusion of security not the reality. Worse, they actually increase the whole world’s insecurity. We all know that every machine operated by humans eventually goes wrong. We are rarely told about the number of nuclear weapon accidents. As recently as 2009, two nuclear armed submarines – one British and one French – collided nearly head-on in the Atlantic. The oceans are littered with up to 20 nuclear submarines as a result of accidents, some with their weapons still on board. The United States once dropped hydrogen bombs in the sea and on the shore of Spain and had to spend fortunes digging up and removing the contaminated soil.
Worst of all are the human technical errors which have several times taken the world to the very edge of disaster. Those who doubt such a claim should read the story of Colonel Petrov who, in 1983, at a time of high East-West tension, "saw" missiles coming from the West to the East. He should have reported this to the Kremlin but, against orders, did not do so, fearful of the consequences. How wise. What he was seeing turned out to be a rare atmospheric condition not missile traces. Had he told the Kremlin that the Soviet Union was under nuclear attack their response might have been catastrophic. We could have been into World War III – a war of no winners.
From a purely British point of view it makes no sense to spend these billions of pounds on what is no more than nationalistic vanity – as any replacement of Trident would be. That’s the message I will be taking to Aldermaston on 1 April  and across the country in my Scrap Trident Tour  over the following weeks. But this is not just a British issue, it is a global one. We need to get rid of all nuclear weapons not just our own.
When we signed the nuclear Non-Proliferation Treaty  in 1968 we promised exactly that. And in 1996, the International Court of Justice said  that there is an obligation to work towards the elimination of all nuclear weapons and ‘bring to a conclusion negotiations leading to nuclear disarmament in all its aspects…’ At the NPT Review Conference in 2000, Britain repeated this commitment.
A perfectly sensible draft nuclear weapons abolition convention , outlining all the steps needed on the way to global elimination, already exists, but Britain refuses to support it. To make sure, by replacing Trident, that we have nuclear weapons for another 40 years is to tell the rest of the world that we do not believe in global abolition. What an incitement to non-nuclear weapons states to take our road.
We humans are perfectly capable of dealing with global problems. Thanks to the World Health Organization smallpox is no longer a threat. We have a treaty, largely observed, against chemical weapons. There is an international agreement on landmines. So too could there be on nuclear weapons if Britain took a positive part.
A final thought. Do we really want to go on indefinitely with a style of "security" based on a willingness to slaughter hundreds of thousands of innocent people elsewhere on the globe if by mistake, accident or miscalculation something goes wrong.
