After The New York Sun ran an editorial and two op-ed pieces taking Human Rights Watch to task for anti-Israel bias, the organization’s executive director, Kenneth Roth, has finally found it in himself to denounce Hezbollah for placing troops and weapons near Lebanese civilians. And to acknowledge, for the first time, that the use of ambulances by Palestinian groups to transport weapons or suicide bombers is “a clear humanitarian violation.” We’re tempted to congratulate Mr. Roth. Too bad it had to be wrung out of him.
