Why, Why, Why?

Fiorella is very upset about the callous murder of those three schoolboys coming home from religious school in Israel.  It was a heartless, deliberate provocation, and Fio's first reaction is DRONE PALESTINE TO CINDERS--which very well may happen because one of the boys was an American citizen.

But why, why, why?  Why this obsession with death and destruction?  Why not live in peace with Israel?  Why not live by the law instead of the sword?  And don't tell Fiorella it's because of Islam. That's just a excuse, like when Christians killed Muslims in Bosnia, and when Catholics and Protestants had at it in Ireland.

Why does anyone anywhere want to behave like this?
