Here at last is a photograph of Lev Leviev, the Israeli diamond merchant who is funding West Bank settlements. Harvey Weinstein of Miramax is having a party on December 4 at Leviev's Madison Avenue boite. Weinstein apparently has an online group of friends called "A Small World." Presumably self-congratulatory and not Dubai-based. One day they will describe this gilded age in history books and kids won't believe it. Especially when they describe the corruption and hypocrisy, the star treatment for a man who is destroying the two-state solution, when supposedly it's our government's policy. Adalah-NY will be picketing the party, trying to crash it. Starting at 6:15 on Madison Avenue at 62d.
