There are no fireworks at this meeting of two old friends, but there is broad and deep discussion of the world and how Mr. Reagan may have changed it. WFB: "Conceivably, might there be USSR-American cooperation in developing SDI?" RR: "Well... I have told [Gorbachev] that I would advocate making that information open to the world ... in return for all of us destroying our nuclear weapons. But I said the reason for having it is- I used the example of World War I. I said all the nations of World War I met and outlawed poison gas, but we all kept our gats masks. I said, Who can say that down the way somewhere there won't be another Hitler, there won't be another madman that could use the knowledge of how to make weapons and blackmail the earth?"
