Considering that 1) They're a militia within a state that clashes and killed Lebanese soldiers before and 2) they never acted in self defense, I fail to see the points in your argument. Their constant attacks on the north of the country, with the jewel being Child killer Samir Kuntar, and their border attacks including the one that started the 2006 war (on which Nasrallah later apologized) leave your argument basically invalid. "Treat others with dignity" The chicken or the egg? Who invaded Israel from multiple borders in several wars since it's re-creation?
