"Oxfam has just released a fresh appeal. It says the aid required is $260m short of its target.
But figures produced by the United Nations office for the co-ordination of humanitarian affairs show that $772m has already been pledged, the vast majority from the U.S., which has nearly trebled its aid to Ethiopia this year."
Ethiopia is a U.S. ally in the current geopolitical troubles in the Horn of Africa, which gives the U.S. multiple motives for trying to ensure that the current food situation in Ethiopia does not become a widespread famine of the kind that has afflicted the country more than once in the past. (Ideally, of course, humanitarian motives alone should be sufficient, but two motives are usually more effective than one.)
