 Basically, as you mentioned, the PLO made its headquarters in Lebanon in the 1970s. And so they were using South Lebanon, not just them, but all their Lebanese allies as well, used Lebanon as a way in which to kind of continue what they call the Palestinian revolution and to fight against the Israelis. So the Israelis would use that as an excuse to attack Lebanon, to hit Lebanese areas, Palestinian and Lebanese areas. So that was happening in 1978.
