More specifically, we'll consider the CIA's invocation (in the months and years after 9/11) of past Israeli practices in this area as a justification for American practices. In that context, you might click here for the landmark 1999 Israeli Supreme Court ruling that ruled out all torture (except for specific interrogation techniques that would be subsequently approved by the Knesset). And you can click here for one writer's reflections about the 1999 ruling.
You might be interested in clicking here for a 2011 from the Israeli human rights organization B'Tselem for a sense of how Israel has navigated some of these questions since 1999.
Finally, click here for an overview on the question of Jewish law and the treatment of prisoners.
As always, I welcome your questions and comments on this important and complex question.
