"Your letter received this morning raises a grave issue. You will remember that I only undertook to do the recordings on condition that I was allowed to say my say about nuclear weapons and nuclear war and defence policy. If your superiors insist on cutting part of what I said on these subjects, they are certain to cut the most vital parts and arrange that my whole position shall seem inept. If this is done, it will mean that two days of my time and a very great deal of my energy have been fraudulently wasted. Since the time that remains to me is probably limited, this is a grave matter. I must ask you therefore to mention that, if what I said on the above subjects is at all seriously cut, I shall repudiate the whole recordings and forbid their being used."
