The Lebanese border continued to constitute the main threat to ongoing security. This period saw 2,400 attacks, with 41 killed and 181 injured IDF soldiers and 416 injured SLA soldiers. In particular, the first two years after the withdrawal were very difficult. However, the IDF built a defensive system which included the following components:
- Maintaining the key area of General Antoine Lahad’s enclave in the Jezine area as an intelligence base and source for initiated activities in the whole southern Lebanon area, in the north to the Lebanese mountains, in the west towards the coastal plain and in the east towards the Beka’a.
- Strengthening the SLA and turning it into an increasingly efficient fighting force specializing in field security activities and establishing an efficient intelligence element in the SLA.
- On-going operations of top infantry battalions in the framework of two regional brigades of the northern regional divisions. These operations’ included activity within Lebanese territory
- Maintaining an effective umbrella for the regional divisions, from the point of view of the quality of the personnel, artillery, identification systems and combat helicopters and by the availability of means for dealing with every event.
- Using the Air Force against targets across Lebanon which serve as infrastructure and bases for terrorists.
- Using the Air Force to gather continuous intelligence in Lebanon.
- Using the Navy to close the maritime border and continuously patrol opposite the ports, as well as organize activities along the coast, such as initiated operations from the sea against these targets.
- Activities to coordinate operations in Lebanon, utilizing various forces and events for the benefit of the IDF.
This system significantly increased the efficiency of the IDF during 1989-90 in defending northern Israel from terrorist attacks.
