My Lords, happily we have not seen the use of these appalling weapons between those two countries. But recent tensions speak for themselves. Tensions between India and Pakistan make progress on a non-proliferation agenda all the more important, not just for the safety of south Asia but for the whole world. So the noble Lord, Lord Renton, is right; it is enormously important that we continue to press both countries to engage as soon as possible in dialogue on nuclear confidence-building measures. It is also very important that we encourage both countries to sign up to the non-proliferation treaty. We want to see them signed up as non-nuclear weapons states. That is an enormously important aspect of what we are encouraging them to do.
