What do you do when you are immersed from childhood in pre-medieval law which distinguishes between killing a Jew and killing a Gentile? While killing anybody is forbidden by Halakha, the murderer is punished by execution if he killed a Jew, but is only "punished by God" if he killed a Noahide (e.g., a Muslim). Today you have rabbinic opinions that allow killing of Arabs, even innocents, that endanger Jewish control of the Land. They simply compare the importance of the various commandments and come to such conclusions. Rabin's assassination was also sanctioned by some according to Jewish law of "mosser". The Halakha was not updated much, certainly did not have a chance to evolve naturally under conditions of Jewish control over Gentiles. Since changes in it are extremely slow, it is best to override it, as was done in laws concerning financial issues, according to the ruling of "Dina d'malchuta dina", "the law of the land is valid." But I wonder how long it will take to also change the moral/ethical influence that goes with the outdated Halakha.
