A fascinating reflective paper from an Israeli think tank, which aims to:
to examine the processes that led to the First Lebanon War, the role played by Lebanese domestic and foreign actors in the road to war, and the unique nature of the war. At the end of the paper I will attempt to provide a brief commentary on the aims, results, and lessons of the war from my own point of view.

It is a good easy read and I was struck by one passage (No. 21):
However, Israel’s political leadership learned the hard way that the military achievements in Lebanon, attained in what was essentially asymmetrical warfare in a theater rife with difficulties and problems, were difficult if not impossible to translate into sustainable political achievements. Indeed, looking at the results of the war in a thirty-year retrospective shows that Israel was unable to attain its strategic objectives.
Sounds like Afghanistan to me.

I have looked around SWC and cannot find a thread on the First Lebanon War, although there are several on later wars and related aspects.
