I agree with the hon. Gentleman's last point. That is precisely what has been happening in recent weeks, and what we hope will continue to happen in the months ahead. On SALT 2, we have repeatedly made it clear that the SALT agreements should be observed by both sides. We have also made it clear that the Soviet Union has a case to answer as regards possible breaches and that it should respond to legitimate United States anxieties about Soviet compliance. On zero-zero, it is clear that as we move, as I hope we shall, in the months ahead to long-term elimination of long-range weapons and constraints on short-range weapons, the disparities in conventional weapons and conventional manpower, which are much in favour of the Soviets at present, must be confronted at the same time, especially if central Europe is to become a safer place.
