Ibrahim el-Meneey, a powerful Bedouin tribal elder who lives a few miles from the Israeli border, said that arrangement would be ideal, as long as the military sticks to guarding the road. The tribes, which have stockpiled everything from small arms to antiaircraft missiles, are doing a fine job of dealing with violent human smugglers, drug runners and other miscreants who have taken advantage of the security vacuum over the past year, he said. “Here, it’s all tribes,” Meneey said, sitting on a moonlit sandy patch outside his house, which is close enough to Israel that cell phones roam onto the country’s mobile networks. “Security is very stable.”
