Thankfully they live within the nation of Israel so their rulers will provide some level of protection. Were they in the Palestinian territories they would come under the Moslem civil authorities as the poor Christians in Bethlehem have found to their sorrow.
Actually, the Israeli gov’t on many levels has been as clueless as any Western gov’t when it comes to recognizing the need to put the boot on this behavior. Christians in Jesus’s birthplace, not to mention other parts of Israel and “occupied palestine” are very often left to fend completely for themselves.
