In regard to reporting on the 2006 Israel-Lebanon conflict, Cook claimed that Human Rights Watch (HRW) made statements regarding the intentions of Israel and Hezbollah to target or to avoid targeting civilians which were not justified by the available evidence. A representative of HRW responded, defending the organisation's objectivity. Cook countered that he did not criticise the empirical aspects of HRW's research, only its interpretation of that research.
