Here is a Jewish fatwawawawa: "All civilians living in Gaza are collectively guilty for Kassam attacks on Sderot, former Sephardi chief rabbi Mordechai Eliyahu has written in a letter to Prime Minister Ehud Olmert. Eliyahu ruled that there was absolutely no moral prohibition against the indiscriminate killing of civilians during a potential massive military offensive on Gaza aimed at stopping the rocket launchings."
