I am sorry, I will not give way, because too many others want to speak.
Above all, the policy is backed by the public. For that policy to be overturned, four thresholds have to be met. The first is that there must be a huge improvement in international relations. That has quite clearly not happened—things have deteriorated. Russia’s lowering of the threshold for the use of nuclear weapons, its activities in Ukraine, the situation in North Korea and the ability of terrorists to take over a country and possibly acquire nuclear technology mean that the world is much more dangerous.
The second threshold is that there must a compelling change of technology that would render nuclear submarines irrelevant. That has not happened. The third is a financial capacity that renders us unable to build them. That has not happened. The last is overwhelming evidence of public support shifting against the deterrent. That clearly has not happened.
