other summit talk in the So
viet Union next year.

WASHINGTON (AP) — The
United States and the Soviet
Union Thursday signed an
agreement of principles de
signed to permanently limit nu-
clear weapons by the end of
1974.

President Nixon and Commu-
nist leader Leonid I. Brezhnev
signed for their nations at the
White House. The agreement,
the outstanding accom-
plishment of their summit
talks, was cemented at the
President’s Camp David retreat
in the Maryland mountains.

The two nations agreed as a
matter of principle that efforts
by one or the other to obtain a
nuclear advantage would be in-
consistent with the goal of
strengthening peaceful _rela-
 The agreement is designed to
spur negotiators for both coun-
tries at now-recessed talks in
Geneva. Significantly, the arms
limitation envisioned by the end
of next year would include not
only numbers but the quality of
the missiles themselves.

Nixon and Brezhnev also
agreed that limitation on
strategic offensive arms must
be subject to ‘‘adequate veri-
fication."’ Both nations would
be permitted to modernize and
replace weapons only under
conditions to be agreed upon at
Geneva.

At the same time, Nixon and
Brezhnev signed a 10-year pact
to expand cooperation between
the two countries on peaceful
uses of atomic energy. It suc-
ceeds a_ series of two-year
agreements.

The major points of the com-
pact include: (1) controlling
thermonuclear fusion; (2) re
search on “fast breeder’ reac-
tors which create more fuel
 than they consume; (3) re
search on the _ fundamental
properties of physical matter.
A similar arms _ under-
standing between Nixon and
Brezhnev in 1971 produced
an initial but limited nuclear
weapons acreaamant
 
WASHINGTON (UPI) — President
Nixon and Soviet leader Leonid I.
Brezhnev pledged today to avoid
military confrontations and threats of
force that might lead to nuclear war
between their two nations,

In a policy declaration, the leaders of
the two nuclear superpowers agreed to
“immediately enter into urgent con-
sultations with each other” should the
Tisk of a nuclear conflict arise.

Nixon and Brezhnev signed the
agreement —-the eighth since the start
of their summit talks —in a ceremony in
the East Room of the White House a few
hours before their scheduled departure
aboard the presidential jetliner for San
 Clemente, Calif., for the conclusion of
their week-long conference.

. In the agreement, the two leaders
promised that the United States and the
Soviet Union “will act in such a manner
as to prevent the development of
situations capable of causing a
dangerous exacerbation of their
relations, as to avoid military con-
frontations, and to exclude the outbreak
of nuclear war between them and
between either of the parties and other
countries,"

The accord also calls for the
signatories to proceed from the premise
that each will refrain “from the threat
or use of force against the other party,-
 against the allies of the cther party, and
against other countries, in cir-
cumstances which may endanger in-
ternational peace and security,”

In advance of the signing, Nixon
briefed congressional leaders of both
parties on the declaration, which is a
statement of policy —not a treaty — and
therefore does not require Senate
ratification.

Presidential adviser Henry A.
Kissinger said the intent of the doctrine
was ‘to prevent the outbreak of nuclear
war.”

The decision of the two leaders to hold
a third summit conference in as many
years was announced at a lavish
banquet at the Soviet Embassy. In a
jovial atmosphere, Nixon and Brezhnev
dined and toasted each other after
signing pacts earlier in the day to speed
nuclear arms negotiations and
cooperate in research on peaceful uses
of nuclear energy.

Before they boarded the “Spirit of 76”
for a late afternoon flight to the Western
White House, Brezhnev arranged to
meet with 40 American businessmen to

sell them on expanded trade with
Russia.
