The case for the retention of the UK's independent nuclear deterrent
The Defence Secretary set out the case for the retention of the UK's independent nuclear deterrent at Policy Exchange today

Thank you John.
It바카라 사이트s always a pleasure to speak at Policy Exchange.
Policy Exchange has led the public policy debate over the past 14 years on issues as far apart as housing and the impact of lawfare on our Armed Forces.
So I바카라 사이트m delighted to launch the new National Security Unit here today.
I바카라 사이트m pleased to see Policy Exchange going global. I know - under John Bew바카라 사이트s direction - you바카라 사이트ll bring your trademark clarity to the broader issues of national security.
At the moment all our thoughts today must of course be with our friends in Brussels.
The Strategic Defence and Security Review identified terrorism as one of the greatest challenges we face and it set out plans to tackle it.
Today, however, I want to focus on another important national security issue: the case for our independent nuclear deterrent.
DEFENCE AND DETERRENCE
Defence is the first duty of any 바카라 사이트.
As our SDSR said바카라 사이트and I quote바카라 사이트: 바카라 사이트Defence and protection start with deterrence, which has long been, and remains, at the heart of the UK바카라 사이트s national security policy바카라 사이트.
Deterrence means convincing any potential aggressor that the benefits of an attack are far outweighed by its consequences.
Deterrence draws upon the full spectrum of our capabilities바카라 사이트 diplomacy, economic policy, law enforcement, offensive cyber, covert means바카라 사이트and, of course, our Armed Forces.
Which is why the most fundamental role of the Armed Forces is not to fight wars, but 바카라 사이트 through their very existence 바카라 사이트 to deter, and thus to prevent war.
For no part of our Armed Forces is that more true than our nuclear capability. If nuclear weapons are fired, they have failed. But they are used every day: to deter.
This 바카라 사이트 was elected on a manifesto that included a commitment to build four new ballistic missile submarines 바카라 사이트 replacing the Vanguard submarines that come out of service from the early 2030s.
And we바카라 사이트ve committed to a debate and vote this year so that Parliament can endorse that decision. So now is the right time to set out why we should retain our nuclear deterrent.
There are three reasons.
Because we are realistic about the world we live in.
Because we take our responsibilities to the British people and to our Allies seriously.
And because that means that nuclear weapons are relevant now and are going to be relevant for the foreseeable future.
Let me take each in turn.
1. REALISM
First, it바카라 사이트s about realism.
Some characterise this debate as one of extremes. Between those who want to disarm and those who never will disarm.
Let me reject that artificiality. We all agree on the destructive power of nuclear weapons, and that we must do everything to ensure they will never be used.
We also have a shared ambition to see a world where nuclear weapons states feel able to relinquish them.
Where we really differ is how best to achieve this.
On the one hand are those idealists who believe that unilateral disarmament will make us safer바카라 사이트
바카라 사이트on the other are those of us who recognise that the real world threats to the United Kingdom are growing not diminishing.
So we must be realistic about the world in which we live.
The Labour 바카라 사이트바카라 사이트s 2006 White Paper on the future of the deterrent identified risks to the UK from major nuclear armed states from emerging nuclear states, and state sponsored terrorism.
Those risks have not gone away.
Indeed, nine years on, our own SDSR judged that the United Kingdom is facing challenges that are growing in scale, diversity, complexity and in concurrency.
Nor has the nuclear threat gone away. The SDSR recognised, and I quote, 바카라 사이트continuing risk of further proliferation of nuclear weapons바카라 사이트 and concluding that we could not 바카라 사이트relax our guard바카라 사이트 or rule out further shifts which would put us under grave threat바카라 사이트.
And Russian behaviour is a case in point here.
Russia has become more aggressive, more authoritarian and more nationalist. Its illegal annexation of Crimea and support of Ukrainian separatists through the use of deniable, hybrid tactics and media manipulation have shown its willingness to undermine the rules based international system in order to promote and secure its own perceived interests.
Russia is upgrading its nuclear forces; and Russia is threatening to base nuclear forces in Kaliningrad and in the Crimea.
The last two years have seen a worrying increase in both official Russian rhetoric about the use of nuclear weapons and the frequency of snap nuclear exercises.
And we should take heed of those developments.
North Korea is another worrying case study. North Korea is the only nation to have tested nuclear weapons in the 21st century. It now claims to have withdrawn from the Nuclear Non-Proliferation Treaty. It바카라 사이트s developing long-range missiles, and continues to flaunt its new found nuclear capabilities.
Just as we must be realistic about the growing nuclear threats, we also have to acknowledge that our prospects of single-handedly convincing the world to abandon its nuclear arms바카라 사이트 are limited.
Now we are committed to creating the conditions for a world without nuclear weapons, in line with our obligations under the Nuclear Non-Proliferation Treaty.
And we have led the way on disarmament.
We바카라 사이트ve cut our nuclear stockpiles by over half since the height of the Cold War
Last year I reduced the number of deployed warheads on each submarine from 48 to 40 last year
And we have pledged to reduce further our stockpile of nuclear weapons to no more than 180 warheads by the mid-2020s.
Other nations have not followed suit.
There remain about 17,000 nuclear weapons in the world바카라 사이트 we have less than one per cent of them.
It is frankly naïve 바카라 사이트 even vainglorious 바카라 사이트 to imagine that the grand gesture of UK unilateral disarmament could change the calculations of nuclear states, or those seeking to acquire weapons.
Far more likely they would see it as weakness.
So the only way to create the global security conditions necessary for achieving nuclear disarmament is by working multilaterally바카라 사이트
by taking tangible steps towards a safer and more stable world
And by giving states with nuclear weapons the confidence they require to relinquish them.
Our recent efforts, working alongside other leading powers, secured a deal with Iran and showed what can be achieved.
But we should also be realistic about how long this will take.
As the great nuclear theorist and former MOD Permanent Secretary, Sir Michael Quinlan, once wrote:
바카라 사이트no safer system than deterrence is yet in view, and impatience would be a catastrophic guide in the search. To tear down바카라 사이트 he said바카라 사이트 바카라 사이트the present structure, imperfect but effective, before a better one is firmly within our grasp would be an immensely dangerous and irresponsible act.바카라 사이트
2. RESPONSIBILITY
That brings me to my second point. We have a political and moral responsibility to our people and our Allies.
No-one would claim the nuclear deterrent solves all of our national security requirements.
Terrorist threats are all too real 바카라 사이트 as we saw so tragically yesterday. But nuclear weapons were never intended to combat terrorism.
They are intended to deter the most extreme dangers our nation might face.
What바카라 사이트s more, our independent deterrent isn바카라 사이트t just key to our security; it contributes to our NATO allies바카라 사이트 security as well.
NATO is the cornerstone of our defence. It is first and foremost a defensive alliance. And it is also a nuclear alliance.
By maintaining our independent nuclear deterrent, alongside the US and France, we provide NATO with three separate centres of decision-making.
That complicates the calculations of potential adversaries, and it prevents them threatening the UK, or our allies, with impunity.
Now some will ask why we possess nuclear weapons when other Allies such as Germany do without them.
But we can바카라 사이트t rewrite history. We were one of the original nuclear powers. Others were not.
And many of those Allies signed the Non-Proliferation Treaty in the late 1960s in the knowledge they were covered by NATO바카라 사이트s nuclear umbrella, including the United Kingdom deterrent.
It would not be the action of a strong and valued ally to withdraw that protection.
And how would the United States or France respond if we suddenly announced that we were abandoning our nuclear capabilities바카라 사이트
바카라 사이트yet will still expect them to pick up the tab and to put their cities at risk to protect us in a nuclear crisis?
Without our nuclear contribution to NATO, could we guarantee that a potential adversary might not miscalculate the degree of United States commitment to the defence of Europe?
As one of the leading member of NATO we shouldn바카라 사이트t now think of outsourcing our commitments.
That would not make us safer and it would have no moral merit.
It would weaken us now and in the future.
It would undermine NATO.
And it would embolden our adversaries.
3. RELEVANCE
That brings me to my third point: the relevance.
Our independent nuclear deterrent is relevant not only for today but also for the foreseeable future.
The UK case does not rest on our assessment of threats that face us now바카라 사이트.
바카라 사이트but on our assessment of what the world could be like in the 2030s, 2040s, 2050s and beyond바카라 사이트
And the truth is we don바카라 사이트t know.
No-one accurately predicted the end of the Cold War바카라 사이트or the coming of the Arab Spring, Russia바카라 사이트s annexation of Crimea, or the rise of Daesh.
Those who argue in favour of scrapping our nuclear deterrent unilaterally must be certain - absolutely certain - no extreme threats will emerge in the next 30 or 40 years to threaten our security and way of life.
And they can바카라 사이트t be so certain.
That is why successive 바카라 사이트s for over sixty years have concluded that this country should retain its nuclear weapons.
Now the UK government last formally presented the case for the future of the UK바카라 사이트s Nuclear Deterrent to Parliament in 2006.
Launching that White Paper Tony Blair, said 바카라 사이트an independent nuclear deterrent is an essential part of our insurance against the uncertainties and risks of the future.바카라 사이트
That was the right judgment then.
It바카라 사이트s the right judgment now.
Our nuclear deterrent has helped keep the peace between the major powers for decades.
Abandoning it, would undermine our security and that of our allies. It would not make us safer.
And once we gave those weapons, there would be no going back to them.
OBJECTIONS
That is the case for retaining a nuclear deterrent.
And I put it to you that it is hard to argue against the principle.
But, before concluding, let me finally address the main practical objections that people have raised.
First, the claim that there are cheaper and more effective ways of providing a similar effect to the Trident system.
There aren바카라 사이트t.
Successive studies have looked at this in detail바카라 사이트
바카라 사이트 under Labour Ministers in 2006바카라 사이트
바카라 사이트and more recently under the Conservative and Liberal Democrat Coalition in 2013.
They reached the same conclusion.
A minimum, credible, assured and independent deterrent requires nuclear submarines with ballistic missiles.
Other options were considered.
The Trident Alternatives Review in 2013 assessed what ships, aircraft, submarines and silos could deliver nuclear weapons; and which missiles, bombs or nuclear warheads were most appropriate.
It found that submarines were less vulnerable to attack than silos or aircraft.
They can maintain a continuous posture in a way that aircraft and land-based alternatives cannot.
It made clear that alternative delivery systems, such as cruise missiles, wouldn바카라 사이트t have the same range as the Trident missile 바카라 사이트 reducing the reach and capability of our deterrent.
Only the current submarine-based, Trident missile system offered the resilience but also the cost-effectiveness that successive UK 바카라 사이트s sought. The second objection is that submarines will somehow become obsolete, through technological developments such as unmanned underwater vehicles or cyber threats.
The ocean is a vast, complex and challenging environment in which to conduct large scale anti-submarine warfare.
Our confidence that submarines will not be rendered obsolete by technology is partly based on classified analysis, but also on some obvious facts.
Operating quietly for long periods in the ocean is highly demanding. It requires endurance, a powerful energy source, resilience from high pressure and corrosion, and stealth.
The ability to track submarines and then communicate their position brings with it many significant challenges.
Now we dedicate considerable resource to assessing these emerging capabilities. And we judge that there is no inherent reason, for the foreseeable future, to believe that unmanned submarines will be substantially more difficult to counter, than manned submarines.
As for cyber-attack, while deployed, submarines operate in isolation. It바카라 사이트s hard to think of a system less susceptible to cyber-attack.
And it바카라 사이트s also worth asking, if nuclear submarines were redundant, or going to be redundant, why would the United States, China, Russia and France all be spending tens of billions of dollars on their own submarine based ballistic missile systems?
As practical as these objections appear, they are in fact simply the latest in a litany of arguments employed to justify an anti-nuclear position.
COST
The third practical objection is cost.
Now we must remember that security underpins all the 바카라 사이트바카라 사이트s priorities.
With the fifth biggest defence budget in the world바카라 사이트backed up by our commitment to invest 2 per cent of GDP in defence바카라 사이트 we can afford conventional and nuclear capabilities.
Our estimate is that four new submarines will cost £31 billion to build. We바카라 사이트ve also set a contingency of £10 billion on top of that.
But the maximum acquisition cost will be spread over 35 years, which works out as an insurance premium of 0.2% per year of total 바카라 사이트 spending.
Twenty pence in every £100 pounds the 바카라 사이트 spends바카라 사이트for a system that will provide a capability through to the 2050s and beyond.
I believe that that is a price worth paying.
CONCLUSION
So let me say in conclusion바카라 사이트before nuclear weapons, major powers embarked on two of the most destructive wars imaginable.
Many millions died, millions more suffered.
Yet, for all the conventional conflicts since, and there have been many of them, there hasn바카라 사이트t been major conflict between nuclear armed states. The devastating possibilities of nuclear war have helped maintain strategic stability.
And our independent UK nuclear deterrent has played its part.
Those who still oppose it must prove to us how relinquishing it would make us safer.
Now we should not accept nuclear deterrence as the last word in ensuring freedom from major war. Our commitment under our Non-Proliferation Treaty obligations is clear.
But to abandon our deterrent now would be an act of supreme irresponsibility.
In 2007 Parliament voted to maintain the minimum strategic nuclear deterrent beyond the life of the existing system.
Last year Parliament voted twice to retain our deterrent.
This year Parliament will have the opportunity to vote on the principle of Continuous At Sea Deterrence and our plans for Successor.
This is not a judgment about short term threats.
It is about the threats we may face over generations to come.
We should not gamble with our national security.
The United Kingdom바카라 사이트s independent nuclear deterrent remains right for our nation 바카라 사이트 for as long as the global security situation demands.
Thank you.
