Would i be wrong to assume the most powerful Jewish crime bosses are those in Israel?
Big Fish/Small Pond as opposed to the viceversa Jewish gangsters operating in the US or elsewhere? I could be wrong, but it seems likely.

I know the Abergil Crime Family is powerful but has faced some kinda recent arrest's,
they supposedly have many bitter rivals who would very likely be on top now in lieu (of the arrest's)?
Hm. Im going to look into this.

Cool thread.

Wait a minute, isnt Semion Mogelevich a Jew? If so, then that guy. Most powerful that is.
