Messrs. Solarz and Buckley start from the assumption that whatever decisions we take vis-a-vis the Soviet Union--whether in terms of troop strength in Europe or in terms of arms control (currently on the table was President Reagan's Zero Option: that the Soviets dismantle their intermediate-range nuclear forces in Europe, in return for our not deploying the Pershing II and cruise missiles)--must be predicated on the need to protect ourselves and our allies. Mr. Barnet starts from the assumption that we are the problem, not the solution. And never the twain shall meet. RB: "I think the Soviet Union has maneuvered itself, largely with the help of this Administration, into a position where they appear to be readier to take the missiles out and to reverse the course and to negotiate than we." WFB: "You must be kidding."
