SAN CLEMENTE, Calif., Nov. 25—The United States may ask the United Nations Security Council to consider the dispute between India and Pakistan, or support such a move by another country, the Western White House said today.

Ronald L. Ziegler, the White House press secretary, said that President Nixon had taken time out from celebration of the Thanksgiving holiday here to telephone Prime Minister Heath of Britain to discuss the fighting in South Asia and other matters.

Mr. Nixon was said to have reasserted to Mr. Heath the United States position that “the resort to military action” by India or Pakistan “would be hard for the American people to understand,”

Rules Out Joint Action

Mr. Ziegler said that joint action in the dispute by Washington and London was not contemplated, but he said in response to questions that the possibility of taking the matter before the Security Council was “under consideration” by the Nixon Administration.

Britain and the United States are permanent Security Council members, along with the Soviet Union, France and China. Western influence in India and Pakistan has been diminishing while the Russians have strengthened their ties with India and the Chinese their support for Pakistan.

Accordingly, it is thought that a concerted effort in the Security Council to bring the India‐Pakistan dispute under control might have more chance of success than diplomatic initiatives undertaken by the United States alone.

U.S. Assessing Situation

Mr. Ziegler said that no decision had been made on a request for Security Council consideration of the matter. The United States, he added, wants to continue for the moment its assessment of the situation. Secretary of State William P. Rogers summoned senior Indian and Pakistani diplomats to his office in Washington yesterday to appeal for a military disengagement.

The United States has stressed, and Mr. Ziegler did so again today, that it might be difficult for the American public to understand why the United States should give humanitarian aid to Pakistan and India should the fighting continue.

“There are so many human problems involved in the area that the solution seems to be self‐evident,” Mr. Ziegler said.

He added that, in the United States view, India and Pakistan were too beset with domestic problems to become embroiled in an external conflict.

The President spent about 30 minutes on the telephone this morning with Prime Minister Heath. Mr. Ziegler said that the President had discussed the agreement between Britain and Rhodesia on steps to return the former African colony to Commonwealth status. Rhodesia's white minority government declared itself independent of Britain in 1965.

According to Mr. Ziegler, it was also likely that Mr. Nixon and Mr. Heath discussed the possibility of a meeting before the President undertakes his trips to Peking and Moscow. The White ‘House announced yesterday that Mr. Nixon would consult with President. Pompidou of France in the Azores on Dec. 13 and 14 and strongly hinted that other meetings would be arranged with officials of major American allies to brief them on the forthcoming visits to China and the Soviet Union.
