.AS ANY INDIVIDUAL that has feuded with a neighbor recognizes, disposing rubbish over the hedge is a serious growth. Thus imagine South Korea's temper at the North, which has delivered some 2,000 balloons, each lugging around 10kg of detritus, all over the boundary since May 28th. The most current arrangement, numbering around 350, began getting there on June 24th. According to the South, the bags consisted of newspaper, outdated apparel and parasites that probably originated in individual faeces. Why is North Korea sending its rubbish south?
