Not every lebanese in israel is a traitor. first the lebanese government didn't give them the opportunity to come back and even if they did their houses their cars were burnt and many were taken to jails.
There are the people who fought against lebanese and killed lebanese citizens in south lebanon who should not be allowed to come back and if they do they should be taken to trail.
As for the families there's no reason they stay in israel they are lebanese like everyone and it's their full right to come back to lebanon today before tomorrow. i do have internet lebanese friends who live in israel they oppose the israel acts in lebanon but they're not allowed to come back because they're seen as a traitor. what does a child have to do?
besides there are reasons that pushed those people to go to israel don't ever think that people just like to go to isral for the sake of staying there.
check their website, those people want to come back to lebanon badly and i will be the first one to go to street if it's necessary because i don't accept that any lebanese who did nothing against his country to be exiled.
Note that the Lebanese southern army was being paid by the lebanese army till year 2000 (during the syrian occupation) it seems there's something fishy here.
