A small feel-good sliver in a feel-bad framework: Pihcintu, a sweet-voiced, multicultural chorus of refugee girls and women here in Portland, sang today at the U.N. to celebrate a new Global Compact on Refugees aimed at supporting the largely poor countries that host the world's 25-million-plus refugees. The compact, which will help the U.N give food, shelter and succor like that once accorded Pihcintu members, was approved by all but two countries; the U.S. was one.
