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 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 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. Kissiner 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 at-
mosphere, 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 af-
ternoon flight to the Western
White House, Brezhnev
arranged to meet with 40
American businessmen to sell
them on expanded trade with
Russia.
