Both antagonists in the cold
war agree that international
control would have to back up
disarmament pacts, the Presi-
dent said.
Therefore, he continued,
"Plans for international con-
troll should be in instant readi-
ness. Why should we not at
once put our technicians to
work to study together and adj
wise as to what specific control
measures are necessary II there
Is to be a dependable and
agreed disarmament"
Technical Study Urged
Secretary Dulles called this
proposal for immediate tech
nical studies the heart of the
Presidents letter.
Noting that Mr.. Khrushchev
has talked about international
supervision, Mr.. Dulles said the
United States does not know
whether Russia's ideas are
along the same lines as ours.
While principles are debated.
he said, 1t would be useful to
get started at the other end
of the problem - technical
problems.
A group headed by DR.. James
r. Killian. jr.. the Presidents
science adviser. has concluded,
Mr.. Dulles said, that a complex
inspection system could elm
mate most Of the risk Of sur
reptitious nuclear explosions.
Controls could be refined to
the point where evasion Of q
ban on nuclear tests or pro-
duction probably would be de-
tected, Mr.. Dulles said. This
high degree of probability
would serve almost as well as
a foolproof system. he added.
because no country would be
likely to risk detection.
Need Complex System
Adequate supervision, Mr..
Dulles said, would require a
complex system with a very
considerable degree of inspec-
ton within the territories Of
Russia the United States and
other nuclear, powers. Inspec-
ton teams would have to be
given great mobility to check
suspicious activities. he said.
One problem. he said. would
be to determine whether an ex-
plosion was for a legitimate
civil purpose. or really masked
military test.
Even If the Soviets announce
O halt to nuclear weapons pro-
duction, as rumored. it would
be primarily propaganda with
out adequate controls, Mr..
Dulles said.
Detection of nuclear produc-
ton is also feasible, the Secre-
tary declared.
Mr.. Dulles said the United
States has not abandoned its
position that suspension Of nu-
clear tests and production
should be only one aspect Of
disarmament. But he said ne
gotiations should get started
with technical studies on the
nuclear phase.
Text Of Letter
The text Of the Presidents
letter follows:
II have your communication
of April 4 repeating. in sub
stance, the already widely pub
licized statement of the Soviet
government with reference to
the suspension Of nuclear test
ing.
'It seems peculiar that the
Soviet Union, having just con-
cluded a series Of tests Of un-
precedented intensity. should
now, in bold headlines, say that
it will not test again, but add.
In small type. that it may test
again If the United States car
ries out its already long an
nounced and now imminent
series Of tests.
The timing, wording, and
manner Of the Soviet declara-
ton cannot but raise questions
as to its real significance.
The position Of the United
States on this matter Of test
ing is well known. For several
years We have been seeking a
dependable ending to the &C
