.AS ANY PERSON that has actually feuded along with a neighbor knows, dumping rubbish over the hedge is a serious rise. Thus imagine South Korea's temper at the North, which has sent some 2,000 balloons, each lugging around 10kg of scree, all over the perimeter since May 28th. The best recent arrangement, numeration around 350, began getting there on June 24th. According to the South, the bags had paper, aged clothing as well as parasites that perhaps came from individual faeces. Why is North Korea sending its own rubbish south?
