Robert Worth: Israel and US troops invaded Lebanon to keep "peace"

Here is what he said: "The group is bent on expelling Israel and the Western troops who try to keep peace amid rising violence after Israel’s 1982 invasion."  Now, he could be referring only to Western troops and not to Israeli occupation troops, but still: US troops were in Lebanon to prop up the right-wing murderous regime of Amin Gemayyel.  In fact, the period of American "peace keeping" was one of the most bloody in the history of the civil war.
