Benjamin Netanyahu Thursday said he resigned as Israel's United Nations ambassador to protest Secretary of State George P. Shultz's meeting with two Arab-Americans linked to the PLO. "The meeting raises a larger question of the value of American commitments to us when we have made huge concessions to obtain these guarantees," Netanyahu said, referring to a 1975 American pledge not to meet with PLO members. Netanyahu's resignation was the strongest message yet from Israel regarding its displeasure over Shultz's meeting with two members of the PLO's self-declared legislative body.
