Who are AJC, AIPAC and ADL that I should care what they say about anything. I do not know AJC, AIPAC and ADL, neither will I quietly accept Hagel.
The problem with these other (left-leaning) Jewish organizations isn't their support for Hagel, but rather their love for Obama, which is the underlying reason for acquiescing to the Hagel nomination.
If they had any integrity at all, they would have opposed Obama in last year's presidential campaign just like they should be opposing Hagel's nomination now.
Among American Jews abroad in Israel last year, 85% of the presidential vote went to Romney over Obama. There's a pretty valid reason for that, but apparently this bunch of Jewish organizations that Klein is criticizing doesn't get it.
