There are no reports that 4000 people were killed in Lebanon over the last months by Israel, at all. You're really letting this Jew Derangement Syndrome get the better of you.
The only hostilities there have been have been between Hezbollah and other factions, not Christians. Lebanon has ordered Hezbollah to disarm. There are no Christians in Hezbollah and Hezbollah have caused more Christian deaths in Lebanon than Israel.
