WASHINGTON AP — The United States
and the Soviet Union Thursday signed an
agreement of principles designed to
permanently limit nuclear weapons by the
end of 1974,

President Nixon and Communist leader
Leonid I. Brezhnev signed for their nations
at the White House. The agreement, the
outstanding accomplishment 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
inconsistent with the goa] of strengthening
peaceful relations.

The agreement is designed to spur
negotiators for both countries at
now-recessed talks in Geneva. Significant-
ly, the arms limitation envisioned by the
end of next year would include not only
numbers but the quality of the missiles

themselves.
Niewnan and Rrashnoeyu alen acraad that
 limitation on strategic offensive arms
must be subject to ‘adequate verifica-
tion.’’ 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 points of the compact
include: 1) controlling thermonuclear
fusion; 2) research on ‘fast breeder”
reactors which create more fuel than they
consume; 3) research on the fundamental
properties of physical matter.

A similar arms understanding between
Nixon and Brezhnev in 1971 produced,
when Nixon went to Moscow to see
Brezhnev last spring, an initial but limited
nuclear weapons agreement.
 Dr. Henry A. Kissinger, the President’s
national security adviser, told newsmen
that Nixon and Brezhnev are convinced an
expanded agreement by the end of 1974
would be ‘‘a major contribution in
reducing the danger of an outbreak of
nuclear war.”

He said they were agreeing now to seven
basic principles out of ‘sense of urgency.”’

The current SALT talks in Geneva have
become static and are recess. The new
understanding is designed to provide an
impetus for positive negotiations. Know
Know-
ledgeable observers estimate the second
pact would be ready by the end of 1974.
 
WASHINGTON (AP) — The
United States and the Soviet
Union Thursday signed an
agreement in principle to lim-
it 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 suc-
cess 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 Brézh-
nev 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 limi-
tation talks (SALT) in Gen-
eva.

For the first time, the two
nations committed themselves
in principle to actual reduc-
 tions of their nuclear weapon-
ry 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 ‘‘na-
tional technical means’ be
the system of verifying
whether Washington and Mos-
 cow were living up to a mis-
sile limitation.

Surveillance of multiple in-
dependently targeted  war-
heads MIRVS evidently would
be restricted mostly to obser-
vation by radar and spy sat-
ellite while in flight tests.

Henry A. Kissinger, the
President’s national security
adviser, briefing newsmen,
 said that “those MIRV agree-
ments that are not verifiable
by national technical means
would be difficult to recon-
cile”’ with the objective of re-
stricting complex nuclear of-
fensive weapons.

The two nations agreed in
another provision that efforts
