Since its establishment in the early 1980s, Hizbollah has viewed Israel as a bitter foe to be destroyed. With this mindset, it waged a stubborn military struggle against the presence of the Israeli military in Lebanon until Israel's withdrawal from the security zone in May 2000. As part of this campaign, Hizbollah gathered intelligence on the security forces operating in Lebanon. Analysis of Hizbollah's activities in those years suggests that the information was gathered primarily through lookouts; the goal was to become familiar with the routine operations of the Israeli forces in the region and improve the effectiveness of attacks on IDF outposts and the placement of booby traps along the roads.
