WASHINGTON (AP) — The
United States and the Soviet
Union Thursday signed an
agreement in principle to limit
and possibly reduce their
stockpiles of offensive nuclear
weapons by the end of 1974.

President Nixon and Soviet
Communist leader Leonid I
Brezhnev raised their cham-
pagne glasses in toasts to
success at the ceremony in the
White House East Room.

The agreement, the out-
standing accomplishment of
their week-long summit was
forged by Nixon and Brezhnev
earlier at Camp David, the
presidential retreat in the
mountains of Maryland. It is
 designed to spur negotiators for
the two countries at the
recessed strategic arms
limitation talks (SALT) in
Geneva’ *

For the first time, the two
nations committed themselves
in principle to actual reductions
of their nuclear weaponry as
well as to permanent
limitations. Also significantly,
the United States evidently is
bowing to Soviet objections to
on-site inspections.

One of the seven stated
principles provides that
“national technical means’’ be
the system of verifying whether
Washington and Moscow were
living up to a missile limitation.
 Surveillance of multiple
independently targeted
warheads (MIRVS) evidently
would be restricted mostly to
observation by radar and spy
satellite while in flight tests.

Henry A. Kissinger, the
President's national security
adviser, briefing newsmen,
said that ‘those MIRV
agreements that are not
verifiable by national technical
means would be difficult to
reconcile’’ with the objective of
restricting complex nuclear
offensive weapons.

The two nations agreed in
another provision that efforts
by one or the other to obtain a
nuclear advantage would be
 inconsistent with the goal of
strengthening peaceful
relations

The arms limitation en-
visioned by the end of next year
would include not only numbers
but the quality of the missiles.

Nixon and Brezhnev also
agreed that limitation on
strategic offensive arms must
be subject to ‘‘adequate
verification.’ 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
succeeds a series of two-year
agreements.

The major areas of the joint
arms effort include: (1) con
trolling thermonuclear fusion,
(2) research on ‘‘fast breeder”
reactors which create more
fuel than they consume; (3)
research on the fundamental
properties of physical matter

Nixon and Brezhnev flew
down by helicopter from the
Catoctin Mountains to sign the
historic document on the fourth
day of their summitry. A
similar arms understanding
between them in 1971 produced,
when Nixon went to Moscow to
see Brezhnev last spring, an
initial but limited nuclear
weapons agreement
