Continuous At-Sea Deterrent

Debate between Ronnie Cowan and Julian Lewis

Wednesday 10th April 2019 Commons Chamber

[Dr Julian Lewis (New Forest East) (Con)]

I am delighted to follow two such supportive speeches on the nuclear deterrent and the work of those who have crewed it for the past 50 years. It is amazing to think of the combination of high training and long periods of low activity that such personnel have to undergo. They truly are the silent guardians of the country and we are hugely in their debt.

What is more, most Members of this House recognise that fact. It is worth putting on the record that in recent years the House has had two key votes on the question of the renewal of the nuclear deterrent submarine fleet, the first under the Labour Government of Tony Blair on 14 March 2007. The House voted by 409 to 161—a massive majority of 248—to proceed with the initial gate of the replacement or successor submarine fleet. The second was under the Conservative Government of the current Prime Minister on 18 July 2016, when the House voted by a colossal majority of 355—namely, 472 votes to 117—to proceed to the main stages of development and production of the submarines.

The only issue to which I took a little exception in the contribution of the shadow Defence Secretary, the hon. Member for Llanelli (Nia Griffith), was in one turn of phrase, when she said how appalling it would be if the deterrence weapons were used. I remind her gently that the nuclear deterrent is in use every day of every week all around the year, because the purpose of the nuclear deterrent is to ensure that nuclear war does not break out because no one is in a position to attack us with impunity.

[Ronnie Cowan (Inverclyde) (SNP)]

In the right hon. Gentleman’s description of the deterrent, will he explain why none of the missiles is actually targeted at any targets?

[Dr Lewis]

It is for the simple reason that, in the unlikely event of anyone being mad enough to attack us—because we have the ability to retaliate—it would be simple to target missiles to retaliate against them, and that could easily result in the obliteration of any country unwise enough to launch a nuclear attack against a nuclear power such as ourselves.

[Ronnie Cowan (Inverclyde) (SNP)]

When I rose to make my maiden speech on 1 July 2015, I touched on the Trident programme, because it is close to my heart. In fact, it is very close to my constituency. At the time, I mentioned that Trident seemed to be a bit of an abstract concept. People know it is out there, but they do not know what it is, how much it costs, how much it cannot be used and what it is actually doing as a deterrent.

If people stand on the shore of my constituency, they will often see Vanguard class submarines moving silently through the deep waters. They catch the sunlight, which shimmers along their long, sleek, black bodies as they cut through the surface of the water. Their colour may suggest giant eels, but they lack the elegance. They are, however, engineering marvels. It takes some doing to fire a missile from beneath the water’s surface, project it through the water until it breaks free, and manage two controlled explosions that project the missile to a pre-defined target where ballistic missiles carrying nuclear warheads are released and either explode on impact or are exploded automatically at the required height to cause maximum death and destruction. Mankind has never lacked ingenuity when it comes to inventing ways of killing each other. I cannot help but wonder what else we could have achieved with all that time, effort, ingenuity and money.

The issue we have is that successive Governments of the United Kingdom have supported and expanded the nuclear weapons programme at eye-watering cost. Why? When I sit in the House of Commons, I talk to many Members who support Trident. I can tell them that these weapons can kill tens of millions of people. But they know that. I can tell them that the watershed will be poisoned, crops will fail and many more will die in the most degrading ways from famine, pestilence and plague. But they know that. I can share stories of survivors, such as Setsuko Thurlow, who told me of people falling to the ground, bellies extended and bursting as they hit the ground, of people trying to carry their own eyes that had fallen out of their heads, and of people with their flesh falling off their bones as they died in agony.

I can also tell Members that WMD have not stopped wars across the globe from Vietnam to Afghanistan. But they know that. I can tell them that WMD are no protection from terrorism. But they know that. I can tell them that the £205 billion could be spent on health, education, housing, transport or even financing our conventional armed forces. But they know that, too.

The majority of supporters of WMD are just like me with one vital difference. They believe that WMD are a deterrent. They believe their existence has kept us safe. As those weapons have existed during a period in which we have avoided wars on the scale of the first and second world wars, I can see where they are coming from. If people believe that keeping their guard up is keeping them safe, then lowering their guard is a frightening thing to do. In this case, they are so frightened that they are prepared to carry out the greatest atrocity humankind has ever perpetrated, and have it done in their name. Well, not in my name. Not all countries believe that nuclear warfare is required. Maybe as many as nine countries feel the need to have nuclear weapons, out of 200.

[Dr Julian Lewis]

I make one point for the hon. Gentleman’s consideration—one could say exactly the same thing about poison gas, which was used in the first world war and not in the second. It was not used in the second because of fear of overwhelming retaliation. The British warned that we had those stocks and that we would retaliate not only on our own behalf but on behalf of our allies such as Russia. The question is, which keeps the peace?

[Ronnie Cowan]

We could say that about almost any weapon that we have managed to invent. The threat escalates because such weapons exist. We sit in this Chamber to debate all sorts of subjects, which we sometimes try to do in a fairly amicable manner. If that escalated and went beyond debate, it could turn to violence—but it does not, because we respect each other, we back off and we discuss it. We say to kids in the streets, “Don’t carry knives. If you are carrying one and I’m carrying one, someone will get stabbed.” We talk to those kids, saying, “Don’t carry those weapons,” yet here in this place our attitude towards ending war is to escalate the weapons that people can carry.
