Strategic Defence and Security Review

I am not quite sure how to follow that quotation, so I shall confine myself to saying how moving remarks those were. I have to confess that I had not intended to speak today, but Members will understand why, in the circumstances, I thought I should stress the importance that my party continues to attach to retaining and renewing the UK's independent nuclear deterrent. I say at the outset that the nuclear deterrent should primarily and ultimately be a matter of national and global security, not of employment. If we could genuinely be confident that the UK unilaterally disarming would make the world safer for future generations of UK citizens, and would make the almost unimaginable horror and destruction of nuclear war less likely, that should of course come ahead even of the thousands of jobs that renewing the deterrent would support in my constituency and the many thousands more that it would support across the country in the supply chain. However, my simple point is that unilaterally disarming would do no such thing. If we were to take the view that deciding now not to renew would make the UK safer, we would have to be able to make decisions about the world as we thought it would look in 30 or 40 years' time. We would also have to believe that the unilateral gesture would pave the way for a change in behaviour by other regimes. On the latter point, disarming would show a fundamental misunderstanding of the motivation of other regimes and groups that seek, or may in the future seek, nuclear capability. They do that to increase their capacity for aggression, not primarily because they fear the UK's independent deterrent. On the former point, the pace of change has been so great in the past decade that we simply cannot possibly say with confidence that a deterrent will not be needed decades hence.
