Defence in the World

: My hon. Friend will recall that Rob McNamara made a similar plea when he spoke at the non-proliferation treaty review conference in New York recently. Will he acknowledge that one of the arguments used by the elements in Iran and North Korea that want to develop nuclear weapons is the fact that the five declared nuclear weapons states show no signs of disarming? Indeed, their position is quite the opposite because Britain and the United States show every sign of wanting to re-arm further. It becomes harder to argue against nuclear proliferation if we ourselves are expanding the nuclear horizons.
