Aruri was Chancellor Professor (Emeritus) of Political Science, having served on the faculty of the University of Massachusetts-Dartmouth from 1965-1998.

Aruri’s papers have been preserved and are on display at the Claire T. Carney Library Archives and Special Collections at UMASS-Dartmouth.

[citation needed] Aruri was elected to three consecutive terms as a member of the board of directors of Amnesty International, USA (1984-1990).

He was a participant in the drafting of the Arab Covenant of Human Rights under the auspices of the International Institute of Higher Studies in Criminal Justice, in Siracusa, Italy in December 1986.

His book Dishonest Broker: the U.S. Role in Israel and Palestine, (South End Press 2003) has also been translated into Arabic, Spanish and Italian.

[citation needed] He was a harsh critic of the Oslo Peace Accords in what he suggested, at the time, amounted to a surrendering of the internationally recognized rights of the Palestinian people.

He has been especially vocal in his criticism of the PLO, and later the Palestine Authority (PA), for its complicity in a process that he has described as providing the framework and cover for further Israeli colonization of Palestinian land.
