I didn't see it.
But scripturally (I'm talking Torah/OT/NT/Bible, not talmud) wine symbolizes the processed fruits, in other words something like a spiritually-matured person . The grapes in the vineyard and olives on the olive tree and barley on the Judean hillside are raw fruit or produce. When the grapes are turned into wine, and the olives rendered into olive oil, and the barley beaten into fine flour, these types of produce represent completed or refined spiritual types.
I don't know if that's what Netanyahu would believe. I'm stating what some Christians believe.
