Preparations for the Summit Conference 413



could settle on this basis this would loosen Khrushchev up on the other
points. He asked what other problems remained.
    Ambassador Wadsworth described the position on staffing which
was still a major issue. The Secretary said that we should not get into
discussion of this but should limit ourselves here to the fairly simple is-
sues. Mr. Lloyd agreed. He said that we should try initially to get agree-
ment on a quota of 20, on the length of the moratorium, and on a 4-4-3
Control Commission composition. The negotiators at Geneva would be
left to work out details. He then asked if there was anything likely to
come up in connection with the research program, noting that the Presi-
dent at his last press conference had spoken in terms of jointly con-
ducted nuclear tests. The Secretary explained the proposals that we had
sent to our delegation regarding the conduct of experiments in the re-
search program and how the terms of the Atomic Energy Act3 required
us to resort to the "black box" idea. This was a dilemma since
there was
also a problem in connection with yield measurements. Both sides will
need to know the yield of a particular device before results of experi-
mentation can be considered valid. If internal examination of the de-
vices used cannot be allowed, instrumentation will be required which
would be useful for purposes of weapons development.
    Ambassador Wadsworth said that his senior scientific adviser at
Geneva felt that the simplest solution to the problem would be for the
three parties to sit down and develop a new design, starting from
scratch. Mr. Farley noted that this would probably not solve the prob-
lems since technically a device became Restricted Data as soon as it was
conceived. Furthermore, there was the problem of accurate yield pre-
diction. Mr. O'Neill wondered what the position would be if British de-
vices which did not incorporate information received from the United
States were used. The Secretary said that he thought the law would not
apply in this case. Mr. O'Neill said that he did not think that the U.K.
classification system would require automatic declassification of de-
vices disclosed to the Soviets. The Secretary speculated that this might
be the solution to the problem we faced. Mr. Farley said that there were
other provisions of the law which might make it difficult to use even
these devices within the United States. The Secretary suggested that we
both look more closely into the possibilities and problems of this ap-
proach.
    Ambassador Wadsworth noted that a further unsolved problem re-
lated to high altitude tests, recalling the February 11 position4 that we
