There is widespread belief throughout the free world that, but for American nuclear superiority, Europe would already have been reduced to satellite status and the Iron Curtain would have reached the Atlantic and the Channel. Unless a trustworthy and universal agreement upon disarmament, conventional and nuclear alike, can be reached and an effective system of inspection is established and is actually working, there is only one sane policy for the free world in the next few years. That is what we call defence through deterrents. This we have already adopted and proclaimed. These deterrents may at any time become the parents of disarmament, provided that they deter. To make our contribution to the deterrent we must ourselves possess the most up-to-date nuclear weapons, and the means of delivering them.
