Several published reports indicate that top Israeli decisionmakers are seriously considering whether to order a military strike on Iran's nuclear facilities, and if so, when. Twice in Israel's history, it has conducted air strikes aimed at halting or delaying what Israeli policymakers believed to be efforts to acquire nuclear weapons by a Middle Eastern state-destroying Iraq's Osirak reactor in 1981 and a facility the Israelis identified as a reactor under construction in Syria in 2007. Today, Israeli officials generally view the prospect of a nuclear-armed Iran as an unacceptable threat to Israeli security-with some describing it as an existential threat. This report analyzes key factors that may influence Israeli political decisions relating to a possible strike on Iranian nuclear facilities. These include, but are not limited to, the views of and relationships among Israeli leaders; the views of the Israeli public; U.S., regional, and international stances and responses as perceived and anticipated by Israel; Israeli estimates of the potential effectiveness and risks of a possible strike; and responses Israeli leaders anticipate from Iran and Iranian-allied actors-including Hezbollah and Hamas-regionally and internationally.

This report and its appendixes provide background information on Hamas, or the Islamic Resistance Movement, and U.S. policy towards it. It also includes information and analysis on (1) the threats Hamas currently poses to U.S. interests, (2) how Hamas compares with other Middle East terrorist groups, (3) Hamas's ideology and policies (both generally and on discrete issues), (4) its leadership and organization, and (5) its sources of assistance. Finally, the report raises and discusses various legislative and oversight options related to foreign aid strategies, financial sanctions, and regional and international political approaches. In evaluating these options, Congress can assess how Hamas has emerged and adapted over time, and also scrutinize the track record of U.S., Israeli, and international policy to counter Hamas. Hamas is a Palestinian Islamist military and sociopolitical movement that grew out of the Muslim Brotherhood. The United States, Israel, the European Union, and Canada consider Hamas a terrorist organization because of (1) its violent resistance to what it deems Israeli occupation of historic Palestine (constituting present-day Israel, West Bank, and Gaza Strip), and (2) its rejection of the off-and-on peace process involving Israel and the Palestine Liberation Organization (PLO) since the early 1990s. Since Hamas's inception in 1987, it has maintained its primary base of political support and its military command in the Gaza Strip-a territory it has controlled since June 2007-while also having a significant presence in the West Bank. The movement's political leadership is currently headquartered in exile in Damascus, Syria. Hamas receives assistance and training from Iran, Syria, and the Lebanese Shiite militant group Hezbollah. Hamas is often discussed alongside other groups in the region that engage in militant and terrorist activities to achieve their ends, yet Hamas has confined its militancy to Israel and the Palestinian territories-distinguishing it from the broader aspirations expressed by Al Qaeda and its affiliates. The overarching U.S. goal regarding Hamas is to deter, transform, marginalize, or neutralize it so that it no longer presents a threat to Israel's security, to a peaceful and lasting resolution of the Israeli-Palestinian conflict, or to other U.S. interests-either in its own right or as a proxy of Iran or other actors. Various legislative and policy initiatives designed to accomplish this goal have at most achieved temporary or partial success. It is possible to conclude that U.S. and other international support for Israel and the Palestinian Authority/PLO dominated by Fatah (Hamas's main rival faction) has been counterproductive to some extent when comparing Hamas's domestic, regional, and international strength in the early 1990s-measured by factors such as popularity, military force, and leverage with other actors (including Israel and Fatah)-to its current strength. The Israeli-Egyptian closure regime in Gaza and various U.S. and international initiatives constrain and isolate Hamas to a point and may exacerbate its internal organizational tensions and tactical disagreements. Yet, the threats Hamas continues to pose to Israel, to prospects for a two-state solution and to the future of Palestinian democracy present considerable risks and difficult trade-offs for any U.S. policy decisions going forward.

The circumstances surrounding the collapse of the Camp David summit between U.S. president Bill Clinton, Israeli prime minister Ehud Barak and Palestinian Authority (PA) Chairman Yasser Arafat in July 2000 are still hotly debated by scholars and experts of the Israeli-Palestinian conflict. In pointing out the myriad of reasons for the breakdown, some have pointed to flaws in leaders' personalities and differences in negotiation styles; others have stressed the lack of sufficient preparations for the summit and the initial unbridgeable differences between the parties attending it. Most experts, however, agree that domestic considerations played a major role in the summit progression and eventual breakdown. This book highlights the attempts to salvage peace against the backdrop of intensifying violence during the Israeli-Palestinian Conflict and the role of domestic factors, particularly public opinion in determining the conduct of Israelis and Palestinians since the beginning of the second intifada. This book consists of public documents which have been located, gathered, combined, reformatted, and enhanced with a subject index, selectively edited and bound to provide easy access.
