I believe that the whole issue of nuclear weapons will be increasingly important over the next 12 months and the period thereafter, partly because the First Foreign Policy Crisis with which President Obama will have to deal will be the question of nuclear weapons in Iran - and how he deals with that will also be influenced by what is happening on the wider nuclear weapons front - but also because I believe the time has come for major consideration of where the world is going with regard to the overall question of nuclear weapons.
