The highly controversial Disengagement Plan was discussed at the Israel Democracy Institute both before and after its implementation. 
 
Already in 2003, The IDI released a Policy Paper on The Political and Social Ramifications of Evacuating Settlements in Judea, Samaria and the Gaza Strip (translated and released in English in 2004). In 2004, Tamar Guttman wrote an article for the IDI entitled Discourse on Disengagement: Sensationalism in the Mainstream Press.
 
In April 2005, IDI Fellows went to Kedumim to meet with settlers to discuss and share views on the disengagement. Earlier that same day, Minister of Justice Tzipi Livni called upon the Israel Democracy Institute (IDI) to convene a panel of experts to discuss the current law on incitement to violence. 
 
In mid-June, The Media and Israeli Society was presented at the Roundtable where Senior Fellow Professor Asher Arian presented statistical information on how different sectors of Israeli society view the media in light of the pending disengagement plan. Later that month, at the IDI’s Annual Economic Conference, the Caesarea Conference, the first panel was dedicated to the economic implications of the disengagement plan.
 
Immediately following the implementation of the disengagement, the IDI hosted a discussion on how to carry on after the disengagement. IDI Fellows, Yesha Council members, Rabbis and key figures from the Left and the Right were there. Shortly after, the IDI released a Policy Paper entitled The Secret of its Strength: The Yesha Council and its Campaign Against the Security Fence and the Disengagement Plan (hebrew), by Anat Roth. This paper was later discussed in December, at an event open to the public which included two panels for the evening: one on the Yesha Council with regards to the disengagement, and one on lobbying in Israel and influence on the decision-making process.
 
And, yet, the big question still lingered: Did Israel Stand the Test of Democracy? The President of the Israel Democracy Institute and many of its senior fellows answered this crucial question.
 
In the fall of 2007, IDI researcher Yair Sheleg published a follow-up to his former Policy Paper on evacuating settlements. Read an interview with Yair Sheleg on the Occasion of his New Paper: The Political and Social Ramifications of Evacuating Settlements in Judea, Samaria, and the Gaza Strip: Disengagement 2005 as a Test Case.
