Ron Radosh has some thoughts on anti-Israeli Jews.
[Update late morning]
More thoughts, and good ones, from Noah Pollack:
The sad truth is that Peter Beinart isn’t any kind of trailblazer or whistleblower, and he most certainly has not earned himself any trouble by coming out as an Israel-basher. He is someone who has rather belatedly fallen completely and predictably into line with the demands his ideological compatriots make for orthodoxy when it comes to their increasingly passionate interest in assaulting Israel and championing the Palestinian cause. In Beinart’s work, we are not witnessing an act of courage but rather a spectacle of conformity.
I used to think that Beinart was smarter than that.
