North Korea’s underground nuclear tests have been condemned by world leaders, yet Associate Professor Tilman Ruff says the global community should not simply react by reprimanding the regime but ridding the world of nuclear weapons.
“There are around 25,000 nuclear weapons in the world and if less than half of one per cent of the world’s nuclear arsenal was targeted on cities it could result in a global climatic catastrophe that would imperil human civilisation,” he says.
