SANA'A, YEMEN ✦ The Yanks. We love 'em. We hate 'em. Indeed, Jean and I are still recovering from the news of the brutal slaying of threeU.S.aid workers, including a doctor friend, at Jibla missionary hospital. The killer, apparently an Islamic extremist, reportedly said he killed "to get closer to God." Right. And who better to kill than American Christians? It's killing two birds, innocent as they may be, with one stone. Indeed,U.S.foreign policy really has folks in a huff these days. In fact, many of us would bend over backward to disassociate ourselves from the Yanks. No?
