Avineri served as director of the Eshkol Research Institute (1971–1974), dean of Faculty of Social Sciences (1974–1976), director-general of the
Ministry of Foreign Affairs (1976–1977), and director of the Institute for European Studies at the Hebrew University (1997–2002). Avineri had numerous visiting appointments including
Yale University,
Wesleyan University,
Australian National University,
Cornell University,
University of California,
The Queen's College, Oxford,
Northwestern University,
Cardozo School of Law,
Oxford, and the
University of Toronto. He was a visiting scholar at the
Wilson Center, the Carnegie Endowment for International Peace,
Brookings Institution in Washington, DC, and at the Institute of World Economics and International Relations in Moscow. He was a recurring visiting professor at the Central European University, in Budapest. He was also a veteran board member of the
Israel Council on Foreign Relations. Avineri served as Director-General of Israel's Ministry of Foreign Affairs from 1975 to 1977. He also headed the Israeli delegation to the
UNESCO General Assembly, and in 1979 he was a member of the joint Egyptian-Israeli commission that negotiated the cultural and scientific agreement between the two countries. When the
Rabin government appointed Avineri to the post of director-general of the Foreign Ministry in 1975, it was harshly criticized by the
Likud opposition because of Avineri's support for negotiations with the
Palestine Liberation Organization (PLO). During his time at the Foreign Ministry, Avineri followed the official line of the Rabin government preferring the "
Jordanian Option" and participated in some of the meetings with
King Hussein. But in his writings, and internal Foreign Ministry memoranda, he tried to present the conflict with the Palestinians within a wider context of a conflict between two national movements, beyond the narrow ideological or security-oriented conventional Israeli discourse. At that time, some of the first unofficial meetings between Israeli peace activists and PLO officials also took place. These developments were curtailed by the Likud electoral victory in 1977, which also led to Avineri's resignation from the Foreign Ministry, but were resumed in the 1990s in the second government of Rabin and led to the
Oslo accords between Israel and the PLO. ==Honors and awards==
