WASHINGTON, Nov. 14--The United States and Britain brushed aside strong French protests today and ordered a token shipment of small arms sent to Tunisia in an effort to prevent the French colony from turning to Soviet arms suppliers.

The action, after hectic diplomatic activity in the Big Three capitals, threatened a major rift in the Atlanic Alliance at a time of critical new efforts to draw it closer together.

The new French government of Premier Felix Gaillard was threatened with possible overthrow in the French Assembly as a result of the move.

UN Asks Disarmament Talks

UNITED NATIONS, N.Y., Nov. 14--The United Nations called today for new talks to break the disarmament deadlock despite the Soviet Union's announcement it will refuse to take part in them.

The General Assembly approved a Wesern resolution asking for new negotiations in the five-nation U.N. disarmament subcommittee. Only the Soviet bloc opposed the resolution, making clear it has no intention of attending any more subcommittee meetings.

Security Council Budget Talk

WASHINGTON, Nov. 14--President Eisenhower and the National Security Council dug again today into the question of shaping the federal budget to the demands of space age defense.

Press Secretary James C. Hagerty said it was not possible at this time to expand on Eisenhower's statement last night at Oklahoma City about cutting down on nondefense spending to permit an increase on defense.
