William A. Rusher, publisher of the National Review, last night said that the shift of the balance of power in the United Nations to the Afro-Asian bloc was transformed it into a possible "instrumentality of measureless disaster for the free world."

The increased importance of the General Assembly, where this bloc can assert its full strength, Rusher said, has resulted in the "tragic and insane" spectacle of United States-financed troops opposing the pro-Western regime of Molshe Tshombe in Katanga Province in the Congo.

Calls for Re-Examination

United States reaction to this situation, Rusher, founder and first president of the Harvard Young Republicans, declared, should be a complete re-examination of its relation to the U.N. This appraisal must be based on recognition of involvement in a "cold war with mortal stakes." That is, we must follow the course profitable to our own national interests, and not become, like the Secretary-General, a "political slave of the Afro-Asian bloc."

Addressed YAF

Rusher spoke at the organizational meeting of the Harvard-Radcliffe Young Americans For Freedom, and was co-sponsored by the Law School and College Young Republican clubs. YAF is a conservative student organization founded by William A. Buckley, Jr. editor of The National Review.

As for the Kennedy and Eisenhower administrations, he characterized their leadership as "slothful, indifferent, and ignorant" but added "if we cannot see further, and act more wisely than we are now, it will not long matter how partisan we are."
