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 conclu-
sion of their week-long con-
ference.

In the agreement, the iia
leaders promised that the,
United States and the Soviet
Union ‘‘will act in such a
manner as to prevent the
development of situations capa-|
ble of causing a dangerous
exacerbation of their relations,
as to avoid military confronta-
tions, and to exclude the)
outbreak of nuclear war be-
tween 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.”
Briefs Leaders

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

Kissinger said the intent of the
doctrine was “to prevent the
outbreak of nuclear war.”’

leaders to hold a third summit
conference in aS many years

peaceful uses of nuclear ener-
gy.
