It is not for me to offer a lesson in the development of grand strategy, but in my training it was always all about ends, ways and means. We are attempting to establish the ends: what are we seeking to do? Clearly we seek to counter the threats that the UK faces. As to means, effectively people always focus on the capabilities that we have. That has been one of the challenges that we have faced in the wider debate, where
individual capabilities have been plucked out that hon. Members feel must be saved at all costs, without their necessarily looking at the wider context of how the means and capabilities fit together. Equally, part of the capability is the finance—the ability to buy it. Means therefore include both physical capability and money. Ways are how we use those means. The piece of work in question will grow on the NSCR, and as it continues, clearly, if factors emerge and investment in certain capabilities is needed, that will be a negotiation with the Treasury.
