The very first sentance of Slezkine's introduction is: "The Modern Age is the Jewish Age, and the twentieeth century, in particular, ins the Jewish Century. Modernization is about everyone becoming <b>urban</b>, mobile, literate, articulate, intellectually intricate, physically fastidious, and occupationally flexible". OK, he doesn't say "liberal" or "progressive" explicitly, but the connection seems clear, at least in the context of modern US politics. Nobody is going to associate George Bush with the articulate and intellectually intricate. Of course not all Jews everywhere are liberal/progressive, life is more complicated than that.
