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 ‘‘im-
mediately enter into urgent consultations
with each other’’ should the risk 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 confrontations, 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 other party, and against other
countries, in circumstances which may en-
danger international 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.

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.

standing between Nixon and
Brezhnev in 1971 produced
