Book excerpt: Palestinian and Israeli Public Opinion is based on a unique project: the Joint Israeli-Palestinian Poll (JIPP). Since 2000, Jacob Shamir and Khalil Shikaki have directed joint surveys among Israelis and Palestinians, providing a rare opportunity to examine public opinion on two sides of an intractable conflict. Adopting a two-level game theory approach, Shamir and Shikaki argue that public opinion is a multifaceted phenomenon and a critical player in international politics. They examine how the Israeli and Palestinian publics' assessments, expectations, mutual perceptions and misperceptions, and overt political action fed into domestic policy formation and international negotiations -- from the failure of the 2000 Camp David summit through the second Intifada and the elections of 2006. A discussion of the study's implications for policymaking and strategic framing of future peace agreements concludes this timely and informative book.
