While Hezbollah would launch its rockets with the goal of causing mass casualties to shock and demoralize the Israeli population, they would also likely attempt smaller but more devastating infrastructure assaults. High-value targets would include the industrial section of Haifa, whose sprawling petrochemical plants and oil refinery would be vulnerable to bombardment. The loss of the Haifa refinery, one of only two such installations in Israel, would threaten Israel's economic security. Hezbollah could also launch rockets against the city's port and Matam Park, a hub of Israeli high-tech development. Even minor damage could lead to serious disruptions in Israel's delicate economic framework. The vulnerability of the Israeli economy to a Hezbollah rocket attack was demonstrated by events in 1996 when the group fired over 500 Katyushas into northern Israel; Israeli officials placed the cost of the relatively minor two-week assault at approximately US$100 million.[11]
