In Israel, a disturbing new sign of radicalization:

A number of leading rabbis who signed on to a religious ruling to forbid renting homes to gentiles – a move particularly aimed against Arabs – defended their decision on Tuesday with the declaration that the land of Israel belongs to the Jews. Dozens of Israel's municipal chief rabbis signed on to the ruling, which comes just months after the chief rabbi of Safed initiated a call urging Jews to refrain from renting or selling apartments to non-Jews.

There is, mercifully, plenty of blowback from the Israeli left and center, including Netanyahu. But the logic of fundamentalism is as powerful within Judaism as it is within Christianity and Islam. And it's taking over in a way that makes politics and diplomacy impossible and religious war a theological necessity.
