CAMBRIDGE, Mass., Nov. 5 —More than 350 scholars have signed a statement urging President Nixon to withdraw United States support from Pakistan until there is a peaceful settlement of the India‐Pakistan crisis.

Schwartz of Harvard and Myron Weiner and Harold R. Isaacs of Massachusetts Institute of Technology.
