Senior administration officials yesterday denied a report that the United States is considering a defense policy that would concede the loss one-third of West Germany in the case of a Soviet invasion of Western Europe

The denials, in response to a report by syndicated columnists Rowland Evans and Robert Novak published yesterday in The Washington Post, came from the State Department, Defense Secretary Harold Brown White House press secretary jody powell and President Carter's national security adviser, Zbigniew Brzezinski.

Brown, testifying before a Senate Armed Services subcommittee, said U.S. policy still is to contain any Soviet attack near the German border.

"I do not advocate and will not support a policy which called for the United States to accept a loss or defeat in Europe, " Brown said.

Powell, answering questions at the White House, said that Presidential Review Memorandum 10--the subject of the column-proposes no change in policy that would accept the loss of territory in Europe. U.S. policy, he said, remains uchanged and includes the possible use of tactival and strategic nuclear weapons as well as conventional forces in defense of Europe.

PRM-10 is the adminstration's overall review of U.S. global strategy, including military strengths and force levels. It has not yet been presented to the President.

Evans and Novak reported what they described as a meeting of high level administration officials July 28 and 29 to discuss aspects of PRM-10. The thrust of the column was that the officials agreed with Brezeninski's contention that given the "current political environment" the adminstration could not expect to gain support to procure enough conventional forces to assure turning back a Soviet invasion.

In these circumstances, the columnist said Brzezinski argued, the United States should adopt a "stalemate strategy," in effect " falling back and leaving the Soviets to face the political consequences (such as adverse world opinion) of their aggression." But under no circumstances, Brzezinski was reported to have said, should the United States publicly acknowledge any such change in its strategy, since this would cause an uproar in Western Europe, according to the columnists.

The syndicated column contained lengthy quotations attributed to Brzezinski which Evans and Novak said came from the verbatim notes of one of the participants in the meeting.

The White House did not directly deny that Brzezinski made the statements attributed to him. However, Jerrold Schecter, Brzezinski's press spokesman, said the statements in the column were "partial, inaccurate and deal only with one aspect of the over all defense strategy that might be applied in the event of an attack on Western Europe."

Schecter declined to elaborate on where the statements attributed to brzezinski were inaccurate.

Powell described the Evans and Novak report as another " in a series of the 'Oh, my God, they're caving into the Commies' columns" by the two writers, who are known for their hardline stance on defense issues.

Powell conceded that discussions of PRM-10 have included reviews of "political options" open to hit United States in the event of Soviet invasion, he said, "would be other than words."

Asked whether the administration believes the United States and its NATO allies currently have the strength to regain any territory initially lost to an invasion, Powell, after hesitating, replied:

"Yes we do ... It is our policy to regain any territory and it is our belief at this time that we can do that. However, it is important for NATO to take certain steps to maintain that ability." 0581tts ad 5 react-n golightly.

Carter reaffirmed U.S support of the alliance and simultaneously warned that unless there is an early agreement for mutual and balanced force reductions NATO must be beefed up."The collective deterrent strength of our alliance is effective," the president said." But it will only remain so if we work to improve it. The United States is prepared to make a major effort to this end...."
