Silvio vs. Ehud

This one is for fans of The Sopranos and Israeli politics. [Warning: spoiler if you haven't watched up to episode 3 of the current season.]

P.S. Does anyone have a clue what they had in mind setting up the scene between the evangelical pastor and Tony's friend Hesh in the latest episode -- and more specifically, what did Hesh mean when he said "you just wait" after his wife says "evangelicals are great friends of Israel."
