Strategic Defence and Security Review

As part of the coalition agreement, we agreed that we would have a value-for-money study to examine the costs of the programme and see where we could achieve better value within it. That is the process that is now ongoing. The Foreign Secretary has set out the new Government's distinctive British foreign policy, which has at its heart the pursuit and defence of UK interests and a recognition that our prosperity and security is bound up with that of others. That will require the enhancement of diplomatic relations with key partners, using Britain's unique network of friendships, bonds and alliances and working bilaterally as well as multilaterally. That does not mean that we must be able to do all things at all times. We will need to be smarter about when and how we deploy power, which tasks we can undertake in alliance with others, and what capabilities we will need as a result. That must be based on a hard-headed assessment of the current security environment and the growing threats to peace and stability. We live in a period in which direct military threats to UK territory are low, but in which the wider risks to our interests and way of life are growing. Over the coming decades, we could face weak or failing states creating new focal points for exportable Islamist terrorism that threatens our citizens and our allies, as we have seen in Yemen and Somalia. We could also face a nuclear-capable or nuclear-armed Iran destabilising Shi'a-Sunni and Arab-Persian fault lines, as well as those with Israel and the rest of the world. That could create an uncontrollable cycle of nuclear proliferation and, at worst, the erosion of the post-Hiroshima taboo against nuclear use by both Governments and terrorists. Elsewhere, we could see the emergence of old or new regional powers and the return of state-versus-state competition and confrontation. More immediately, competition for energy and other resources, including fresh water, could take on a military nature. It is conceivable that we will negotiate the next half century without confronting any of those risks—I certainly hope so—but it is equally possible that the UK could face security policy decisions relating to any or all such risks during the course of the next Parliament. That is the reality of the world in which we live, and we must break away from the recent habit of planning for the best-case scenario and then hoping the worst never happens. Unlike what happened during the cold war, we cannot be confident about how and how quickly such trends may evolve. I shall therefore conduct a thorough stocktake of our contingency plans in the months ahead. Of course, responding to such events would not be for Britain alone. Britain's relationship with the United States will remain critical for our national security; it is the UK's most important and prized strategic relationship.
