From the piece:
“She’s not a typical diplomat,” says Ed Luck, a former special adviser to the U.N. secretary-general. “She doesn’t suffer fools gladly, and I don’t see why she should.”
Luck said he had his doubts when Rice was named U.N. ambassador four years ago. He wondered whether her style would chafe, but he was pleasantly surprised and, at times, moved, particularly when Rice gave stirring remarks commemorating the Rwandan genocide and acknowledging that the United States did not do enough to stop the killing. “I don’t think I’ve ever seen quite such a personal and emotional account given by a diplomat at the U.N.,” Luck said.
