Israel (now broader Mid East discussion)

I don't think a glib, one-sided, and I would say dangerously misleading summation of the history of Lebanon is helpful.

For anyone interested in the background, I'd suggest starting here: https://en.wikipedia.org/wiki/Lebanese_Civil_War
While you may say its glib and one-sided, there is a lot more truth in her statement than there are omissions and falsehoods. Lebanon was a vibrant, multicultural society with a great economy until the PLO started to use Southern Lebanon as a staging ground for attacks on Israel. Any differences between the Maronite Christian population and moderate Islamic parties could have been settled peacefully without Arafat et. al. fanning the flames of hatred against Israel (and by association, the Christian population).
