.AS ANYBODY that has feuded with a neighbour understands, discarding rubbish over the hedge is actually a major escalation. Thus think of South Korea's temper at the North, which has actually delivered some 2,000 balloons, each carrying around 10kg of scree, across the boundary since May 28th. The most current bouquet, numbering around 350, began coming in on June 24th. Depending on to the South, the bags consisted of paper, old clothing and parasites that probably originated in individual faeces. Why is actually North Korea sending its own rubbish south?
