Yes, that's right – Chabad's very own oiigarch, diamond and property magnate Lev Leviev is the richest man in Israel. Leviev owns Aftrica-Israel Corporation, and his net worth is said to be more than 6 billion dollars. Leviev – a native of the Former Soviet Union – funds much of Chabad's activities there.
But I do not think it is altruism alone that prompts Leviev's largesse. Leviev uses those donations to get certain things from both Chabad and Valdimir Putin, in particular, acess to ceertain natural resources Leviev trades in.
I don't track Leviev closely, so I may be wrong here, but it seems to me that a man, an Israeli, with 6 billion dollars might have the money to significantly help poor people in Israel. Yet I don't see his name attached to much giving there, and no real dent has been made in the poverty that plagues so many Israelis. Might this be because Israel does not have any diamonds to mine?
