Israel attacked Iraq (Operation Opera in 1981) and Syria (Operation Orchard in 2007) in order to prevent or forcefully disrupt their nuclear proliferation efforts. Currently, concern about Iran’s nuclear program has raised debate about the possibility of an Israeli pre-emptive attack. This thesis employs hypotheses from realist, constructivist and liberal theory to explain the use of force in counter-proliferation, using a strategy of within-case and across-case analysis of both prior attacks. I locate determining conditions that led Israel to use force in counter proliferation. The hypotheses explore conditions such as uncertainty about state identity, the perception of threat, the risk of shift in regional power balance, prior military hostility, hostile public statements made by state leaders, undeterrability and the domestic support of state leaders. Most of these conditions are present in the current case of Iran, when considering the possibility of a pre-emptive Israeli attack. If Iran’s military support to Hezbollah is interpreted as indirect military hostility, all the conditions for an Israeli pre-emptive attack would be present, when considering the conditions leading to the previous two Israeli attacks in counter proliferation. The analysis suggests there is a high chance that this will cause Israel to use pre-emptive force in order to destroy Iran’s nuclear facilities, as the “Begin Doctrine”, on which Israel’s security policy is based, will not accept such high security risks.Show less
